Description

MaxxFan Controller for Home Assistant

The MaxxFan is a great ventilation solution for RVs, but it lacks smart home capabilities. This controller bridges that gap by emulating the wall-mount remote control interface through an RJ-45 connection, bringing smart automation to your RV ventilation system.

Features:

Full control over MaxxFan operations:
Power on/off
Hood open/close
Air direction (intake/exhaust)
Fan speed control (10-100%)
Seamless Home Assistant integration
Simple RJ-45 connection to existing MaxxFan system

The ESPhome YAML, code, and Fusion360 Files are in the linked GitHub Repo.
