Interesting idea. I've been tempted to build a special owserver that has
plug-in sensor code -- owexternal.
The plug-in would get a separate mane space (perhaps
/external/sensor43/humidity) and have to report a few properties like
length, type, read/write and volatility.
Plugins could be written
It is the voltage regulator heating up the board, it usually stays at a
consistent amount so you can
subtract the "offset" and get the correct temperature. Also the DS2438 has self
heating issues so I
would not use the temperature from the DS2438. We offer the combined board but
we recommend u
Yes good points, desk lamp is not an issue but I guess it could be a
voltage reg issue. I have also just discovered that my wiring does not
supply +5 to the sensors, which I thought it did. Need to review that
and test again, but that's a job for tomorrow, it's getting late now!

I was wondering if this error is persistent? If I put all my sensors in one

I have a test setup with 4 DS18S20 temperature sensors and a Hobby
Boards Humidity sensor with built in temperature sensor. They are all
currently on the desk within a couple of inches of one another so should
all read the same temperature.
Two questions

It surely is, my last summary posted here:
http://article.gmane.org/gmane.comp.file-systems.owfs.devel/9120
2.8p2 seems much more stable as the reset_error
Just noticed one thing in 2.8p14 (also 2.8p8):
DS2413 used as input, sensed.BYTE is fine but
sensed.ALL & .A/.B shows always 0
This used to work fine back with 2.8p2

Hi Michael,
maybe what you experienced is the same what I already described in another
tread.
- Is only one DS9490 got lost and the others still continue working?
- Maybe this one have a high capacity between data-wire and ground
(due to a wrong placed Capacity or very long cable)
- Did you tri
Hi all,
beside using 1-Wire devices I would like to use other sensors as well.
Currently I play with an temp-sensor getting data very simple by a serial
port.
So writing all this polling, retry, alias, fuse (and a lot of other
functionality) again is a lot of effort - so maybe there is a way to e
