Xiaomi Smoke detector not working

Hi ! I just buy a new Xiaomi Smoke Detector. I had it into the app and it “magically” appear into the PAPERUI so I add the thing but it stay at UNINITIALIZED - HANDLER_REGISTERING_ERROR XiaomiHandlerFactory could not create a handler for the thing ‘mihome:smoke:158d000XXXXXXX’

So I try to add it manually in my thing file with the same ID

Bridge mihome:bridge:34ce00fa706c “Xiaomi Gateway” [ serialNumber=“34ce00fa706c”, ipAddress=“”, port=9898, key=“956038DA592A451A”, pollingInterval=6000 ] {
Thing mihome:gateway:34ce00fa706c “Xiaomi Mi Smart Home Gateway” [itemId=“34ce00fa706c”]
Thing mihome:fire_sensor:158d0001bba1d6 “Xiaomi Fire Sensor” [itemId=“158d0001bba1d6”]}

then add the item

Number Xiaomi_SmokeDetector_berging_Battery “Battery level smoke berging” { channel=“mihome:fire_sensor:smoke_berging:batteryLevel” }

But the status stay to “NULL”

I don’t know what else to try … how can I be sure of the device id ?

P.s My gateway is in 4.7.7
