Opentherm parameters visible

ypkdani

Hello,

i have a Remeha Tzerra M Boiler and i want to communicate in Opentherm with it. I have to control the heating valves too. I need so to connect the Tado with the valve and the Extension Kit to the boiler using the Opentherm port.

I need to buy the Extension kit but before that i want to understand what parameters i can manage with Tago though the Opentherm bus.

Normally the parameters accessible are a lot (image attached).

Thanks
