So, here is the status right now.
The section signal is read using a PC817 optocoupler board and ESP32 is running my MTZ forked code which connect to my mobile hotspot and does UDP with AOG v.5.7.2
I’m using a 16relay board because I need 2 relay for each section (reverse polarity) and there are 7 sections. I will add another additional PC817 board after the relay in order to send GND signal to the rate computer when sections are open.
I have also 3D printed a box that will fits between the müller boxes and which contains leds for real section status (relay output) and the man/auto switch. This boxes will just forward signal between müller boxes except section signals that will be coming from relays status.
