Is there any way to read the Sonos System for alarm events?
I want to be able to get some actions done as soon as a Sonos alarm is happening. (and no it is currently not yet possible to use home assistant to trigger the wake up alarm for various reasons 
I believe I have what you need!
This is the automation I use to turn on my lights when the Sonos alarm goes off, the luminance is below 5.0, it is between midnight and 8 AM and the light is not on.
automation 3:
alias: "Wake up Lights"
trigger:
platform: state
entity_id: media_player.play_1
to: 'playing'
condition:
condition: and
conditions:
- condition: numeric_state
entity_id: sensor.aeotec_zw100_multisensor_6_luminance_5_3
below: 5.0
- condition: template
value_template: '{{ states.media_player.play_1.attributes.media_content_id == "x-rincon-buzzer:0" }}'
- condition: time
after: '0:00:00'
before: '8:00:00'
- condition: state
entity_id: light.linear_wd500z1_wall_dimmer_switch_level_3_0
state: 'off'
action:
service: homeassistant.turn_on
entity_id: light.linear_wd500z1_wall_dimmer_switch_level_3_0
data:
brightness: 100
All you need to do is change the entities to your own!
Let me know if this doesn’t work for you, I can help you figure it out!
thank you for this tip and I believe I will start with this approach.
Unfortunately what cant be done is to execute actions before the alarm goes of. (like starting the heating in the bathroom)
But its an excellent starting point to get actions done after the alarm goes of
