Home Assistant

[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.
