Now that you can easily add a Nest Protect to Home Assistant, I am looking at creating an automation if it detects smoke.
The automation will unlock 2 doors, turn on all lights and I have a few air purifurers around the house, I am not sure if I should turn these off or set them full.
What other automation have people done with their smoke alarms
How about sending yourself a notification for when you’re not at home? Would be the first thing for me.
Hi !
As smoke can come from the air purifier I would turn them off 
And what sounds basic to me when smoke is detected : Sound notification on my phone !
I’m using the Critical notifications | Home Assistant Companion Docs to make a sound notification
ah yes, I didnt think of notification because I already get one with the nest app but it doesn’t hurt to get extra notifications
Yeah if there’s a fire you don’t want to fan the flames with moving air. Leave the purifiers off.
Critical notifications are a must in case your phone is in “do not disturb” mode.
