Trigger-based sensor: is it reliable to listen to event_template_reloaded?

Configuration
1

A simple sensor:

template:
  - trigger:
      - platform: event
        event_type: event_template_reloaded
    sensor:
      - name: xxxx
        state: >-
          {{ ... }}

When templates are reloaded → the event_template_reloaded is generated.
Will the event be generated AFTER all templates are reloaded?

If no → then probably this particular sensor may not catch this event since it is STILL being reloaded.

My guess seems to be correct - found related threads here.
A template sensor MAY BE still being reloaded - and cannot catch this event.

I have an automation that listens for event_template_reloaded and all it does is fires another event mb_event_template_reloaded. Then other code listens for that event instead. It seems to work more reliably but ymmv.

Listening the “event_template_reloaded” in an automation is a different thing since automations are not reloaded when this event is generated.

Sorry, misread your post.
Hmmm, this is an interesting way.
Also, if you add a small delay in the automation BEFORE firing the custom event - it will work more reliable.

Btw, I may be was too quick with marking the thread “solved”.
Found this post where it was said that the “event is posted after Template entities are reloaded”.
But I am still observing this erratic issue.
