Hi everyone,
I’m Alessio, and I’ve been working for more than a year on integrating Hisense Hi-Therma heat pumps with Home Assistant. The result is HBS Bridge: a small local controller that connects to the Hisense H-Net bus and exposes the heat pump to Home Assistant through MQTT autodiscovery.
What it does:
- local control, no cloud dependency
- MQTT autodiscovery for Home Assistant
- mode, zones and DHW setpoint control
- temperature and diagnostic readings
- OTA firmware updates
I originally built it because there was no official Home Assistant integration for these units. The protocol work is documented here:
Project/product page:
The controller has been tested on AHZ-080CDS1. Other Hi-Therma models should be compatible, but I’m especially interested in feedback from owners of different units.
This is a small hardware batch, so yes, units are available for purchase, but I’m mainly posting here to share the project, get feedback, and find other Hisense Hi-Therma users willing to test compatibility.
