@mkj that's the reason why I'm revamping it. I created it in 2009/2010 as I needed to find a way to turn on heathers before getting back home from long trips. So it was ssh only and simple. In 2012 it went into a Raspberry Pi inside the wall, and a nice led indicated the status. When I sold that house, in 2015 and moved, I started to use a Netatmo device - which is still running fine - as that setup would have been too complex here. But it's time to give it a new life.
