After some reading and thinking, I came to a very similar conclusion. There are tons of parameter which will influence the mesurement.
I am planning to use four or five moisture probes distributed at various places in my garden for irrigation automatisation. I guess my lawn will not suffer if I start watering at a reading of 41 % instead of 44 % ;-)
During the upcoming winter months there is enough time to gather empirical data about the behaviour of my probes.
Anyway, it's a fun project ...

Hello,
I am relatively new to MySensors and now trying to get my first sensor up. My serial gateway runs on an Arduino Uno, which is connected to a Raspbery Pi 2. So far, so good.
I am now trying to prototype a temperature/humidity sensor with a DYPTH01.
I get a bunch of debug output from the gateway and from the sensor (also on a Uno) , with quite a few of "fail", so I guess that something is wrong. Now I am trying to find out what is wrong ...K
I have searched quite a bit, but I was not successful to find any documention on how to interpret the debug output. May I ask a kind soul to please point me to a description ? Or have I really browse through the source code of MySensors ?
Any help is highly welcome. Thanks a bunch in advance.
Cheers,
Josh

OK, after some fiddling I was able to exchange mysensors V2.0 with V1.5.4 and to compile mfalkvidd's sketch. I will adapt it now to my hardware (removing references to LED etc) and give it a twirl. Please be patient, since I need to run it at least a coupl eof days to see if there is a difference in power consumption.
Very interesting stuff :-)

Thank you very much for your reply. I know that part of the documentation quite well, since I have written a serial gateway emulator to send sensor data, which is collected locally on the Raspberry Pi to the controller (Domoticz). My question relates to the other stuff, which looks like 0-0-255-255 pt=7 c=3 etc. My guess is that this is the debug information, whereas the other stuff (0;0;3;9; as an example) is the serial gateway protocol. I would like to know the meaning of the debug messages, because I think these may be useful to help me in debugging my code.

Thanks a lot again
Josh
