Hey I’m relatively new to Home Assistant - I’ve been experimenting and built a weather station of sorts.
But I need help formatting one of the sensor values - A UV safe exposure time sensor - the value is in minutes, generally 1000s… I’m in England and it’s winter. At night it reads “Unknown” as I guess there’s no data.
I’d like the value to be displayed as HH:MM
I think it should look something like this - but I’m kind of stumped:
sensor:
- platform: template
sensors:
skin_type_2_safe_exposure_time:
friendly_name: "UV Safe Exposure Time"
value_template: '{{ state_attr, timestamp_custom("%H:%M", 0) }}'
…and I guess that it would need to check if there’s a numerical and that the value of the sensor is not “unknown”?
Any help much appreciated!
