Vaillant Efficiency

Helps to optimize duration of the cycle length of Vaillant heating units through ebusd.

! Important: this software is early alpha work-in-progress and not ready for production - USE AT YOUR OWN RISK !

This project is a private endeavour and not an official Vaillant project. It is not associated with Vaillant in any way.

Overview

I am developing this tool to fix some shortcomings of the Vaillant controller. In particular the controller faces problems during periods of warmer outside temperatures leading to very short heating cycle length of heat pumps etc.

I am developing this in my free time so there aren't any guarantees this will ever be ready for production or feature complete.

Environment and Dependencies

  • Recommended environment is a Debian (or one of its derivatives) Linux OS, e.g. Raspbian on Raspberry PI.
  • Packages node (18+), git, ebusd

Installation

  • Install required dependencies, make sure ebusctl is accessible by the user which runs this process
  • Clone this git repo
  • Run npm i && npm run build within the project's root

Configuration

  • Make a copy of file .env.example named .env (inside root folder of project), edit it and adapt its values to meet your setup

Running

node dist/controller.js
