Template Sensor to check how many lights are on 2025

Configuration
12

Well, you could yes.

It will make it a 1 liner.

And yes, label light would do it . You can add more, like inside outside, whatever.

And make easy templates :wink:

{{label_entities('light')
             |select('is_state','on')|list|count}}

or

{{union(label_entities('binnen_lamp'),label_entities('buiten_lamp'))
|select('is_state','on')|list|count}}

which was done previously like:

{{['binnen_lamp','buiten_lamp']
   |map('label_entities')
   |sum(start=[])
   |select('is_state','on')
   |list|count}}

still works of course :wink:
