Controlling hot water heater
I installed smart radiator thermostats in my holiday home. Mainly to turn on heating some hours before arrival.
I use central(District) heating for both radiators and hot water.
I would also like to turn on the hot water heater using the App and the extension module, but i learned that its not possible to use the extension module just as a simple on/off control unit to control a valve .
Off course the best solution would be a controllable unit with a cable sensor.
What can I do ?
ps. Im really looking forward to a All on / All off button in the App.
