Reliable Thermostat controlled by Tellstick Net

[atte]

I´m looking for a reliable, non-battery operated thermostat & on/off switch that would be compatible
with Tellstick Net. The application would be to turn the heat on/off and read the temerature remotely in a cabin. The temerature could be set locally in the
cabin on the thermostat. So far, searching the internet and forums,
I have not been able to find one. Anyone with a suggestion?

Of what i have seen all thermostats use 868 MHz never seen any on 433 MHz.

Any 868 brand and model you would recommend?

I'm looking for a reliable room thermostat that can operate autonomously in the first place and in addition to that I want to read the current temperature and set the thermostat remotely.

Haven't bought any yet as I then have to get something like a razberry to access z-wave but the danfoss living connect TRV looks quite nice. But it is battery operated.
