homebridge-homematic

Requires mandatory pre-configuration of Homematic CCU subsections and port management (e.g., avoiding conflicts on ports 9090-9092), which can be daunting for users unfamiliar with both systems.

Custom service definitions in channel_config.json are overridden on plugin updates, forcing users to manually reapply changes in homematic_config.json, adding maintenance complexity.

Certain features like program control require an 'ios10' flag due to limitations in Apple's Home app, indicating integration hurdles and potential user confusion.

The README notes that too many devices can cause HomeKit connection failures, necessitating manual device filtering to maintain stability, which limits out-of-the-box scalability.
