Bluetooth Low Energy

Please note!
Currently, the BLE proxy for SMLIGHT SLZB is under development and has not been merged into the Home Assistant core. Therefore, by activating "Proxy advertisements" now, you will not start receiving BLE notifications in HA.
Please follow this PR to be informed when the BLE proxy will be added on the HA side https://github.com/home-assistant/core/pull/174710

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. Manages scanning on the SLZB-OS side, receives raw BLE and forwards them to the HA core.

BLE proxy uses port 5050 so please make sure it is not blocked on your network!

1. Have v3.3.3.dev7 or later
2. Have Home Assistant with SMLIGHT BLE Proxy support
