Abstract

This repository holds a Node Red flow which gives you a user friendly dashboard for local control of your Panasonic heatpump.

---

Introduction

You can connect your Panasonic heatpump to the default CZ-TAW1 module. Then you are locked in the Panasonic ecosystem depending on using the wallmounted controller or Aquarea Smart Cloud.

Alternatively you can connect and control your Panasonic heatpump locally with Heishamon. The heishamon board is created by Egyras. AWESOME job! Get one here: https://www.tindie.com/stores/thehognl/

I have chosen to use Node Red (=NR) as FrontEnd and automation platform. In this repository you will find out all about this Node Red flow.
