pliant ember
I have a blueprint which selects a device, this works, but i need to filter the various entities inside the device as triggers for my automation and can't figure out how...
Tried to work it out in variables, but this didn't work.
variables: audiocontroller: !input ac_device volume_knob: >- {% for entity in device_entities(audiocontroller) -%} {%- if entity|regex_search("volume_knob") -%} {{- entity.entity_id -}} {%- endif -%} {%- endfor -%}
The device got 3 buttons, and a rotary decoder.

Try just using
{{device_entities(audiocontroller) | select('search', 'volume_knob') | list | first}}
You can't generate a yaml list from a template and have it work
pliant ember
same issue... it's almost like the list of entities is empty, but the device is having those sensors...
and can't find (the right) documentation about blueprints. 😦 so it's a bit of a struggle to me.
hexed pollen
It's a single line template so needs double quotes around it
pliant ember
nope...
This is the code. maybe that will help 😉
i import the device, device is giving 4 sensors
(if i get it for 1, i get it for all)
But as you can have multiple devices, the sensor names get a _1/2/3/4 appended
so i need to search i suppose
hexed pollen
What are the entity names for those?
pliant ember
default binary_sensor.play_pause, sensor.volume_knob, binary_sensor.next binary_sensor.previous
But having multiple devices, gives you this.
The device is to control audio volume for sonos speakers (or other media players) and as they are mounted to the wall, the controls on the speakers are unreachable. it works, despite my blueprint. (Also got a nfc reader inside to select playlists)
hexed pollen
Fair enough. Try using that template in developer tools
You'll be able to debug it easier there
pliant ember
in the dev template, it gives me [] if i do '{{ device_entities(xxxxx-my-device-id) }}'
hexed pollen
Are you sure you're using the right device id?
Try device_id('one of the entities')
pliant ember
nice, '' did the trick 🙈
pliant ember
so got it in a trigger var now, only need to link it to the entity_id as i got the name now.
hexed pollen
Aren't you returning the entity_id from that filtered list?
pliant ember
no, i got the name
hexed pollen
The device name?
hexed pollen
sensor.volume_knob is the id
pliant ember
hexed pollen
All the things returned by device_entities are ids
Why have you stripped the "sensor." from the start of that?
pliant ember
trigger_variables:
audiocontroller_id: !input ac_device
audiocontroller_entities: '{{ device_entities(audiocontroller_id) }}'
volume_knob: >
{{
audiocontroller_entities | selectattr(None, "search", "sensor.volume_knob*") | list | last
}}
trigger:
this is what i got now...
the trigger var seems to be filled
but the trigger says no
hexed pollen
Not selectattr... Just select
pliant ember
found: https://github.com/Blackymas/NSPanel_HA_Blueprint/blob/main/nspanel_blueprint.yaml which seems to do the same for relay_01
hexed pollen
Try just using
`{{device_entities(audiocontroller) | select('search', 'volume_k...
This
Also your regex shouldn't have a * at the end
That's just making the "b" optional to multiple so it will accept volume_knobbbbb and volume_kno
pliant ember
okay, if i put it in the dev tool, it still gives me a name, not an id.
with the select, no *
hexed pollen
That's the id
pliant ember
but why does it still give the error than?
hexed pollen
Entity ids are not gibberish uuid strings
pliant ember
i expected a is like the device id
hexed pollen
Because apparently that doesn't like having a template in
hexed pollen
Here you can see it hasn't rendered the template you've put in
hexed pollen
So it's working now?
hexed pollen
I don't know if you can use templates there, I think it unlikely
You might have to make a template trigger
pliant ember
looked at the nspanel blueprint, they do it the same.
hmm, not in the trigger part....
it once worked, about 2 years ago 😦 not sure when it got broken.
but var or trigger_var both won't work now
can make it a trigger on the device. no entity id.... with a extra step to get the right button
but conditions can't set ID's 😦
pliant ember
seems all i can do, is let the user select every entity instead of just 1 device 😦
In a blueprint i need to filter entities of a device, but how?
hexed pollen
Use a template trigger rather than a state one. That would be able to use your dynamic entity_id
pliant ember
will look into it tomorrow... thanks for your help!
need to see how i can make the template trigger react on a change in volume
hexed pollen
Tricky
pliant ember
yeah, converting a automation to a blueprint is actually rewriting everything 😦

For most things, device_id's can't use templates. A couple of exceptions, but you are best off using entity_id's only.
pliant ember
so people need to select 4 entities instead of 1 device? that doesn't make any sense. Home automation is about making things easier 😉
and variables would help, but seems not available in trigger, even the trigger variables...

pliant ember
the difference between automations and blueprints maybe? as i want to keep it simple for users. if you have multiple of the same devices and need to remember entity id's instead of device names (which can be set to a logical name)
and in the trigger, entity id would be enough, but that's the issue here, we can't get them from the input device as state trigger
