Setting MQTT sensor hidden attributes

Configuration
1

Using an automation, I want to change the hidden attribute on a bunch MQTT sensors when I receive a payload from one of them. Using pushbullet to test my automation is triggering, but I’m having a hard time figuring out how to change the hidden attributes through an action. Here is what my pushbullet test…

- alias: 'apple is on'
  trigger:
    platform: mqtt
    topic: 'pis/apple/last-seen'
  condition:
    - condition: template
      value_template: '{{ states.sensor.apple_last_seen.attributes.hidden != True }}'
  action:
    service: notify.pushbullet
    data_template:
      title: 'apple is on'
      message: 'apple - on'

Then I’ll have another automation which checks to see if states.sensor.apple_last_seen.attributes.hidden is true and the datetime in the state is a couple of minutes old.

Can anyone give me an example of how to change state attributes for a MQTT sensor? Thanks!

Actually I decided to use two different groups and toggle the visibility on those instead.
