Home Assistant add-on repository for the Smart-G4 / S-BUS smart home system.

1. Settings → Add-ons → Add-on Store → ⋮ → Repositories and add: https://github.com/Alexa-RR/smartg4-addons
2. Install Smart-G4 Builder and start it — it opens from the HA sidebar (ingress).

Program and monitor your S-BUS installation without the vendor software:

• Device grid — live bus discovery with on-bus names, online status and per-channel state; rename modules (written to the device itself).
• Channel control — switch/dim any relay or dimmer channel.
• Flash backup — back up any module to a vendor-compatible .sbd file under /share/smartg4.
• DDP button programmer — decode a panel's real button configuration from its backup (labels + Magic-Line command lists), edit it, and test commands live. Flash writes are experimental and disabled unless the enable_flash_write option is turned on — keep fresh backups.
• Bus monitor — live decoded telegram console.
