Add an option to select the power attribute

[Superpiffer]

I have unwanted and useless triggers with no power from appliances:

I analized some of this events and figured that the automation is triggered by "linkquality" attribute:

appliance_socket: switch.smart_plug_washing_machine
appliance_suspended_sensor: []
delayed_job_completion_duration: 0
delayed_job_completion_timer: timer.washing_machine_delayed_job_completion_timer
this:
  entity_id: automation.notifications_washing_machine
  state: 'on'

Is it possible to add a selection for the power attribute? For now I solved manually adding this:

trigger:
- platform: state
  entity_id: !input appliance_power_sensor
  id: power_event
  attribute: power
- platform: state
  entity_id: !input appliance_socket
  id: socket_state_change_event
  attribute: power

Hey @Superpiffer! Sorry for the late reply man. I see where the problem is, thank you for sharing it. However, I don't think that adding a select attribute would benefit everyone because most people (I'm one of them) don't have any attribute for such sensor.

The way you worked around this problem is correct, but I'm still wondering if we can have some kind of selection box to enable or disable this optional field.

I need to experiment but I don't know how to test it yet. Anyway, even if I added support to an attribute selection, it wouldn't be possible for the user to have some kind of dropdown choice selection, because it's facultative and so it would involve asking the user which attribute to follow and manually insert it in a text box. I think it's the maximum we can achieve for now.
