From the project

a central camper van control system for ModBus in c#

The MQTT LED Dimmer is an ESP32-based 8-channel PWM LED controller that integrates with the VanDaemon control system via MQTT. It supports multiple devices on the network, automatic discovery, and real-time state synchronization.

- 8-Channel PWM Control: Individual brightness control (0-255) for each channel - MQTT Communication: Bidirectional control and state reporting - WiFi Configuration: Captive portal setup via WiFiManager - Auto-Discovery: Automatic device registration in VanDaemon - State Persistence: NVS storage for channel states across reboots - Status LED: WS2812 RGB LED for…
