How to use next alarm sensor

Mobile Apps Home Assistant Companion for Android

I was able to get it to work by using this template.

{{now().strftime("%a %h %d %H:%M %Z %Y") == (((state_attr('sensor.joes_galaxy_s10_next_alarm', 'Time in Milliseconds') | int / 1000) + 0*60 ) | timestamp_custom('%a %h %d %H:%M %Z %Y'))}}

and this for a binary sensor. Hopefully this will help someone else in the future

- platform: template
  sensors:
    joes_next_alarm:
      entity_id:
        - sensor.joes_galaxy_s10_next_alarm
        - sensor.time
      friendly_name: "Joes Next Alarm"
      value_template: >-
        {{now().strftime("%a %h %d %H:%M %Z %Y") == (((state_attr('sensor.joes_galaxy_s10_next_alarm', 'Time in Milliseconds') | int / 1000) + 0*60 ) | timestamp_custom('%a %h %d %H:%M %Z %Y'))}}
