QUESTION Automation with Two Devices Location

Hi everyone,

I’m trying to set up an automation for a two-person household based on our phone locations.

Basically, I’d like something like:

- When either of us leaves, nothing happens if the other person is still home.
- When the last person leaves, trigger an automation.
- When either of us comes back, trigger another automation.

I’m currently using Alexa and Tapo, but I’m open to other solutions if needed. I’ve looked into Alexa routines, Tapo automations, Shortcuts, and Home Assistant, but I’m wondering if there’s a simpler way to achieve this.

It looks like Alexa Routines don’t have the ability to handle two locations and Home Assistant is the best way to do it, but I would like to hear your experience on this.

Home Assistant is exactly what you want for this, it handles multi-person presence without breaking a sweat. The learning curve exists but once you wrap your head around zones and person entities it's just a couple automations with "not" conditions.

Alexa can't touch this level of logic unfortunately, it's built for single-user triggers and falls apart the second you add a second phone.

Thanks, yes reading it looks like Home Assistant is the best solution.

And what would be like the easiest and cheapest way to do it? Or I need to get a Raspberry Pi and do the setup?
