Low battery level detection & notification for all battery sensors

Blueprints Exchange

very nice thank you!
is it possible to know which entity/sensor is having the low battery so i can send that as part of my notification message? i tried {{trigger.to_state.name}} but that didnt work.

I have previously used individual triggers per device so i had a notification like this: A device has low battery level 20% - {{trigger.to_state.name}}

EDIT: {{sensors}} works in the notification message to show which device has the low battery.

You need to add an action at the bottom and it should go away. The action can be a notification for a phone as an example

Do we have an INCLUDE instead / in addition to an EXCLUDE option meanwhile?!?

Did something change in HA? I am no longer seeing any of the devices in my notifications? My notification portion of the code.

alias: Batteries Warning

use_blueprint:
  path: dadge/low-battery-level-detection-notification-for-all-battery-sensors.yaml
  input:
    actions:
      - data:
          message: A battery in the sensor named {{sensors}} is reporting a low state.
        action: notify.mobile_app_pixel_9_pro_xl
      - data:
          message: A battery in the sensor named {{sensors}} is reporting a low state.
        action: notify.persistent_notification
    last_seen: 1
    time: "06:00:00"
    threshold: 50

In trace I see:

Triggered by the time at November 5, 2025 at 4:35:00 AM
Test If template renders a value equal to true
Stopped because a condition failed at November 5, 2025 at 4:35:00 AM (runtime: 0.05 seconds)

I had changed the time to watch when it triggers. Not sure why it is failing now. I have used this blueprint for a long time.

Thanks.
