Get device which triggered an automation or script and send a notification to it

1

Hi, I have a bunch of users registered in my Home Assistant and also some automations and scripts which send notifications. Right now I am using notification groups to send notifications to multiple devices. I am trying to find a way to send notifications just to the device which triggered the automation or script.

In case of an automation, there is the trigger.entity_id variable. But I can’t seem to send a notification to a device by its entitiy_id.

For scripts, I couldn’t find a way how to identify the device which triggered the script.

Is something like that possible in HomeAssistant?

Thank you in advance.

Look into context.user_id.

Thank you. I could find the notify service with this template

{{ states.person | selectattr('attributes.user_id', 'eq', context.user_id) | map(attribute='attributes.device_trackers') | first | map('replace', 'device_tracker.', 'notify.mobile_app_') | list }}

This template assumes that the device_tracker id and the notify service id have the same name at the end.

The template you shared is very helpful! How did you then dynamically call the service from an automation? That’s where I currently fail.
