Another option and only if you use a Samsung device with Bixby
Set up life360 to give notifications on the individuals arrival and departure
IF
Create a Bixby routine using notifications, choose life360 as the app and the notification keywords
THEN
Select Smartthings at the bottom of the routine setup and select what needs to happen in Smartthings
You may need to adjust some automations here and there to suit but its probably more reliable than the old groovy integration
