Hi everyone, I’ve been diving into the world of MQTT integration for Mitsubishi HeatPumps and wanted to share my journey and findings. If you’ve ever wondered how to control your heat pump without relying on cloud services, this might be of interest to you!
I recently stumbled upon a GitHub repository that offers a library for ESP8266 to control Mitsubishi heat pumps via serial connection. The library is written in C++ and can be adapted for other microcontrollers with a serial port. The creator and contributors have done an amazing job, especially with the MQTT integration. They’ve developed sketches ranging from simple controls to full-fledged MQTT setups, which is fantastic for those looking to integrate with platforms like Home Assistant or openHab.
One of the standout features is the ability to send remote temperature data to the heat pump, which is particularly useful for attic-mounted ducted units. This functionality is currently in a test branch but is expected to move to the master soon. What’s even more impressive is that this setup allows for more control than what’s offered by MEL Cloud, KUMO Cloud, or MHK1 devices, all while keeping everything local and secure without cloud dependency.
For anyone interested, I encourage you to check out the GitHub link provided in the thread. It includes detailed documentation, schematics, and part links for ordering. This project not only enhances functionality but also adds a layer of security by eliminating the need for external cloud services.
If you’ve worked with similar setups or have any questions, I’d love to hear your thoughts! Let’s keep the conversation going and explore more ways to optimize our smart home setups.
Cheers,
