Hello,
I ordered Xiaomi Honeywell smoke detector bluetooth out of AliExpress and instead of ZigBee I got Bluetooth one 
Is there a way to integrate it with Home Assistant?
If yes, I guess I can use the Bluetooth embedded into the Raspberry pi 
And how would you extend the BT range to a different floor? (Is there a way to âbring around BT signalâ?)
Thank you all
Hi Ivan,
I did not test the following, but maybe you can find guidance from
Cheers,
Guido
and to âextend BTâ to your other floor you may try to get an ESP32 device (couple of USD on AliExpress) and flash with ESPHome (now integral part of Home Assistant). This will make following connection:
smoke detector <âBTâ> ESP32 <âWiFiâ> Router/AP <â> Raspberry
Thank you @guidok
I have actually found the same project⊠already placed the order for the ESP32 looking forward to try it out!
Which project did You find!? Did You end up with success?
I have a ESP32 loaded with esp32_ble_tracker but donât know what the sensor info for this smoke detector actually is!
Hi Guidok, Is there a decent tutorial or guide that You are aware of to do the configuration? I have flashed my ESP32 and tried to auto discover the smoke detector and manually create it. I just dont seem to be able to get it to work. Was copying this example esphome-components/examples/ble_gateway at main · myhomeiot/esphome-components · GitHub
Hi JoWink, unfortunately I didnât come across a tutorial. Iâve been doing trial and error. Iâve mine (KlikAanKlikUit Smoke Detector) connected to HA via a Conbee II stick. But this is using Zigbee (not BT / BLE). This pretty easy connects and then has few attributes available in HA. My Conbee II stick (via USB to RPi4) is very close to the Smoke Detector.
Here is a part of my esp32 config file, that might be of use (with an example of another BLE device) in case you have a bluetooth version. You will need to get the mac address from the esp32 log file (when you see blue tooth tracker active) and then edit/update your esp32 file.

Worked for me. Thank you!!

Hi, does anyone know if the Xiaomi Honeywell Bluetooth smoke detectors work with the new native Bluetooth support in HA (presumably via Xiaomi BLE?) Thanks.
(Sorry for hijacking thread but seemed to be relatedâŠ)
Hey, could you explain what you did? HA discovers it (same model as yours), however there is only one entity.
Hi Attila,
Can you please send us how could you solve the smoke detector problem?
It is asking for a hexadecimal key.
Köszönöm Attila 
Any way of flashing these with esphome firmware and cutting them from the xiaomi cloud BS?
