First arrow: every now and then it crashes and loses the GPIO config.
Otherwise these read to me as normal messages?
I tried sending the on/off through serial as well, also no effect. Tried adding a group, also no effect.
Now this is interesting: after I tell it through serial to reboot it starts on off AND the light is off.
I can turn it on, but after that I can no longer turn it off :S.
I see the same if I do the reboot and "on" from MQTT.
So positive: it appears that it can control the relay to some extend. But how do I get it to turn off and how do I regain the ability to change the state?
