Thank you! That worked. Should have tried that...

I made a night light for my son and just used V_VARs I used the fastLED library And this code to decode from 255,255,255 that I was sending from the controller https://codebender.cc/sketch:90239 Last time it came up http://forum.mysensors.org/topic/1148/need-help-with-turning-a-led-on-off-with-openhab-and-mqtt/4

Yes, sorry. Baud rate is indeed 115200 and not 115600. I'll have to check Domoticz to see if I can change those values. I would expect others to have the same problem if those were set incorrectly. I seem to be the only one.

Thanks. Didn't know I had to secure that at the Domoticz end. Got it.
