I’ve come across a number of open source projects aimed at home automation and smart heating control. The first I found is OpenRemote and then OpenHAB came along that offers even more flexibility. The new generation of smart controllers I mentioned in the welcome post have proprietary TRVs, but the OpenTRV project aims to bring control to individual radiators or zones. There’s also a project to control Heatmiser WiFi thermostats and a German one for Worcester’s Heatronic 3 system.
