Help with configuration heat control


I have installed a new home assistant on a nuc.
I got my sensors connected and the relay working from the dashboard.

My plan is to have one temp sensor in each room.
This sensor will control the heat zones as i use water heatet floor system.

How do i add a thermostat function where one temp sensor (zigbee) can control a relay (zone1) from the dashboard ha?

any guides would help?
