OpenTherm with Remeha Tzerra Ace CW4 28C and Tado V3+

I have a Remeha Tzerra Ace CW4 28C boiler and the Tado V3+. I'm not sure how to check, but pretty sure I don't have it connected via OpenTherm.

Question is, is there any way to check what mode the Tado is running in?

Also, what benefits would I get to switch to OpenTherm?
