Floor Heating Control

Options
Hi, I am planning to replace my current manual thermostat (radiator thermostat) for my floor heating with Tado TRV

Current installation
1. MMA Radiator thermostat with external capillary temp sensor
2. The radiator Thermostat is mounted in a closet that is warmer than room temp as furnace is located in closet.
3. The capillary sensor measures the temp of the return water and thereby has nothing todo with room temp (unfortunately) but it do make sure the water in the system doesn’t get to high to protect floor.

Planned replacement
1. Replace closet radiator thermostat with a Tado smart TRV
2. Add a Tado wireless temp sensor so I can by pass the temp measurement in the hot closet and make it control based on room temp.

Questions
1. Will above set up work as I think it will, I mean will the TRV regulate based on room temperature measured by Tado wireless temperature sensor?
2. Do I need anything more, I guess only the bridge to get all access?
3. As I want to protect the floor against to hot water temp, is there away to limit the water temp?

Thanks
