Hi everyone, I wanted to share my recent success with integrating a Clivet thermodynamic water heater into my smart home setup. I’ve been working on this project for a while, and it’s finally up and running smoothly!
The device in question is the Clivet AQUA PLUS SWAN-2 190. After some research, I discovered that it’s essentially a rebranded Midea water heater, which was a fun surprise! The integration process involved connecting it to my Home Assistant platform using Modbus. I set up a custom integration that allows me to monitor and control the water heater through the platform.
The setup wasn’t without its challenges. The control board on the heater has a non-standard XHB2.54-3Y connector, which was a bit of a gotcha at first. I had to source the correct adapter from a Chinese retailer, but once that was sorted, everything fell into place. I also had to modify the firmware slightly to ensure compatibility with the ELFOCONTROL3 EVO module, which was a great learning experience.
The integration now supports around 30 entities, covering everything from temperature controls to diagnostic sensors. The README in my GitHub repo (linked below) goes into detail about each entity, so feel free to check it out if you’re interested. I’ve also included some tips on troubleshooting common issues, like ensuring the Modbus connection is stable.
One thing I found particularly interesting is how the Clivet device mirrors the Midea COMBO RSJA2-16/190S in terms of functionality and register layout. This means that the integration should work seamlessly for Midea users as well, which is a huge plus!
I’d like to give a shoutout to the Home Assistant community for their support and resources. Without the collective knowledge and willingness to share, this project wouldn’t have been possible. If anyone has questions or needs help with their own setup, please don’t hesitate to reach out!
To everyone out there working on similar projects, keep at it! The satisfaction of seeing everything come together is well worth the effort. Let me know if you’d like to collaborate or share your own success stories—I’d love to hear them!
