[Owfs-developers] Simple program switching a DS2405??!
-- weitergeleitete email --- von:: cettl an:: owfs-developers@lists.sourceforge.net betreff:: Simple program switching a DS2405??! datum:: 19.01.08 23:49 Hello sourceforge community! This is my first mail directly to you, and I hope, someone here can help me (Please)!! I?m a newbie in all this 1-wire things and Unix. I have a DS2405 which I want to control with the help of the NSLU2 from a web browser. With hardware, I have no problem (since I?m an analog designer), but with software, hehe! Here is my status, what is working and what not: What?s already functioning now, are the commands: owwrite 05.24302C00/PIO 1 owwrite 05.24302C00/PIO 0 I can see this DS2405 also in the web browser of the owfs written by Paul Alfille (http://192.168.1.77:3001/Serial_Number_of_device). Unfortunately, the PIO changes only from ?off? to ?on?. I also tried the perl temperature reading program by Paul Alfille. Over the web browser, I can see the temperature, but the program running on the NSLU2 gives back an error message. However, I have absolutely no idea about is how I do this web browser connection by MYSELF. Yes, in principle, this web browser from Paul does exactly the same thing I want, but with the difference that all this is somewhere written and distributed in the 10 files of this owfs. So what I badly would need is a VERY SIMPLE program which does change the output of the DS2405 when clicking with the mouse. But now, everything is integrated somehow (and I cannot follow how) in this large owfs. I have to start with a very simple program and then, it should be no problem for me to add some code to make more functions I want. What I want at the end is making a water plant system: The NSLU over the 1-wire measures the water level on a plant and controls a DS2405 which controls a valve to water it. This system should run on itself and for maintanance or for adding a plant I want to connect the computer and see on the web browser which plant got how much water and so on. And now I beg if anyone could be so nice and write me this very little program which does the following: When I click with the mouse on the button ?ON?, this DS2405 should switch on, when I click on the button ?OFF?. For me, it is important that it is a very simple program, consisting only of some lines (I heard, perl would be good). As I said, it?s no problem for me to continue by myself and enlarge this little program with more functions etc., but now, I have absolutely no idea how to start. I tried already some perl programs (e.g. reading the temperature from a DS THANK YOU in advance for your willingness to help me!!

Re: [Owfs-developers] DS1821 Thermostat support and reset circuit
Your choice. Either send the code and the schematic/instructions to me, or get added as a developer and add it yourself. And thank you. Paul Alfille On Jan 20, 2008 9:44 PM, Doug Collinge [EMAIL PROTECTED] wrote: I have just completed support for the DS1821 thermostat chip, implementing all the features in the datasheet. It is tested and ready to commit as far as I can tell. What should I do with it? One of the little issues with the DS1821 is that, once you program it to be a thermostat it stops listening to the 1-wire bus so you can't unprogram it anymore. That is, unless you generate a magic reset sequence, which you can't generate on the 1-wire bus. Not to worry... I designed a little two-chip circuit that generates the necessary sequence that you could whip up in 20 minutes on a protoboard. You might even have all the parts on hand... It's all documented and ready to upload if you think anyone else might find it useful. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Owfs-developers] DS1821 Thermostat support and reset circuit
Very nicely done, Doug. Code, man page, circuit schematic with explanation, timing diagrams and photographs. Just to remind everyone, the DS1821 is a pseudo-1wire chip. It has no unique address. It can be taken out of 1-wire mode by software, which then makes it unreachable. We get around the no-address problem by blindly sending commands to and reading from device thermostat. Any DS1821 in 1-wire mode will respond appropriately. Doug's circuit gets around the second problem -- switching the DS1821 back into 1-wire mode.

Re: [Owfs-developers] OW.pm (Problems with AAG TAI8558/DS2408 and DS9097U)
Should be fairly simple (but I'll test to make sure it still works). The source code is generated by SWIG under modules/swig/ow.i (C-code). There is a man page, and a POD page, and documentation on the Web site. And example code. In general: use OW ; OW::init(-u) ; print OW::get(/) ; OW::finish() ; Paul Alfille Another option is to use OWNet.pm -- it connects to owserver and is fully object-compatible.

To be fair, I haven't looked at the POD page yet, so perhaps there is more. I did run the example, but it gave me a blob of info rather than more digestible chunks. That's alright, but I'm unclear what the OWserver gets me beyond OW.pm (or even what OW.pm gets me beyond what OWFS has) if I'm using everything on localhost POD and man are the same, I think. One think I am trying to get (either directly or indirectly) is signals/callbacks/alerts when new devices are added. It seems I can either poll the interface or watch the file systems (which is effectively the same thing, AFAIK). Watching the file system seems like a pretty easy, standard way to do this, although I wish there was some way to set refresh rate lower than 1 second. Slower or faster? 1-wire isn't all that fast in the first place, you know. I think the SELECT function is used for shorter delays. Which leads to a question. Does the owserver 'push' new data to clients, or does it expect clients to poll? It seems like it expects clients to poll. Pull model. (Like a filesystem). Note that 1-wire itself doesn't reliably notify of updates. (A least not in multiuser environment when other data transfer can mask a presence pulse.) Some of the 1-wire low-level communication has direct polling (keeps sending 0's until the measurement is complete). We don't use that since it stalls the bus and prevents all other communication. It's a design choice. Paul Alfille - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Owfs-developers] New release: 2.7p4
I'm releasing a new OWFS version: 2.7p4 The major change is better configuration file format. The man page is at http://owfs.org/index.php?page=configuration-file But the new feature is program-specific lines. An example: owfs.conf -- # set up owserver's port server: p=4304 # only owserver sees this line !server: s=4304 # all programs BUT owserver see this line server: u # only owserver connects to the USB device F # All programs use Farenheit http: p=3001 # owhttpd is on port 3001 ftp: p=2121 # and owftpd is here fs: m=~/1wire # owfs sees this mountpoint Then all programs can use the same configuration file. Prior to this, general configuration options could be shared, but port addresses would conflict. owserver -c owfs.conf owhttpd -c owfs.conf owfs -c owfs.conf owftpd -c owfs.conf The point of this is to ease configuration of embedded platforms.

O.k.Then, I entered the following URL in my web browser http://192.168.1.77/var/hello_world.pl;, but of course it did not work.

[Owfs-developers] Fwd: Simple perl program
-- Forwarded message -- From: [EMAIL PROTECTED] Date: Wed, Mar 12, 2008 at 5:50 PM Subject: Simple perl program To: [EMAIL PROTECTED] Dear Paul, dear Jan! Thanks for your answers! Paul, I followed your steps and the program is working. I could switch on and off the DS2405. However, I think it was a misunderstanding. This program is executed on my real computer just linking to another URL which controls the owfs running on the NSLU. What I need is a simple perl program executed on the NSLU but being controlled from the real PC only. Since my watering plant system should run stand alone on the NSLU and for changing some parameters I connect my computer to it. This means, I would need a e.g a simple program (maybe describe it in a better, different way:) running on the NSLU which, e.g. every second toggles the DS2405 and by connecting the PC with Firefox, I change this time to every 2 seconds. This interface is the thing which is absoultely not clear to me. What must run on the NSLU and how do I access it from a web browser. E.g. I wrote some code for the ATMEL ATMEGA. Here, it's clear: The program is executed there and from time to time, I connect the PC and over the RS232 I change some parameters. But with this OWFS I don't understand anything how it's working. For instance, if I connect a new device, it's perfectly recognized by this OWFS and displayed in my web browser. My main question is, how can I MAKE USE of this nice system? And here are only you who can explain me in this case. E.g. if, for instance, I have to learn better a programming language, I just buy a book and start to study it, it's easy. But here, how the executed program on the NSLU is working together with the firefox I have no idea. Therefore I need such a simple program, to start to understand the connection. Jan, sorry, I didn't understand anything you tried to explain to me. 1. What's a Content-Type:... header and what does mean CHECK. 2. What is wwwrun, a certain file in a certain folder and if so, where it is placed in the NSLU or on my PC? 3. As far as I know, I have no web SERVER, do I? I have only a web BROWSER named Firefox. By the way, I don't know what Apache is. 4. What do you mean by enable an extension? I'm used to files which HAVE a certain extension, the thing after the full stop, e.g. .mp3 or .jpg. Did you mean I should create an extension, that the file gets the name test.cgi for instance? So, after all, do you have a more concrete example for me? As I said, I have this Unslung 6.8 running on my NSLU2 with also a running OWFS 2.7 on it. It's IP address is 192.168.1.77. Over Ethernet I'm connected to a PC with Windows XP and Firefox. Does this help you? Paul, by the way, how can I directly post to the mail listing. For sure it's not convenient for you to put my mails there every time. I registered on sourceforge but I still cannot post. I always get the error message: You are not allowed to post to this mailing list, and your message has been automatically rejected. If you think that your messages are being rejected in error, contact the mailing list owner at [EMAIL PROTECTED]. Thanks again a lot for your answers nice greetings, Bernd --- Ok, you certainly weren't clear in your requirements. To run a U2 is easy. You wouldn't run it in a web server or browser, but rather stand-alone. Something like: #!/bin/sh while : do owwrite /tmp/1wire/05.2342342343/PIO 1 sleep 1 owwrite /tmp/1wire/05.2342342343/PIO 0 sleep 1 done Now to make changes from your host, there are several ways. Since the NSLU2 is a file server, just have the configuration file be writeable from your XP host. Or ssh. Or set a web interface (but it certainly is harder to do). As for the mailing list.

Re: [Owfs-developers] Simple perl program
I just noticed I screwed up the syntax for owwrite. owwrite writes to the owserver and uses the pure path for the 1-wire device: e.g. owwrite 05.2342342343/PIO 1 or more formally: owwrite -s localhost:4304 05.2342342343/PIO 1 If using the FUSE filesystem, then your need a valid filesystem path. e.g. echo 1 /tmp/1wire/05.2342342343/PIO (If owfs is mounted at /tmp/1wire) Sorry for any confusion.

Re: [Owfs-developers] My OWFS driven website update (Aquarium)
As answered in another thread, FUSE is only needed for owfs (the virtual filesystem). It's a little confusing since the whole package is called owfs (for historical reasons). owhttpd, owserver, and all the others don't use FUSE. I'll take Robert Conway's word that he finds owserver/owshell more robust than owfs. The first uses the owserver protocol (tcp/ip messages) to answer 1-wire queries, the later uses FUSE and filesystem callbacks. YMMV on this, I've had a owfs/FUSE data collection system running for literally years. FUSE is more finicky about kernel versions, user permissions and startup sequence. On the other hand, every single program in the world knows how to read a file, and owfs/FUSE looks just like a regular file. Paul Alfille As far as the architecture goes, almost all the code is shared between the programs, in libow. owfs, owhttpd and owserver are only thin layers with the unique features, linking in libow with all the 1-wire knowledge, networking, caching, address parsing, argument processing, etc. That's why using owserver and calling owread 10.012345667/temperature or using owfs and reading file 1wire/10.012345667/temperature give the same result.

Re: [Owfs-developers] NSLU2: owhttpd Webserver not reachable with browser
That's right. The multiple listing is not a bug. Multithreaded programs are listed for each thread. I notice that you are running oww and owfs. They will probably compete for the actual 1-wire adapter. oww is particular will poll the 1-wire bus periodically. At some point a shim oww to access the 1-wire bus via owfs is planned, but it's a slow process. I'm not sure why you can see the 1-wire bus with owfs but not owhttpd. One problem might be that owhttpd isn't on port 3001. I can't tell which port from the command lines shown. If no owhttpd port is specified, an ephemeral port is assigned by the OS, usually relatively random and hard to locate. Can you show the startup script or configuration file?

I would like a mean to debug out this situation where: - I can use the system with a USB to serial adapter and a MAX233- this means the circuit on the 1W side is ok - I cannot connect the 1W through the internal serial port, but I can use that serial port to communicate (through the same MAX233) The key here seems the MAX233, without it I cannot communicate. The question is, without using the OWFS tools, how can I ping or see if the DS2480B is 'alive'? Can I send a character on the serial port and expect an answer?

Re: [Owfs-developers] owcapi: return-value of OW_init?
Yes. There is no hello sequence with owserver. Your program will wait
until owserver is available. Clearly waiting for data from owserver will
time out. Think of init more like starting a web browser.
This way, you can start owcapi with series of adapters listed (serial, usb,
owserver) and the valid ones will be used.

Hello,
OW_init does not seem to return a non-zero value if no owserser is
running on a given port! Is this the intended behaviour?
Try this:
#include stdio.h
#include owcapi.h
int main() {
int ret;
ret=OW_init(localhost:12345);
printf(ret: %d\n,ret);
}
I would expect to get a non-zero return value, if no owserver ist
running on port 12345 in this case?

As far a I can tell, Maxim doesn't make a product with RJ45. All their kits are RJ11.

Usually when conducting, the sensed voltage will be ground, since it's essentially grounded. The names are from the data sheet, latch is the conducting state (what you SET) and PIO the sensed state (when read).

For a couple of sensors, you may as well just monitor directly. You can do more sophisticated temperature control that way as well (rate of change, etc) You will have to do temperature measurements in any case. The alarms only make sense if you have many non-parasitic sensors and do a simultaneous conversion and then use alarm to find the sensors out of range.

Re: [Owfs-developers] DS2450 and voltages
It's certainly possible to give the raw byte sequence. There is a slight wrinkle that the DS2450 does A/D conversion either 0-2.5V or 0-5V and we use the requested property to transparently set the correct resolution. From modules/owlib/src/c/ow_2450.c: // data conversions f[0] = (resolution ? 7.8126192E-5 : 3.90630961E-5) * UINT) data[1]) 8) | data[0]); f[1] = (resolution ? 7.8126192E-5 : 3.90630961E-5) * UINT) data[3]) 8) | data[2]); f[2] = (resolution ? 7.8126192E-5 : 3.90630961E-5) * UINT) data[5]) 8) | data[4]); f[3] = (resolution ? 7.8126192E-5 : 3.90630961E-5) * UINT) data[7]) 8) | data[6]); Are you using a platform where floating point arithmetic is inconvenient? I'm told the true resolution is only 8 bit even though 16bit is set, so rounding errors are probably irrelevant. If you want the raw reading, can you suggest a good name? A2D ? raw_read?

Re: [Owfs-developers] DS2450 and voltages
Allesio After a conversion (measurement) is done, the raw data can be read from memory (page 0). This is a little less efficient since the memory page is read twice, once for the voltage and once for the page. Still, data A/D is probably the slowest part of the sequence. The data sheet calls these the conversion readout or conversion registers. Not the best name for a property.

Well I do not have an FPU, but floating point is possible anyway, and this application will just do a FP multiplication every now and so, it should not be a problem. From the DS2450 datasheet, page 22: In the shaded areas [8 bit resolution] the accuracy is less than the resolution. The conversion results may include random noise.

Re: [Owfs-developers] OWFS and WRT54GL
I can't answer about assembled WRT54GL, but there are a number of devices with functioning USB ports: WRT54G(S), ASUS-WL500gd, ASUS-WL500W for wireless routers NSLU2 for USB and wired device. Paul Alfille I've sent your query to the developer's list for other input. On Thu, May 8, 2008 at 7:29 PM, Quark IT - Hilton Travis [EMAIL PROTECTED] wrote: Hi Paul, I've been running WRT54GL (and some earlier G and GS) units at client sites for some time now with various OSes installed (default, OpenWRT, DD-WRT) and have been pretty impressed with the longevity of these units and the variety of software and hardware mods that have been cooked up for them. It just goes to show what a good dev platform can be used for when the community gets behind it! J Anyway, I'm about to purchase some pythons from a mate and due to the amount of electronic gear at my place, am a little concerned that if I'm not here and the temps get a little carried away, that maybe this will stress the snakes and cause issues I'd rather not cause them. Out of interest, I've just bought 2 * Jungle Python yearlings (about 2 feet long) (general images at http://www.southernxreptiles.com/JUNGLEGALLERY.htm) and a 3' Bredli (general images at http://en.wikipedia.org/wiki/Morelia_bredli) from him. What I'm looking at is using a WRT54GL with a serial port hack and OWFS to monitor some TAI8540D units (http://www.aagelectronica.com/aag/index.html) so I can measure both temp and relative humidity. If possible with OWFS, I'd also like to be able to use the TAI8555 1-Wire Switch module to control a relay to a fan, light source, heat source, cooling source or something else. An alternate device to a hacked WRT54GL would be the Asus WL-500G Premium (WL-500GPV2) that has an inbuilt USB port and using a USB 1-Wire adapter instead of a serial one. So, what I'm basically asking is if you still have any assembled modules available or if you know of anyone who has assembled modules available for the WRT54GL. I don't mind drilling a few holes in the case and plugging a connector into the onboard header, but I don't really have the gear for soldering together components or making a circuit board. Or do you know if the DS9490R USB Adapters work with OWFS and a USB-equipped WRT54-like device? The really good thing about this as a solution is the ability, I'm thinking, to be able to record this data for quite a while on the device itself, or better still, to be able to send the results via syslog (or other method) to another box via Wi-Fi, meaning that these units could be scattered wherever needed and not need Ethernet cabling to hook them all into the network! Would be really nice if your snakes, fish, birds or whatever are not near your computers yet you'd like to monitor them. Any and all information will be much appreciated.

Re: [Owfs-developers] PL2303 DS9097U Don't commuicate
In general, the USB/serial conversion should work transparently. Obviously your would specify -d /dev/ttyUSB0 on the command line -- assuming that is the assignment linux is making (dmesg should confirm this). I suppose some USB/serial adapters might not be as faithful. The DS9097U does need to steal power from the line. I notice that one device is seen, a DS2502. Is this correct?

Re: [Owfs-developers] PL2303 DS9097U Don't commuicate
Let's try some simple steps. If you disconnect all the devices, does the base DS9097U seems to work? Can you run the device with --foreground --error_level=9 and post the results?

Re: [Owfs-developers] DS1923
Support for the 1921's, 1922's and 1923's has been a stalled for while. Part of the problem was coming up wth a coherent filesystem for a very complex device. The other problem was aliases -- changing one property (starting a mission) changes the state of items like running, etc. Recently the alias problem has been fixed with. the sibling functions which have first been applied to switches (PIO an sensed for example). I have 1921,2,3 to test with. And clearly there is interest in the devices. The only outstanding architecture issue is handling passwords for the 1922 and 1923.

Converting to C++ wouldn't be impossible, just quite a chore. More to the point, problems in OWF have been with hardware -- network and serial/USB handling and 1-wire device protocols. In general, the mutex issues have been with subtle incompatibilities between glibc and uclibc. That said, it is hard to argue against program correctness. Perhaps a special testing option that adds a check to every mutex operation and abort if there is an error? I suspect you are more likely to deadlock than see an error.

Re: [Owfs-developers] How to Use Simultaneous
Your second use i the correct one. Write 1 to simultaneous to trigger a conversion. That also clears the cache.

I have multiple DS1820 devices on a bus. They are all powered devices. I want to simultaneously convert them all, wait, then read them all. I'm expecting that when I go to read them, since I have signalled a simultaneous conversion, that they will all be already converted and ready to send their data, .except perhaps the first one if I haven't waited long enough for the conversion. I'm writing a 1 to '/simultaneous', processing some other stuff, then reading them all. If I read from '/uncached/temperature' it takes 600-some-odd milliseconds to read each one, which sounds like they are all doing a fresh conversion. If I read from '/temperature' then I get them read in much faster but I don't get a fresh conversion each time. What I want is for writing to '/simultaneous' to always kick off a fresh conversion of all the devices so that I always get a new sample when I read them, and never take data out of the cache.

Re: [Owfs-developers] need help in sharing owfs 1wire data between multiple BASH scripts
Hi Rob, Interesting questions. 1. Each of the owshell programs (owread, owwrite, ...) are small utilities. They do require a process creation and a tcp connection setup (no persistent connections), but that may be quite acceptable on a modern server -- the 1-wire bus tends to be the limiting step. 2. owserver handles the multiple requests (I assume from different looping scripts so concurrent) fairly efficiently. The whole bus is locked when required, and individual devices are locked if a longer transaction is needed. Still, there is no prioritization on lock or device access. It wouldn't be hard to do, but we should establish a need before adding more complexity. 3. Sharing data between processing is easiest with a database, Probably ram-based. An alternative would be using perl with OWNET.pm where a complex loop would be easy with shared data 4. Looking at the perl threading model, http://migo.sixbit.org/papers/Perl_Threads/ it appears that sharing data between threads is possible http://search.cpan.org/~jdhedden/threads-shared-1.24/shared.pm but I'd have to investigate further whether the module is reaqlly thread-safe (there is a small amount of state data on the network connection and persistence that might not like being shared, though each thread could set up it's own connection to owserver).

A couple of questions:
1. This doesn't seem unique to the LINK. Should it be used for all serial

2. Why would the write block?
About the specific code:
Is there a guaranteed exit to the loop?
Also do we need the pause for non EWOULDBLOCK errors?

Polling e.g. a motion sensor or a door contact a couple of times per second doesn't work when there's e.g. a temperature sensor on the same bus, as reading that thing takes 1 second. Good point. Some suggestions: 1. The DS2482-800 lines have some cross-contention (only one can be read at a time), but the 1 second conversion delay with the bus powered high should be ok. 2. OWFS spawns a separate thread for each request, so queries on different busses should be fine. The only time a request ties up all the busses is when OWFS is finding the location of a device, and when simultaneous conversion is requested. a. You can specify the exact location of a device by /bus.1/10.1231231231 although it's a little fragile. b. The locations are cached. If the design is fairly static, increasing that timeout would be more efficient.

The reason for the quantity of 5 DS2482-800 is, that we need to know where a Dallas ID is connected to (The sensor connector in our case), so we need dedicated one-wire lines. All of our I2C devices run on different I2C addresses, so there is no address conflict on the one and only I2C bus I have. Now I tried to find a convenient way to talk to my DS2482-800.

Re: [Owfs-developers] Single i2c bus, but multiple DS2482-800, again
Ok, I looked through the documentation. You have multiple I2C slaves on a single bus. We currently cycle through the available addresses and take the first responding one, ignoring the rest. It looks quite doable to add support for more i2c adapters, but there are some architectural issues. 1. OWFS design, accessing the separate slaves. a. does the slave address need to be set before every access. b. do I need to share the same file-descriptor for the different slaves. 2. Command line interface a. automatic detection b. specifying a specific address c. more than one instance of OWFS assigned to different i2c slaves. Basically a balance between convenience and precision. One thought is to use the same strategy as the USB, --usb=1 --usb=all, ... = --i2c=all (although this could be the default, except it would be different from usb) Unlike USB, however, the i2c slaves can be distinguished by their address. I need input on the best design. Paul On Tue, Aug 12, 2008 at 5:20 AM, Hans Detter [EMAIL PROTECTED] wrote: thanks for your reply.

I'm not sure if scanning all the i2c busses is safe. There seems to be a list of available i2c adapters in /sys/class/i2c-adapter/ and the names can be shown by: cat /sys/class/i2c-adapter/*/device/name I'm not sure if a non-root user can see or access all this. The potential addresses for the DS2482-800 are 0x18 through 0x1F. Although it's not hard to specify, I'd like that to be the non-default.

Re: [Owfs-developers] newbie help
Hi Calvin, 1. The 1-wire bus certainly is hot-plugable. In fact whole industries are made using intermittent contact of ibuttons for security locks, watchman rounds, etc. There is a delay in registering the new device under OWFS unless you look at the uncached directory (just for performance, so the bus need not be completely scanned for before every access). 2. The directory being hosed: This is a fuse issue, I've found that umount /tmp/1-wire resets things. 3. owhttpd is actually easy to use. In your case: after booting, do: /opt/owfs/bin/owserver -u -p 4304 mkdir /tmp/1-wire /opt/owfs/bin/owfs -s 4304 -F -m /tmp/1-wire --allow_other /opt/owfs/bin/owhttpd -s 4304 -F -p 3000 Note the differences: 1. owserver now controls the USB port, and owfs talks to it. 2. owhttpd also talks to owserver (that's why we started owserver). 3. the web access is localhost:3000 on that machine, and ipaddress:3000 elsewhere. Please report your success or problems.

Re: [Owfs-developers] OWFS on Ubuntu 8.04
I'm confused. This patch seems to have been implemented back in June. I
guess the problem is that there aren't any new releases. I'll release one
today.
In fact, browsing the code in Sourceforge:
http://owfs.cvs.sourceforge.net/owfs/owfs/module/owlib/src/c/ow_com.c?view=markupshows
your code.
How were you getting your version?

Hello,
I'm using several DS18B20 in powered mode connected to a DS9490R USB
adapter. OWFS version is 2.7p4 (I have tried today's CVS version, too).
The temperature is always showing 85C, which seems to be some kind of
error code. But reading the sensors with digitemp works.
I saw some older post regarding this topic, but I couldn't find a
general solution.
Is there a patch available? Any hints?

Can you run with full logging (error_level=9) and see if it takes 2 or 3 attempts every time? I wonder if it's the attempts, or the code for powered reads that is the problem.
