Hi May-DK,
To clarify, the setting in the scene or automation is still accurate, but notifications are going off while at home regardless?
If so, try deleting the automation and re-creating it.
"Turn off or delete an automation
To enable or disable an automation:
- Open the Home app on your iPhone, iPad, or Mac and go to the Automation tab.
- Tap or click the automation.
- Turn Enable This Automation on or off.
Tap or click Turn Off to choose an amount of time to turn off accessories in an automation. For example, if you create an automation that turns on the lights when you arrive home, you can have the lights turn off after an hour.
To delete an automation, tap or click the automation, then scroll to the bottom and tap or click Delete Automation. On your iPhone or iPad, you can also swipe left over the automation and tap Delete."
After re-creating it, if you find the same thing happens, were there any other changes such as changes to your network, new router, a VPN added, anything that may affect how your devices see your current location?
Let us know and we'll continue from there.
Cheers!
