Use template in entity list in an automation?

[murmusbahnus (murmelbahn)]

Hi,
I have a simple automation which sends me a message to my phone when the battery_level of an entity is below 15. As trigger for this automation I have inserted a list of all the entities. Did someone know if i can template this entity list? All entities have “battery_level” in their name.

Here is the code for the automation:

- alias: 'Notify Battery'

  trigger:

    platform: numeric_state

    entity_id: sensor.hue_motion_sensor_wohnzimmer_battery_level,

               sensor.hue_motion_sensor_esszimmer_battery_level,

               sensor.motion_sensor_arbeitszimmer_battery_level,

               sensor.motion_sensor_schlafzimmer_battery_level,

               sensor.arbeitszimmer_dimm_battery_level,

               sensor.button_tim_battery_level,

               sensor.button_kitchen_battery_level,

               sensor.rechtes_fenster_schlafzimmer_battery_level,

               sensor.arbeitszimmer_tuer_battery_level,

               sensor.wc_guests_door_battery_level,

               sensor.lumi_sensor_smoke_battery_level,

               sensor.linkes_fenster_schlafzimmer_battery_level,

               sensor.wohnzimmer_dimm_battery_level,

               sensor.esszimer_fernbedienung_battery_level

    below: '15'

  action:

  - service: notify.ios_devices

    data_template:

        title: "Batterien"

        message: "{{ trigger.to_state.attributes.friendly_name }} benötigt eine neue Batterie!"

        data:

         push:

          thread-id: "Batterie"

  - service: persistent_notification.create

    data_template:

        title: Batterien

        message: "{{ trigger.to_state.attributes.friendly_name }} benötigt eine neue Batterie!"

        notification_id: Batterien

While not exactly what you’re looking for, personally, I use this custom auto-entities card for situations like this on my dashboard that shows instead of notifications/alerts - as they’re more ‘static’:

Auto-entities - Automatically fill cards with entities

Finally released in HACS. This lovelace plugin lets you automatically put entities into lovelace cards. You can e.g. make an entities card which shows all your remotes which have a low battery. Or a glance card which shows all lights that are currently on. There’s lots of matching options. Like selecting all media players where the currently playing song matches a regular expression. And you can also finally sort the entities! Here’s just some examples from my development setup: [local…

Yes I know the card, it is quite usefull but I need this “wildcarding” in an automation.

Does this help?

How to survive without the "ALL groups"

Update: Please also see @petro’s PSA: Turn on/off all lights in Home Assistant 0.104+ (group.all_* changes) for examples. I have noticed there is some concern about how to get along without the formerly automatically generated groups like group.all_lights. I promise you there is a way to make your code work without them. Ask here and we can help you. First off, the following is the correct way to turn off every light now. service: light.turn_off entity_id: all # replace group.all_lights with…

You appear to be using tabs for indentation. Home assistant will not like this. Use only spaces for indentation.

Oh okay, thank you for this. I will use this in the future:)
