I get e-mails almost daily about these devices being disconnected. They’re both about 15 ft from the receiver. It makes me wonder if I can actually rely on them. I don’t push notifications from the app on my phone, so can’t compare between the app and e-mails, or app on a tablet.
I just checked the app and it says last sync was today, last connected 2 days ago and currently disconnected. I’ve pretty much given up on these devices.
