Struggling to connect a Mi Flora sensor (Failed to pair: org.bluez.Error.AuthenticationCanceled)

Configuration
1

I’m running into some problems getting the Mi Flora sensor connected.

The instructions (https://www.home-assistant.io/integrations/miflora/) are very basic and only tell you how to scan for the MAC address, but doesn’t give any steps to show how to pair/connect the device.

I’ve used the bluetoothctl command to scan for the device, and then attempt pairing/connecting, but i’m running into a AuthenticationCanceled error.

Here’s what i’ve done so far:

Is there anything i’m doing wrong here?

TIA.

2

Actually it seems the sensor doesn’t need to be paired/connected, i’ve just restarted HA and had a look at entities relating to the sensor and 5 of them are showing and returning data.

3

I’m having a similar situation.
A few days (and HA updates) ago everything was running okay. Then 1 MiFlora device stopped working (sensor data Unavailable) and one other stopped updating. Now all sensors are gone.

Is it still working for you? Any clue how to get them up again?
