Hardware Development

​This project stems from the need to bring Hisense heat pumps into Home Assistant, addressing the absence of an official solution. It required over a year of work, from reverse engineering the protocol to developing a controller that guarantees stability and safety.

We chose the Open Source path. ​The decoded protocol specifications are fully documented and available on GitHub, ensuring transparency and allowing the community to contribute.

FAQ

Which models are compatible ?

The controller has been tested on AHZ-080CDS1 models. All Hi-Therma series heat pumps are supported experimentally. If you are still unsure, feel free to contact us here.

Do I need an Hisense Hi-Mit II interface for it to work ?

No, the device is fully standalone. No additional hardware is required.

Is the power adapter included ?

No, any standard USB power supply with a USB-C connector will work.

I already have an Hisense Hi-Mit II interface, do I need to remove it  ?

No, the HBS Bridge controller can share the same communication bus with other devices without causing conflicts.

How to wire the controller ?

The HBS Bridge must be connected to the H-Net transmission interface present on the machine. The bus is found on contacts 1 and 2 on terminal block TB2 or TB4.

How to update the firmware ?

Firmware updates automatically whenever a new revision is released.

Do I need Home Assistant for it to work ?

Not necessarily. Even though it's recommended, the device supports MQTT Autodiscovery and works with any broker. More info here.
