This is exactly what I am looking for i think! Since I have oenhab 1.8 running on my VM (gentoo) and mosquito runnin already. ( right now I use mqtt with kodi to to dim lights to my insteon switch when a movie starts) So I know mqtt is working. Now can I add my nR24L01+PA+LNA to one of my raspberry pi B or pi 3 or do I need another adriuno besides the nanos I already have build the gateway?
I starting out with motion sensors since I already had them orderd when I started this project. But I guess the mqtt client should be my first step
