Trigger to/from attribute

Configuration
1

I have an automation in Node red that does what I want, but I need something similar in HA automation.
I just can’t figure out the correct syntax.

msg.BTtrigger = "false";
if(msg.data.old_state.attributes.connected_paired_devices.includes("4E:C3:9E:5B:9C:86")){
    if(!msg.data.new_state.attributes.connected_paired_devices.includes("4E:C3:9E:5B:9C:86")){
        msg.BTtrigger = "true";
    }else{
        msg.BTtrigger = "false";
    }
}
//4E:C3:9E:5B:9C:86
return msg;

Check if the entity sensor.andreas_bluetooth_connection has been connected to one specific device and it now is not connected to the said device.

Anyone that can help me with that.

You’re looking for this. Specifically, an automation like this:

trigger:
  platform: state
  entity_id: sensor.andreas_bluetooth_connection
  attribute: connected_paired_devices
condition:
  - "{{ '4E:C3:9E:5B:9C:86' in trigger.from_state.attributes.connected_paired_devices }}"
  - "{{ not '4E:C3:9E:5B:9C:86' in trigger.to_state.attributes.connected_paired_devices }}"
action:
  ...Do Stuff...

No wonder why I couldn’t find it, it’s not even mentioned in the docs how to use attributes with trigger.to/from.

Is where any way to make it completely a trigger?
The automation I want to run this in also has a numeric state trigger, and if that part triggers then this condition will not be true.
Or could I make a sensor with the template from → to that I could make as the trigger?

to_state and from_state are state objects, which are documented at the link there. It would be easier to build a working automation if you share what you already have.

I don’t have much yet. I only have a problem :slight_smile:

The situation is that when I arrive home by car my phone is in high accuracy mode until I have walked far enough from the car that bluetooth does not reach.
Then it disables the high accuracy mode and I stay on the parking and never arrive home.
I want to maintain the high accuracy mode until I have connected to the wifi at home because I want to see if I can use my proximity to open the door by adding a ESP inside the intercom phone (the ones you have in apartment houses to open the front door).

At first I thought I could have proximity < 150 m only.
But because I park my car less than 150 m away then bluetooth will disable high accuracy mode.

If I set proximity 50 m then it won’t work either since it doesn’t seem to update my position with that small difference and thus does not enable high accuracy mode.

So my current plan is to have trigger 150 m and bluetooth disconnect, and have proximity 150 m as condition so that it doesn’t enable high accuracy mode each time I walk away from my car.

alias: Andreas high accuracy walking home
description: ''
trigger:
  - platform: numeric_state
    entity_id: proximity.home
    below: '150'
condition:
  - condition: state
    entity_id: sensor.andreas_wifi_bssid
    state: <not connected>
  - condition: numeric_state
    entity_id: proximity.home
    below: '150'
action:
  - service: notify.mobile_app_andreas
    data:
      message: command_high_accuracy_mode
      title: turn_on
mode: single

And then I have one that disables high accuracy when I connect to wifi.

I think I figured out a way.
If I have both the numeric state as trigger and the bluetooth.
Then in coditions I have an or that is true either if the numeric has triggered or if the bluetooth has triggered.
