ble_monitor: [Bug]: ValueError

What happened?

Lots of ValueError in the logs.

ValueError: Sensor sensor.ble_heart_rate_f5f5da96f7bc has device class 'None', state class 'measurement' unit 'bpm' and suggested precision '0' thus indicating it has a numeric value; however, it has the non-numeric value: 'unavailable' (<class 'str'>)

Already tried removing the integration, restart HA, install integration, restart HA.

Sensor type

No response

~~This is an bug in Home Assistant, please add your info in this issue~~

No, sorry, it is an issue in BLE monitor. A quote from on other issue

The problem is that modbus/sensor.py is extending RestoreEntity when it should instead extend RestoreSensor which stores the sensor’s native value instead of its state

I’ll look into it

Hi all. Sorry for my english, please) I had the same issue and that’s what i did to fix it.

Run 2 queries in SQLite Web Addon:

DELETE
FROM statistics_short_term 
WHERE  statistics_short_term.metadata_id
IN ( SELECT statistics_meta.id FROM statistics_meta WHERE statistics_meta.statistic_id LIKE "sensor.ble_humidity%")
AND statistics_short_term.mean > 100

DELETE
FROM statistics
WHERE  statistics.metadata_id
IN ( SELECT statistics_meta.id FROM statistics_meta WHERE statistics_meta.statistic_id LIKE "sensor.ble_humidity%")
AND statistics.mean > 100

Unchecked “Restore state after a restart”
Restarted BLE Low Energy Monitor

After this steps all percent symbols returned back

Update. Of course you have to replace “sensor.ble_humidity%” with your actually name

@miguelangel-nubla Thanks for the logs. I see that the errors in your log only happen during the restart of the scanning process. The HCI scanning is restarted every minute (default period). Somehow, RSSI measurements and measured power (both in dBm) fail during that period. Strangely, @xelemorf in #1209 is saying that he still has sensors without unit of measurements. I’m still a bit lost where things go wrong, as I don’t see any of these errors.
