ESP32-S3 firmware for communication with Berner/Elatronic kitchen appliances. Control and monitoring of salamanders, cooking devices, warming cabinets via Modbus RTU with touch display.
Industrial kitchen appliances had no digital control interface. Settings had to be adjusted directly on each device, and centralized monitoring was not possible.
An ESP32-based touchscreen controller enables centralized operation and monitoring of up to 247 devices through a single display via Modbus RTU.
