Need some help pls in setting up/installing WIFI Thermostat to my BAXI 105HE combi boiler. I am already using Honeywell CMT927 Wireless Room Thermostat for last few years which is quite convenient so far. Now want to control the heating from smart phone. What sort of wifi thermostat (Honeywell, Heatmiser, etc) you guys can suggest which can work along the existing wireless thermostat and baxi 105 he combi boiler.
