For example all metrics with unit % match humidity.
This generate correct metrics like this
# HELP nut_ups_battery_charge sensor.nut_ups_battery_charge
# TYPE nut_ups_battery_charge gauge
nut_ups_battery_charge{entity="sensor.nut_ups_battery_charge",friendly_name="NUT UPS Battery Charge"} 98.0
nut_ups_battery_charge{entity="sensor.nut_ups_battery_charge_2",friendly_name="NUT UPS Battery Charge"} 97.0
* Export climate metrics to Prometheus.
This adds climate_state and temperature_c metrics for each climate
device.
* Add more climate states to state_as_number
* Added min and Events sensor types to prometheus
* Updated prometheus client and fixed invalid swith state
* Added metric to count number of times an automation is triggered
* Removed assumption that may not apply to everybody
* Fixed tests
* Updated requirements_test_all
* Fixed unit tests
Prometheus (https://prometheus.io/) is an open source metric and alerting
