Describe the issue

when running the power-metering docker-container, I sometimes get:

Traceback (most recent call last):
  File "/app/measure.py", line 333, in <module>
    main()
  File "/app/measure.py", line 325, in main

    return PowerMeasurementResult(float(state.state), last_updated)
                                  ^^^^^^^^^^^^^^^^^^
ValueError: could not convert string to float: 'unavailable'

It would be good, if this would be caught and it would be tried again to read the sensor

Reproduction steps

run the container as documented
select a light
run

Error comes from time to time.

Thanks for reporting. I will have a look into fixing this. A bit strange why your powermeter is getting unavailable, I don't have that with any of my shelly's. Probably bad wifi reception.

Fixed with #1985 will be in next version.
