Bluetooth Low Energy
Please note!
Currently, the BLE proxy for SMLIGHT SLZB integration is under development on Home Assistant side and BLE proxy support is expected in the 2026.8 HA release. Therefore, by activating "Proxy advertisements" now, you will not start receiving BLE notifications inside HA until you update HA to 2026.8 release.
General information
SLZB-OS supports receiving BLE advertisements for U series and Ultima devices (ESP32-S3 devices).
Active BLE connections are not supported.
Only support passive/active scanning.
The system consists of two parts:
- SLZB-OS with "Proxy advertisements" enabled. Responsible for physically receiving BLE packets and sending them to HA.
- SMLIGHT SLZB Home Assistant integration. Manages scanning on the SLZB-OS side, receives raw BLE and forwards them to the HA core.
BLE proxy
BLE proxy uses port 5050 so please make sure it is not blocked on your network!
SLZB-OS supports proxying BLE packets to Home Assistant using optimized UDP protocol.
To use BLE proxy you need:
- Have SLZB-OS v3.3.3.dev7 or later
- Have Home Assistant 2026.8 or later
- Have active SMLIGHT SLZB integration
- Have "BLE" and "Proxy advertisements" enabled in SLZB-OS
