HA Im Home detects when you arrive home and instantly triggers your Home Assistant automations — before you even reach the door
HA Im Home detects when you arrive home and instantly triggers your Home Assistant automations — before you even reach the door.
HOW IT WORKS
The app uses a combination of GPS geofencing and barometric pressure (elevator detection) to know you're almost home. It then connects via Bluetooth Low Energy to a Mac Mini running the HA Im Home daemon, which securely notifies your Home Assistant instance.
No cloud servers. No subscriptions. Everything stays on your local network.
