I am trying this solution;

I am unsure on what to do with the timestamp. Should I use it to see which entity triggered it? My ultimate goal is to avoid having per room automations. but instead house wide automations

[merry python]

Make a template sensor with that template

You can make it in the UI

[pale thorn]

We canmake tempalte sensors in the UI now?!

Damn nice.

Ok let me do that

Done

Yep, now every time one of those media players change, it should trigger

[pale thorn]

Yes; And how do I know which entity triggered it?

[merry python]

well that's a different story

[pale thorn]

Haha

[merry python]

but you can use the same template to get the last changed

[pale thorn]

Could I use an attribute on the sensor?

I have something like that here:

      - name: "amount friends home"
        unique_id: "amount_friends_home"
        state: >-
             {# Set friendshome to the amount of friends #}
             {% set friendshome = states('sensor.guest_wifi_count') | int - states('sensor.amount_partners_home') | int  %}
             {{friendshome}}
        unit_of_measurement: "friends"
        attributes:
          friends: >
            {% set ns = namespace(friends=[]) %}
            {% for device_tracker in states.device_tracker | selectattr('state','eq','home')  | selectattr('entity_id','search',"phone_") %}
             {% if  state_attr(device_tracker.entity_id, "essid") == "Chilling Hotspot" %}
               {% set name  = device_tracker.entity_id | replace('device_tracker.phone_','') | replace('_',' ') | capitalize  %}
              {% set ns.friends = ns.friends  + [name] %}
             {% endif %}
            {% endfor %}```

[merry python]

you can, but that's only possible in yaml template sensors

[pale thorn]

Gotcha, I shall continue using that

I have this, but it relies heavely on states.* Is that bad?

[merry python]

no, it's just throttled to at most 1 update per second

the template itself

see the most recent pin in #templates-archived

Looks good, last question that I can think of. Can i get it to only update on state change? instead of every second?

[merry python]

it doesn't update every second, only state changes

it's a trottle

[pale thorn]

Oh, then maybe it's cause I got speakers buffering. I'll make one for speakers and one for chromecats

[merry python]

your last_changed, shouldn't be changing state

and if you're choosing the most recent playing one, it should be good

just make sure that you're getting the newest timestamp, not the oldest

[pale thorn]

Gotcha,t hanks Petro!

[merry python]

np

I think I got it working!
