[Solved] Looking for Thermostatic Head with External Radio Sensor for Accurate Room Temp

Hello
I wanted to automate the heating in the living room a bit.
I found something like the one in the picture:
.
You can set the temp during the day, at night, it has an open window sensor etc.
The problem is that the temperature sensor is mounted in the head and somehow I don't think that if I set 22 degrees in the living room I will have 22 degrees. After all, it's always warmer by the radiator, especially as the radiator is partly behind the sofa.
I would need something like this but with an external radio sensor. I mount the sensor on the wall and according to this sensor the head controls the temperature.
Unfortunately, digging around on google was of no use - electronic thermostatic heads do not come with an option for an external sensor - unless I have searched poorly and anyone has any interesting suggestions on how to remedy this?

Fibaro has such a head with an external sensor, except that (I think) it does not work autonomously.

Familiarise yourself with these systems:

If it doesn't work automatically then how would it work? I don't get it?

Interesting system but it's more for electric heaters. I don't really see how it would control a tetmostatic head on a traditional radiator.

Autonomously not automatically, i.e. without a Fibaro control panel it probably won't work, but I'm not 100% sure.

unky but this system works. You have to add a thermoelectric actuator to it.

Danfoss also has an interesting system... Link .

This Danfoss system and associated problems are described in this forum:

I finally purchased the head from the first post. A very cheap and simple solution and my fears that the temperature sensor is relatively close to the radiator have been allayed and it works really well. For a small amount of money you can have a nice heating automation in the rooms - day/night settings, boost mode, independent settings for different days of the week, etc. A really great solution. I recommend. If I was installing radiators in my flat today, I wouldn't use traditional thermostatic heads, but only electronic ones. I am still curious about the battery, but according to the description they should be sufficient for two years.
