I have just installed a Max system, 17 TRV's, 4 Room stats and a cube. I also have a Danfoss wireless stat for controlling the boiler. I was wondering how to get boiler control with the Max because currently the boiler runs all day. I then found your project. It looks a bit advanced for me though. I was thinking of using a Sonoff device just so I could switch the boiler on/off at my leisure for a quick fix. I have never used a RPi before. I see you have now changed to an Evo system was the Max that unreliable?
