This integration enables full(*) control and monitoring of Daikin AC units using the BRC1H series controller over Bluetooth.
It is a local-only integration, requiring no cloud or internet access.
(*) Core Home Assistant climate functions are supported. However, advanced Daikin features, such as master and secondary units, are not yet available.
This is an early release; both the integration and the underlying library (kadoma) are still in the early stages of development. Errors and crashes should be expected.
The code has been tested under challenging conditions—multiple units on a single Bluetooth controller, unstable connections, long distances to the unit, etc. Although it includes automatic recovery and reconnection fallbacks, units may still disconnect occasionally.
