Minimote Offline 4 Days

[JDRoberts]

Quite a few people have reported this with one device or another since the most recent platform outage/hub update which was, perhaps not coincidentally, four days ago.

Hub Firmware Release Notes - 18.18

My Aeon Minimote is showing the same “Device Health” warning. I charged it, used it multiple times over a 2 day period and it still shows as being offline (yet it works fine.) So, I disabled the Device Health feature as it seems to be more buggy than it is worth, IMHO. I use the very simple “Device Monitor” and “Battery Monitor” SmartApps which seem to work very well.

I would definitely report it to support.
