I just realized I’m not sure how to do that or if it’s even possible or if it’s a dumb question. I should know this…
EDIT: I can think of a very roundabout way where I have an automation that populates a hidden input_xxx which is then read by the template sensor state but I def don’t want to do that.
Not really sure what the use case is, but a template sensor is just a sensor and you can make an automation react to that as with all sensors.
I think I figured it out, or at least partly.
Template sensors can have an action section as well!
So you can do something like
- trigger:
...
action:
- service: blah
...
response_variable: response
sensor:
- unique_id: "..."
...
state: >-
{{ ...use the response somehow... }}
