Usage of Inputs with PCP

[P1Rebo]

I bought the pre-built board by @Gifford47. It works very smooth by using MQTT!

Now I'd like to connect everything to my electric installation and the wall-mounted buttons. In my previous setting the Hörmann Supramatic 3 Garage Door was controlled via Relais signal to the Hörmann UAP.

Is there any way to reuse the signal for the pre-build board?

Many thanks in advance!
