Wireless Temperature Sensor not turning heating off
I have V3+ thermostats on every radiator in the house apart from in one room where I have 3 rads with manual thermostats and the heating controlled by a V3+ Wireless Temperature Sensor. I have an internet bridge.
Last night we went to bed earlier than usual and I switched off all the smart thermostats and the Wireless Temperature Sensor on the app. However, the heating in the room controlled by the Wireless Temperature Sensor did not turn off, the radiators in that room remained on all night.
Any suggestions as to why this is and how I can prevent it? Would I be better off to install smart radiator stats in the room that currently has manual stats, and maybe dispense with the Wireless Temperature Sensor altogether?
Thanks
