Initial purchase and set up

Hi, I am just looking to install the Tado system to hopefully help with my energy usage and bills and to show where and when it is being used.

I have an air source heat pump system with underfloor heating downstairs and radiators upstairs.

Downstairs there are 4 zones with wired thermostats so this is easy enough to change to the Tado thermostats, but upstairs I have one portable thermostat and then all the rooms on TRV's.

Just wondering how to convert upstairs to the Tado TRV's
