EQ3 Radiator Valve controlled by an ESP

Hello everyone!

A few weeks ago I found these interesting instructions for controlling a radiator thermostat via ESP.

While the wiring is described in a way I can understand, I can’t find any information about the ESPhome configuration.

Unfortunately, there is no information about the author or any way to contact him.
:frowning:

Does anyone have any idea what the YAML of such a wired ESP should look like?

Many thanks for your ideas
and help!
