Controlling an electric heater with a smart plug and room thermostat.

[MumMade]

We have a hub and TRV's and some rooms with thermostats controlling our oil heating and this works great. 
There is no heating in our conservatory and we have no insulated the roof and have an electric heater out there. Though if we bought a smart plug and a room thermostat we could set a programme on the room thermostat and it could use the smart plug to turn the heater on and off when needed - but it seems this is not possible. 

Is this possible? and if not why not as seems it should be.

For now we just need to manually turn the heating on and off from the app (or programme of and on times) but cant control the temperature at all - so the heater stay

Absolutely agree;it would be so useful if the Smart Plug could be controlled by a Wiser Roomstat.

Actually, it would be great to control also the Power Micro Module with a thermostat if the module is declared as Radiator or Under Floor heating.

You could wire the heater with a Wiser HeatingActuator and that can be controlled with/via a wiser room stat. However, this is a expensive way to solve your issue. If you are running Home assistant, you could set up a schedule and link with the room stat (or a zigbee room thermometer) and just automate the switching on/off of the wiser (or any other smart home) plug. 

note, if you use the Heating Actuator, then you have to have a wiser room stat in the same room (as defined in the wiser configuration) as the actuator. What you effectively end up doing is emulating the wiser underfloor heating setup except with an electric radiator.  IMHO, for the type of issue that you have, it’s quite an expensive solution and there are alternatives with third parties, however, if you want a solution that is integrated with the wiser app, then the Heating Actuator/Room Stat combination is the way to go.

ps, the heating actuator is a wired solution (ie, it does not just plug in - you would have to make up an extension cable with the actuator or wire it in ahead of an outlet - you may need the assistance of an electrician).

Thanks for your post. Special thanks to @DrJohnM, it is the right way to control an electric heater.
