Triggername in Notify?

[languid plaza]

How can I write here in the notification which device no longer has a battery, i.e. which device has triggered the automation?

description: ""
triggers:
  - type: battery_level
    device_id: xxx
    entity_id: xxx
    domain: sensor
    trigger: device
    below: 15
  - type: battery_level
    device_id: xxx
    entity_id: xxx
    domain: sensor
    trigger: device
    below: 15
conditions: []
actions:
  - action: notify.mobile_app_xxx_handy
    metadata: {}
    data:
      title: Battery empty
      message: <Friendly Device Name> must be loaded!!
mode: single

can you post your new automation code and also the trace?

Did this come up when you manually triggered it to test? Because yeah - in that case there isn't a trigger variable. Might also be the fault of the battery level trigger because ew (try to avoid using device triggers when possible)

You could also label the triggers (give them an id that corresponds to the entity id)

Or use a numeric state trigger instead, and then the trigger solution definitely does work

yes, make sense
