Im trying to create a sensor using the template assistant, to give me a % range left for my vehicle. In the state template section, I have added:
sensor.volvo_yv12zem10rs081866_distance_to_empty_battery/217
where 217 is the total range, but I get the error:
Sensor None has device class ‘None’, state class ‘None’ unit ‘%’ and suggested precision ‘None’ thus indicating it has a numeric value; however, it has the non-numeric value: ‘sensor.volvo_yv12zem10rs081866_distance_to_empty_battery/217’ (<class ‘str’>)
any idea how I can rectify this to return a % value?
