You can use IFTTT presence (called “location”) and have it turn on a virtual presence sensor in SmartThings. This is a free third-party service, but it doesn’t do any of the tracking that life 360 does. You can just have it trigger when you enter a specific location zone, like your house. We use it for housemates. You will have to install the IFTTT app on their phone, but if you do not give them that password, they will not have access to any of your other smartthings devices. Or you can give them a password and then change it after everything is set up.
