I know this has been an issue that some have been experiencing for a while now. Our monitor software team is trying to track it down while simultaneously moving forward with important improvements. It does seem that there a few different issues that are causing loss of connection, which complicates things a little. The best thing to do would report when this happens, if it is connected to a power loss event, and if you know how long the event was. There is a possibility that it is a hardware and if that is the case, we’ll definitely explore the best way to correct the issue.
I can definitely create a a quick manual for what to do if your Sense loses connection. As I mentioned before, we’re working to add a notification for loss of connection. We’ll likely include some guidance in that as well.
I’m sorry if this has been an issue for you and hope we can get it resolved soon!
