I've been using 'Heatermeter' for years, it's awesome!

If you only comment out the line with "sendCommand()" how often does is the rule triggered? My guess: only once. You need to distinguish if you're getting a request from the node or sending an answer.

@hek Thanks for the comments. Sounds good. I'll report back when I have some progress.

@moskovskiy82 You will find the discussion in the threads if searching. The current v1.5 gateway is a (rough) broker with some problems (even though mine has run well for a long time). The next one is a MQTT client and is based on ESP8266 and is available from the development branch at GitHub. Using this you also need a broker, for example Mosquitto, somewhere in the network. I have just installed Mosquitto at my Openhab RPi gateway and will start testing the WSP8266 MQTT gateway client one of these days. I have already run it for a few minutes and it worked so far.

@5546dug That's an interesting build. I've come across several using a PID controller similar to that, however they have mostly been on electric smokers. My original intent was to do a PWM fan that could be speed controlled, but it was very hard (impossible) for me to find a blower type fan that was PWM-capable. My very initial testing showed that an on/off model would work as well but I haven't tried this on the Big Green Egg yet. My main concern is being able to feed a temp from my phone back to the arduino controlling this, and being reliable if for some reason wireless connectivity was lost from the arduino. I don't think this should be too hard, but will probably take some trial and error on my part.

@Chester good point, but I was restarting the arduino and still couldn't get this to work correctly. Also, the missing "end" was just missed out of the paste here, it was in my code.

So I still haven't quite figured this out. There doesn't seem to be any information out there on this feature, at least not that I can find. I believe I've successfully transmitted "101;255;3;0;6;I\n" from my gateway, which from what I understand should set the sensor node to Imperial units. While watching the serial monitor on the sensor node, I did not see anything received and the units did not change. There is a possibility that my code did not transmit that code successfully, however the rule associated with the command was triggered successfully and I'm not sure of any way to verify. I know what I could easily modify the code on the sensor node to change the units, however I like the idea of being able to control multiple sensor nodes centrally. I also like the fact that the sensor code was written to include this functionality, and I'd like to take advantage of the well written code published by mysensors... Any help would be greatly appreciated.

@kunall said: @Tango2 Here is a tutorial for that. Hope that helps I'm getting closer.... I have my r-pi2 now, and I'm building openhab on there. I also got my dupont cables I ordered to connect my nRF24L01's up. I now have the r-pi and arduino uno (gateway) connected and wired up. Part of the problem I was having before must have been with VMWare ESXI, because now openhab sees my Arduino, however it only sees it on ttyACM0, not ttyUSB99 like it should based on the tutorial above. Should I change the syslink to ttyACM99? The tutorial doesn't specify, and my linux skills are far from good enough to know this off hand. I appreciate the help and look forward to setting some of these sensors up! EDIT: I did change the demo.items from the link that kunall posted above to reflect ttyACM0, and received the "0;0;3;0;14;Gateway startup complete." message, so I'm making progress, however I'd like to get the static assignment working for stability down the road.
