Dual zone Opentherm

Just moved into a new build and the set up is:

- Logic esp1 30 combi boiler

- 2X wired TPone M thermostats (one upstairs and one downstairs) they're two separate zones (downstairs and upstairs)

- Danfoss wiring box which runs into two zone valves

I want to setup Dual zone Opentherm and was thinking of buying the EU wireless version for the ground floor then keeping installing a wired start for the top floor to acc as on/off.

Would this work? At the moment i'm confused to how the top floor stat would work as on/off once OT has been wired in on the boiler and room/stat was been removed?
