I don’t use LWRF for heating so am not plugging the system. I have no affiliation with Response Electronics but have encountered very good service from them in the past as a customer.
Running RFXCom with Domoticz on raspberry pi3. LWRF dimmer switches, PIRs and plug sockets. Some Homeeasy switches, harmony hub controlling AV and air con. Geofencing with Pilot app. Tado for heating and cooling.
