I was able to link my Sonoff TRVs with my iHost without any fuss and can control them through it. So the basics for TRV control are working!
Also adding them to scenes was effortless.
What is missing though is linking external sensors to them. I haven’t found a way to set external temp sensors or door/window-open sensors as primary sensors for the TRVs.
Through NodeRed this shouldn’t be a problem, but as iHost is made to be a user friendly all-in-1 solution, this should be added to the TRV-settings.
But for a first iteration of new system integration into iHost I’m positively surprised.
