With so many devices it’s hard to keep track if something goes offline, or batteries start to go really low. What would be the best way to monitor this and possibly get notifications to my phone, preferably just to my phone and not the wife’s phone.
You can do this with routines, but it’s a bit tedious unless you have relatively few devices to monitor.
On Android, you can use Tasker and the projects described in this post to automate the process.
