I have no problems with 2 iPhones in the household. But I also always tell my wife not to close the Homey app completely. I do not know if she follows this and if this could possibly be a problem.
You can use Apples Shortcut app and start favorite flows of Homey (person x coming home / person x leaving home), or use WebHooks to start flows. Because the whole thing is handled within the “Apple Universe” and no additional red party apps are needed on the iPhones, it is a very reliable method, as long as Homey has an active internet connection. But Homey has to have that for all other methods as well, except for the WLAN apps.
Here you can find a tutorial about the Shortcut app. But they use a HTTP-Request instead of a WebHook.
I guess that the variant with the WebHooks has already been explained in the forum as well. If you don’t find anything and are interested in it, then let me know.
I don’t use the app myself, but I have read that the Connect Life360 app is also very reliable.
With both methods you can also track multiple locations.
