Entity sensor.smartdry_battery <ESPHome> is using native unit of measurement 'None' <snip> device class ('battery')

[KenKilty]

The problem

A possible false positive for an ESPHome device with what I believe is a proper configuration below, note the unit_of_measurement is '%' in the ESPHome YAML. Possible false positive?

sensor:
  - platform: template
    name: "SmartDry Temperature"
    device_class: 'temperature'
    unit_of_measurement: "°C"
    accuracy_decimals: 4
    id: temp_sensor
  - platform: template
    name: "SmartDry Humidity"
    device_class: 'humidity'
    unit_of_measurement: "%"

% is not a valid unit for signal strength. This error is correct

[tefracky]

I am using the code from the example and I have the same error: https://esphome.io/components/sensor/wifi_signal.html

Either your code or the documentation is wrong.

[heythisisnate]

FWIW I think that % is a valid unit for signal strength. Although not technically precise, it is a commonly approximated measurement because dBm stated as a negative number is difficult for many people to understand. WiFi signal strength on iOS and Android is commonly expressed in "bars" which in essence is a visual representation of percent.

Also the fact that this example in the ESPHome documentation is the source of (at least some) of the warning messages here.
