Since 2024 i have been using this adapter which connects to the Mitsibushi Ecodan/Zubadan/Geodan Air-to-Water Heat Pump controller and provider over 120 entities of control and additional data into Home Assistant via MQTT (with auto-discovery).
The GitHub has loads of documentation on the features from simple to advanced.
It’s a great way to control your Ecodan locally and provide controls hidden by Mitsibushi.
Thanks for your comment, however i must correct you as your response is not quite true.
In fact, we are colleagues on this project - so i maintain the core discovery documentation from starting in 2023 for the Mitsi side and then worked together for nearly 2 years on this now while i first released 3 years ago.
Everything is open source, as per the link to github, exactly the same.
We have our own takes on things, and you mentioned the most advanced features for expert users. Released in the summer last year i did my onboard comp curve (bridging the gap to AA with Vaillant style) while Gekkekoe went full AA as an altrenative.
The core features are near identical as you say,
There is additional outdoor unit sensors, supporting Geodan and all sensors are working with proxy, support for dynamic entity generation which ESPHome can’t do
I don’t believe one is superior to the other, they are flavours of the same and each and presenting multiple options for users to choose between
I use this integration (hardware and software) to control my Ecodan R290 and I have to say it’s excellent. It’s very reliable and easy to easy to use for dashboarding and automation. F1p is very fast at responding to questions too. Thanks f1p.
but this project seem to use A LOT of stuff from other people. Which is fine opensource and all.
