Im using Smart presence app which is using wifi connection and phone IP address to setup the presence. Works like a charm already for more then month. You just need to assign fixed IP in your router for phones that should be monitored. And no need of Homey app on other phones.
How did you set this up? I couldn’t find an updated guide, but made a location profile with entry and exit tasks. It just seems that the exit task will fire every so often while I’m not at home - it should fire only once. Was thinking about disabling the task when it ran and enable the entry task, and vice versa when the entry task is run.
