Although they appear in Developer Tools/States, the script don’t work for them…
My battery state is not a sensor, but a attribute of a sensor. That’s why I didn’t work for you.
Maybe this is a solution: 🔋 Lovelace: Battery state card

Thank you. I’ll try to integrate it.
hi, how to fix this?
{{ states.sensor
| selectattr('attributes.device_class', 'defined')
| selectattr('attributes.device_class', 'eq', 'battery')
| selectattr('state', 'lt', 25) # <- this will not work: TypeError: '<' not supported between instances of 'str' and 'int'
| map(attribute='attributes.friendly_name' )
| list }}
