This is the controller so far. It has the main door control buttonas well as buttons for the light and lock. I also included a PIR sensor since my original controller had one. The PIR on the original controler was flaky at best. I have also included a screenshot of my ESPHome configuration.

I measured with a volt meter across the red and white wires and I see a fluctuating 20/21 volts which I assume is partially the serial data transmission on the line. I am hoping I can just integrate a 5 volt regulator into my new wall controller and power it from that wire.

So I have my RATGDO board connected to my opener and working with Home Assistant. I noticed that some people, me being one of them, have trouble with their wall button messing with the connection to HomeAssistant. If I disconnect the wall button, everything works as expected. My solution for this was to design myself a new wall controller that uses a xiao ESP32C3 controller running ESPHome that communicates to Home Assistant and performs the relevant wall button actions in Home Assistant. The issue I have is that I have to find a way to power the new wall controller. Is it possible to connect the red and white wires that were connected to the original wall button to a regulator that I can use to siphon the power needed to run the ESP32 controller? I mean the wires powered the original wall button somehow, so it had to have supplied power in some fashion. Why not reuse the wiring if I can, right.
