BTW - I called Ambient today and they suggested a hard reset performed by 
holding the up arrow for 30-seconds.  For the moment, it is reporting again.

[weewx-user] Re: 'rainBatteryStatus' on TFA Opus

[Luc Heijst]

Sorry, I forgot, the signals of the wind and rain sensors are received by the 
outside temp/hygro sensor.
The outside temp/hygro sensor send these signals together with its own values 
to the console.
The wind and rain sensors have a reach of 50 meters (maximum) and the 
temp/hygro sensor 100 meters.
So dashes for the rain value might be a combination of lower voltages on the 
rain sensor and/or lower voltages on the temp/hygro sensor.
Other factors are distance between the sensors and plants and trees which 
influence the communication.

[weewx-user] Re: 'rainBatteryStatus' on TFA Opus

[Luc Heijst]

When your rain data show dashes on the console you probably won't have 
communication between the rain sensor and the console. 
This could be caused by batteries with lower voltage. The voltage might be high 
enough to not trigger yet the low-battery warning.
You might try to change the location of the rain sensor or console to get a 
better radio reception.

Re: [weewx-user] Save reports to a temporary file system

I just rebuilt my pi3 with a WDLabs piDrive ... 256gb of disk goodness ...

Yes it boots off the SD Card but it only reads the SD for boot as its

[weewx-user] Oregon Scientific WMR300 issues reading outside temperature and humidity into weewx

[Markus Benedikt Biewer]

Hi there weewx users!

With great help with the WMR300 driver through this supportive user group 
here, I run weewx since beginning of March 2018 on a ubuntu 16.04 on a 
raspberry alike hardware. After a couple of weeks (only) the outside 
temperature and humidity are not correctly shown anymore.

It started with a few intermittent dropouts during the day and became worse 
and worse and now almost no outside temp and humidity are shown anymore.

The LCD of the weather station shows the data without any problems.

This is my servers address:
http://woustviller.com/weather/

I have also configured wunderground and their website shows the same 
problem, check it out:

https://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=IWOUSTVI3

I really would appreciate any help what the problem could be. I am not 
veery experienced in Linux but I have a ssh access to my server and I am 
happy to post any information here that might help to locate the problem.

Cheers,
Markus

[weewx-user] WS2080 not talking USB

[Paul Grunwald]

I have a 4 year old WS2080 that I have been using with Weewx.  The USB 
seems to have died.  I have reset the console a couple of time pulling the 
battery.  I have reinstalled Weewx (Debian 9) and I can "sometimes" read 
the config, and I removed a powered hub and connected the console directly 
to the server.  

Questions:

What else can I check?
Any easy fix?
Recommendations for a new unit?

AFAIK, I will have to change path //home/weewx/ to //etc/weewx/ and 
use /systemctl restart weewx/ for restart Weewx.

Something else?

[weewx-user] Re: weewix on PI3 FAIL!

[Andrew Milner]

1.  it helps to tell us exactly what commands you have given, and with what 
responses
2.  you will find that you will need to have knowledge of basic unix 
commands
3.  make sure you have read the comments in the wiki regarding raspberry 
pi, weewx and weather stations
4.  get weewx running with the simulator before attempting to work with 
your weather station
5.  small steps are much more productive than giant leaps into the unknown!!

weewx outputs quite a lot of useful information when it is started - so 
finding the log has to be your first issue!!

it is  much easier if you have weewx logging to its own logfile (weewx.log) 
- again see the wiki

the wiki and the documentation are your main sources of information

as I said - get weewx working with the simulator first of all

when you post to the forum do try and follow the guidelines - how you 
installed, what commands you have given, what is the result

I'm sure you will succeed and be over the moon with weewx very quickly - 
but there IS a learning curve, and some basic Linux knowledge is 
exceedingly beneficial.

PS  there will be nothing created, no data in www folder until the end of 
the first archive period - the length of which depends on your weewx.conf 
settings and/or your hardware.

[weewx-user] weewix on PI3 FAIL!

['Stuart Smith' via weewx-user]

Hello all and thanks in advance for any help.

Newbie to Linux so hoping you'll be kind ;-)

Have just purchased a Raspberry Pi3 and am wanting to use it with my Fine 
Offset weather station running weeWX.

I have installed the software but when i use the code to check the logs i 
see no reporting that i recognise from weewx.

There is also no www folder in the var folder on the Pi.

Thanks again, tried searching for help before posting.

Re: [weewx-user] Re: Looking for help with Oregon Scientific WMR 89

[dani . macias . perea]

Hello again,

I have been experimenting with François drivers since last Wednesday and I 
have found a couple of problems:

   - In the driver, the rain packet does not contain the attribute *rain*. 
   I have used the version from WMR100 driver and I think it is working 
   correctly now: _record['rain'] = weewx.wxformulas.calculate_rain( 
   _record['rain_total'], self.last_rain_total) self.last_rain_total = 
   _record['rain_total'].
   - I get some estrange values in the outHumidity sensor: "LOOP value 
   'outHumidity' 252.0 outside limits (0.0, 100.0)". I am not sure if the 
   problem is in my station (I was not able to see the humidity value in the 
   console) or in the driver. Will try to have a closer look in the next days.

Regards,

Daniel

Re: [weewx-user] Re: weewx crashes with error: unpack requires a string of len 104

[Graham]

Using the revised hp1000 driver with delay of 30 and starting weewx manually I 
can see all the records coming through on the terminal. I can see the process 
stopping as the records just stop coming through and the cmd line returns. 
Additionally no further reports are generated. I haven’t tried ps on this 
version of the driver but returning to the cmd line would seem to indicate that 
the process has stopped.

Using the original driver with delay of 30 produced the error after random 
times (ie there was no consistency as to how long the process would run for) 
that started this thread off. Ps did not show any running process for weewx 
following this.

The delay of 15 seems to have resolved the issue from my perspective as it has 
run continuously for 3 days but I must admit I’m puzzled by the  error

 Hi Susan
 
 Regret to say that weewx stopped running again without writing anything to 
 syslog, messages or user.log. Syslog shows that when weewx starts it is 
 using the correct version of the driver, so I’m puzzled as to what is 
 going on. Would you like a copy of the syslog file in it’s entirety to see 
 if that throws up any clues?
 
  
 
 I’m going to run weewx again but with your original driver to see what 
 happens this time. Incidentally if I set the loop-delay to 60 secs the 
 program doesn’t run at all – currently set at 30secs.
 
  
 
 Sorry to be a nuisance!

 G - too long since I wrote the code and I made a stupid mistake. The 
 two 'loginf' lines should read
 
  
 
 loginf('Bad data: length = {0}'.format(len(rxData)))
 
 loginf('Bad data: "{0}"'.format(rxData))
 
  
 
 I've attached your file with the correction in it.
 
  
 
 Sorry about that.

With a RaspberryPi 3 you can boot directly to a usb device cutting out the SD 
card completly. The Raspberry Pi Foundation has a tutorial on how to do this.
