==== 2. Triggering this with “Hey Google, start sauna” ====

Once the script is in HA and reloaded:
# In Home Assistant, go to Settings → Automations & Scenes → Scripts and confirm you see “Start Sauna (4-hour session)” (script.sauna_4_hour_session).
# Make sure it’s exposed to Google: - If you’re using Nabu Casa / Home Assistant Cloud: Settings → Voice Assistants → Google Assistant → Exposed Entities and enable the script. - If you’re using your own Google Assistant integration, expose the script the same way you do for lights/switches.
# In the Google Home app, create a Routine: - Trigger phrase: start sauna - Action: “Run script sauna_4_hour_session” (it should show up as a Home Assistant script once exposed).

After that, saying:

: “Hey Google, start sauna”

will kick off the whole 4-hour sequence: Saunum profile 1, fan logic by CO₂, music in hour 2–3, then cool-down with fan only.

If you send me your actual entity IDs (or a screenshot of the Saunum, fan, and Sonos entities), I can tweak this to be copy-paste perfect for your exact setup.
