const.TEMP_FAHRENHEIT is "°F", but _unit_string converts this to "c",
so the comparison never succeeds and we end up with temperatures in F
but labeled C.
Giving a value of 0 by default can lead to erroneous
data being exported. For example, if a MQTT temperature
sensor is in `STATE_UNKNOWN` (which can happen after a
HASS restart), a temperature of 0°C will be exported.
Some user might prefer no value rather than a wrong one.
Referencing issue #26418.
Prometheus metric names can only contain chars a-zA-Z0-9, : and _
(https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels).
HA currently generates invalid prometheus names, e.g. if the unit for a
sensor is a non-ASCII character containing ° or μ. To resolve, we need
to sanitize the name before creating, replacing non-valid characters
with a valid representation. In this case, I've used
"u{unicode-hex-code}".
Also updated the test case to make sure that the ° case is handled.
* - Change how we extract the metrics for sensors
- Add component filtering as seen in influxdb
- Add metric override as seen in influxdb
- Add more unit tests with actual device data
* Extract sensor metric logic to separate handlers
* Update prometheus dependency
* Format using black
* Format using black
* Fix flake8
* Move sensor metric handler list to init
* Use f strings instead of .format
