I am looking for thermostats for baseboard heaters. I am hoping, although not required, that the thermostat will look nice and display outside temp, room temp, set temp, humidity and the current time. Although I am willing to settle for room temp and set temp.
Ideally, the controls will be simple, with up and down arrows. Complex programming can be done via a smart interface.
It’s a cottage, so the power will be turned on and off. Settings can’t get lost during power outages etc.
I am hoping for a somewhat foolproof system, so the internet can not be required, and hopefully, the thermostats will continue to function, at least somewhat when wifi is down.
Since there is a thermostat in each room the price of the thermostats is an issue. There are many rooms and I don’t want to purchase an expensive unit for each room.
The thermostats should mount in existing single gang US wall boxes.
Some rooms currently have two thermostats that I would like to control together.
I have been looking at the following hardware:

I figure this could be mounted in the baseboards themselves, or perhaps fit into a wall box.
I figure a thermostat with a built-in relay might be best for reliability, but where multiple units are controlled together, (which may not have dedicated thermostats) perhaps a wifi capable relay could be used?
Any thoughts on the best hardware to achieve this?
Thanks
