MOTORHOME CONTROL PANEL / ESP32 APPLICATION
Cbe Ds300 Esphome Panel
Replace the CBE PC-100/PC-200/PC220 motorhome panel with an ESP32-P4 10.1" ESPHome + LVGL touch screen on the CBE DS-300 (reverse-engineered connector 17)
About this project
About this project
A motorhome's failing CBE panel is replaced by a 10.1-inch ESP32-P4 touchscreen while the DS-300 distribution box stays untouched, the new panel plugging into the same cable. The valuable part is the reverse-engineered pinout: the main switch and the pump are switched by pulling their command lines to ground, with no pulses and no data protocol. Two relays driven through a PCF8574 sit on normally-closed contacts, so a dead panel leaves everything on; an ADS1115 reads the CBE temperature probes and the grey tank. Everything else comes from Home Assistant, and cutting the 12 V needs a PIN and a 90-second countdown so the Raspberry Pi shuts down first. The firmware is one ESPHome YAML file.
