If Tado allowed or even launched smart plugs to the range it would help when trying to adapt to systems where hard wiring of zone valves or other on off devices so that we do not have to use Amazon Alexa or Google Home to add these items. As an example my own system has three on off zone valves (HW,Downstairs Heat, Upstairs Heat). I switch the valves via Alexa routines. I am about to make my own switch using Tado smart radiator valve and momentary push button in a box to test this. Full heat switch will press, 5 degrees switch will release and switch power to a valve.
