Danfoss

&feature=youtu.be&w=600 I’ve been trying to take over control of my home’s central heating using a combination of software and commodity hardware such as the Arduino and Raspberry Pi. Part one of this series looked at how my existing RF thermostats worked and showed it should be possible to emulate them so that the receiver (which has relays that turn heating zones on/off) already connected to the boiler could be used by my own control system. I currently have two Danfoss TP7000-RF wireless thermostats (one per zone) and a Danfoss RX2 receiver. ...

I wanted to control my central heating system using a Raspberry Pi and Arduino micro-controllers to provide better control, flexibility, and a fun home automation project. We originally chose wireless thermostats when we replaced the heating system in our home, but their user interface is not great and they are fiddly to use. “Smart” thermostats were starting to come onto the market showing a glimpse of what could be done. ...
