Hi,
trying to rewrite all my yams files to the format of:
message: >
Update {{ states('updater.updater') }} for Home Assistant is available,
check {{state_attr('updater.updater','release_notes'}} for the latest changes.
Im stuck with the sensor.last_boot:
{{states.sensor.last_boot.last_changed}}
would be rewritten like:
{{states('sensor.last_boot').last_changed}}
but that doesnt work, and the last_changed isnt an attribute so {{state_attr('sensor.last_boot','last_changed')}}
doesn’t work either.
How should this be done?
thx,
Marius
Correct, last_changed is a direct attribute of a state object, it’s not in the state object’s attributes attribute. You can’t use the states() function, because that returns the state object’s state attribute. And you can’t use state_attr() because that returns something from the state object’s attributes attribute. The only way to get at last_changed (and last_updated) is to use states.domain.object_id.last_changed. See State Object.

Thank you, lesson learned +1.
just for my reassurance/confirmation, can i write
{{states.sensor.xboxid.attributes["XboxOne Full"]}}
as
{{state_attr('sensor.xboxid',' '["XboxOne Full"]')}}
?
apostrophes are a bit awkward here?
Well, I don’t have any entities that have an attribute with a name that contains spaces as far as I know. But I would think that maybe you could write that this way:
{{state_attr('sensor.xboxid','XboxOne Full')}}
At least worth a try.
