===== Things you’ll need to customize =====
* select.saunum_profile → your actual Saunum entity (or the service that starts Profile 1).
* switch.sauna_heater → your heater on/off entity (if needed).
* number.sauna_fan_speed → your AC Infinity fan speed entity (could be number.xxx, select.xxx, or a custom service).
* sensor.sauna_co2 → the actual CO₂ sensor entity in Home Assistant.
* media_player.sauna → your Sonos Amp entity.
* spotify:playlist:YOUR_SAUNA_VIBES_PLAYLIST_ID → real Spotify playlist URI for “Sauna Vibes”.

If the fan uses a select instead of number, the service lines become:

<syntaxhighlight lang="yaml">service: select.select_option
data:
  option: "3"

</syntaxhighlight>

instead of number.set_value.
