Heating Boost activated by IFTTT battery PIR sensor
We use convectors for heating. we suggest an applet whereby Having the heating on a standby setting with a set back temperature which could be boosted to comfort setting for a predetermined period using the' Boost' when presence in a room is detected from a smart PIR. As people remain detected then the boost is extended until such time as no presence is determined. Boost might run on for say a 30 mins run time.
