[Home Assistant] Get friendly name of the triggering device in an automation

In an automation, you can retrieve the friendly_name of the triggering device using:

{{ trigger.to_state.attributes.friendly_name }}

Helpful if an automation can be triggered by different devices (e.g. garage door 1 or garage door 2) and you want to send a notification that explicitly names the triggering device:

  - service: notify.ALL_DEVICES
    data:
      title: Garage open!
      message: >-
        {{ trigger.to_state.attributes.friendly_name }} is open

[JavaScript] Working with Promises in 2024

Since ES2024 there is a new way to create promises by using the withResolver function:

// ES 6 Via Constructor
const promise = new Promise((resolve, reject) => { }

// ES2024 Via factory function
const [promise, resolve, reject] = Promise.withResolver( )

Since ES2018 there is an additional handler called finally:

const promise = fetch("/myAPI")

promise
  .then(response => console.log(response))
  .catch(error => console.error(error))
  .finally(() => console.log("Called in any case"))

And handling multiple Promises has been made easier by the new methods allSettled, any, race which were introduced in ES2020 and ES2015:

// Promise that resolves when all promises are resolved
const promise = Promise.all([promiseA, promiseB])
promise.then(([valueA, valueB]) => console.log(valueA, valueB))

// ES2020 Promise that resolves when all promises are settled (either resolved or rejected)
const promise = Promise.allSettled([promiseA, promiseB])

// ES2020 Promise that resolves when either promiseA or promiseB is resolved
const promise = Promise.any([promiseA, promiseB])

// ES2015 Promise that resolves/rejects when any promise is resolved or rejected
const promise = Promise.race([promiseA, promiseB])

[Home Assistant] Zigbee2MQTT device_class motion is now occupancy

After the last Zigbee2MQTT update to version 1.39.0, suddenly the motion sensors were missing in my auto-entities cards, which I use to display all motions sensors for specific areas.

type: vertical-stack
title: Bewegungsmelder
cards:
  - type: custom:auto-entities
    card:
      show_header_toggle: false
      title: null
      type: entities
      state_color: true
    filter:
      include:
        - attributes:
            device_class: motion
          options:
            secondary_info: last-changed
          area: cellar
    sort:
      method: last_changed
      reverse: true

When checking the changes included in the new Zigbee2MQTT version, I found the reason: https://github.com/Koenkk/zigbee2mqtt/pull/22896
With this pull request, the device_class is motion is replaced with occupancy. After changing the device_class in the auto_entities config, the motions sensors are displayed again.

Alternatively, you can switch the device_class back to motion, like it is described here. This would also bring back the old icon mdi:motion-sensor instead of mdi:home-outline.

[Home Assistant] Send notification only when you are home or when you come home

If you have a notification, which is only relevant for you when you are at home, it does not make sense to send it, if you are away. Instead, it would make sense to receive it the moment you get home.

To do this, simply add an Wait for a template action before sending the notification, with the following content. This can be done via YAML configuration

  - wait_template: "{{ is_state('person.nico', 'home') }}"
    continue_on_timeout: true

or via the web interface

If you are currently at home, means the entity status is already in the state home, it will be resolved immediately, otherwise it will wait until your status changes to home.

[SAPUI5] Model binding events

this.getView().bindElement({
				path: sObjectPath,
				events: {
					dataRequested: (oEvent) => {}, // Executed when a request to server is send
					dataReceived: (oEvent) => {},  // Executed when data from server is received
					change:(oEvent) => {},         // Executed everytime you do ElementBinding
				}
			})

The events for dataRequested and dataReceived are only fired, when data is requested or data is received from a backend. This is not the case, when the requested data is already available in the model from a previous backend call. In such situations, the change event comes in handy.

The same can also be done via XML:

binding="{
  path: '/myEntitySet',
  events: {
    dataRequested: 'onDataRequested',
    dataReceived: 'onDataReceived',
    change: 'onDataChange'
  }
}"

[LineageOS] When someone calls, my own number is appended to the caller’s number

I had an issue with my Xiaomi Mi 8 phone, which really annoyed me. For some callers, my phone number was somehow appended to the caller’s phone number. This also meant that the number was not matched with my contacts. It looked like this:

When searching, I found a reddit post (as always) where someone had the exact same problem, even using the same phone. Therefore, I’m not sure if the issue is Phone or Lineage related.

https://www.reddit.com/r/LineageOS/comments/inud0m/incoming_calls_caller_id_issue

The suggested solution is to disable VoLTE. To be honest, I didn’t even know what VoLTE was exactly. After reading a bit, I found the required setting under: Settings → Network and Internet → SIM cards → 4G calls.
And fortunately, it also helped in my case. I could not really notice a difference regarding the phone quality, therefore I’m fine with it.
