Smart Ventilation - ValloPlus 350 SC L

About

This project extends the ValloPlus 350 ventilation system with a microcontroller in order to provide a smart remote control interface. It provides a HTTP based interface to control the fan-speed and to toggle the Bypass mode. The interface can be easily embedded in a smart home control setup like Home Assistant.
