Master Unit

Description

The Main Module is the essential central hub of your on-board electronics system. This powerful controller serves as the master of the SystemBus, bringing all your individual modules — from relay boards and PWM dimmers to smart battery monitors — together into one stable network. Thanks to seamless integration with Home Assistant via Wi-Fi or Ethernet, this module acts as the perfect translator between your physical camper hardware and your smart home dashboards.

Designed specifically for the harsh environment of a vehicle, it features robust voltage regulation, hardware protections, and industrial, vibration-resistant connectors. With the Main Module, you lay the foundation for a reliable, energy-efficient, and intelligent off-grid power grid.

Key Specifications:

Central SystemBus Interface: Direct interfaces to control and read out all your connected bus modules.

Home Assistant Ready: Native communication via MQTT or ESPHome for real-time dashboards and advanced automations.

Robust Power Circuit: Engineered to filter and stabilize the fluctuating voltages of a 12V automotive electrical system.

Compact & Industrial: Solid PCB design utilizing secure screw or push-in terminals.
