messages from sensor doesn't seem to appear on gateway, st=ok [solved]
-
Hi,
I'm trying to put very basic config together for the first time and it seem that I'm missing something very obvious here.
I have made a serial GW connected to RPi2 running OpenHAB 1.7.0 on top of Ubuntu server and sensor node with 3 sensors attached: DHT temperature and humidity, BMP180 pressure and simple soil moisture. Both Adruinos are Pro Mini. I have downloaded 1.4.1 MySensors library, I use Arduino IDE 1.6.4 on OS X.
I have put together sensor node sketch from library examples. After some tinkering it seem to me that I've got communication flowing, but messages seem empty! I've looked at it for a while, tried to google it but with no result so far.
Please help me with advice! I will read detailed API and protocol descriptions meanwhile :)
Here is sensor node sketch:
