Hi!

I'm discovering HA. I want to have specific behavior when no one is home. How do you signal no one is home? I cannot do it via phone because we put our phone in airplane mode during night plus sometimes we have friends home I don't want to register everyone's phone.

I need a basic button to say OK everyone is out.

Today I have a IKEA Dirigera setup + Google Nest.

I have a couple of unused ESP8266 laying around...

Any suggestion?

I would just use the old "Home changes to 0" state, and add a conditional for night (not night) and another for a triggered timer. I call my timer "Nanny mode", and it just blocks 'away from home' automations while it's running. I just need to remember to hit a button on my dashboard once a day or so, starting the 16h timer.

Here's my "set the alarm and lower the blinds when we leave, and put them back when we get home" auto:

  - platform: state
    entity_id:
      - zone.home

      seconds: 0
    id: Left home

You managed to solve two problems for that I hadn't even articulated yet, thanks for sharing!
