Try removing the quotes around true/false.

Hi, @PeterSch - Welcome to the community! I’m not familiar with this particular sensor. Did removing the quotes as @Burningstone suggested work? If that’s not it, then take a look at the sensor contents within the developer/states panel and let us know what’s in there. All the attributes will be listed on the right side of the table. I’m looking for the actual names of the attributes and some of the values. If they are really booleans, then @Burningstone’s suggestion is spot-on and is the solution.

For future efforts, HA distinguishes between a boolean and a string that, on the surface, may look the same. For example,

true is NOT the same as 'true'
 ^                        ^
This is                 This is a
boolean                   string

These are not the same. The easiest way I’ve found to figure it out is using the developer/states page to see what’s really inside the sensor.

But I’m pretty sure @Burningstone nailed it.

Hi,

Thanks for the responses.
I have tried this, but no affect.
It looks like the value of attribute sensor.daylight cannot be used for state change?

try

trigger:
  - platform: template
    value_template: '{{ state_attr("sensor.daylight", "daylight") == false }}'
#6

Let us know if this works - this is an odd one. If it does, then that suggests the attribute never goes from true to false. It may go from something else to false (??), but the value_template should trigger in either case.

I should have asked this in the first place - are there any relevant errors or warnings in the log?

One other thought - with @cloak’s suggestion, you can test it out in the developer/template panel. Just copy the information within the braces (including the braces but not the single quotes) to the template test section and see what it provides. You can interrogate other attributes in this way, too.
