From the HA Docs:
- ESPHome
- Bluetooth advertisement listening: ESPHome ESP32 device with firmware 2022.8.2 or later
- Bluetooth advertisement bundling: ESPHome ESP32 device with firmware 2023.6.0 or later
- Single active connection: ESPHome ESP32 device with firmware 2022.9.3 or later
- Multiple active connections: ESPHome ESP32 device with firmware 2022.11.0 or later
- Shelly
- Bluetooth advertisement listening: Shelly v2 device with firmware 12.0 or later
- Bluetooth advertisement bundling: Shelly v2 device with firmware 12.0 or later
- Single active connection: not supported

Is the “Bluetooth advertisement listening” the Passive option under Configure of Shelly Integration and “Bluetooth advertisement bundling” the Active option?
Bonus question: Do you need active connections to control BT devices like locks, lamps etc.?
