Controlling a shower mix valve with Home Assistant?

Solving the mechanical problem is simple. I could design a housing that connects to the front of the already existing valve containing a servo which would turn the mix cartridge and away we go. Add a temperature sensor to the water flow and we have a way to dial in a temperature…etc.

But what about the already existing, overpriced digital valves that are on the market, like the U by Moen.

Do we have a way to connect and integrate those products or others like it?

did you ever find a solution to using the U by moen in home assistant

The only thing I’ve seen is this, which isn’t that.
