Smart thermostat that doesn’t rely on RF?

Hi,

Anyone know of a smart thermostat to control my oil boiler which also works with smart trv’s but doesn’t communicate between a hub and thermostat via radio?

I had an issue in my previous home with a garage combi boiler my nest couldn’t communicate with in the kitchen. My new house is weirdly long and i need the thermostat upstairs but the boiler is again in the garage.

i think Drayton wiser has a repeater i can buy to help but is there anything on the market which communicates purely over my home network to avoid this hassle?

 Thanks
