Setup

Connect ESP32 TX2 & RX2 to DI & RO of the Max485.

Connect ESP32 D23(or whatever read_line is set to) to RE/DE.

Power Max485 with ESP VIN/GND.

Replace {WIFI_SSID}, {WIFI_PKEY}, {MQTT_HOST}, and {MQTT_PORT} in the code(and SubTopic if you want).

Flash the code onto the ESP32, connect A&B of the smart cable connected to the controller(aka the black and red wires respectively) to the Max485.

Viewing the USB serial of the ESP32, send 0xAB-like hex sequences to update the configured state.

Known States:

All of the protocol reversing has been done with 1 brain & 1 controller, so any unique fields are constant and will need to be updated.
