Control your Vallox ventilation system using an Arduino board

vallox-esp

Control your Vallox ventilation system using an arduino.

Introduction

This project extends the analog step switch VSS-P from Vallox, that is used to control a ventilation system like the 90 SC.

It uses an arduino board with code to create a 10 bit DAC (Digital-Analog-Converter).

This way it's possible to create voltages between 0 and 10V, which controls how fast the fans of the ventilation system run.

Dependencies

The hardware consists of an Arduino Nano with an attached ENC28J60 ethernet shield, so the dependencies are as follows:

• EthernetENC for ENC28J60 support.
• MQTT Client to connect using mqtt.

The dependencies can be installed using the library manager in the Arduino IDE.

Credits

This project is based on the idea of Gernot Hillier.
