Hi, Thank for your reply. Yes, i run since many years with a serial Gateway connected with my PI. I thought it was possible to use the same machine to remove this extra element. If you had a stability issue, I would just stick with my current formula and not change everything for now. Regards,

I never used HAAS but have you looked at this page for how to set initial state? Then you can just send that to the controller. https://www.mysensors.org/build/relay

@diltech glad to hear you found a way. Just a little note.. this is not a french forum ;)
