It is curious. I unchecked the “show offline” command and more grey offline and online sites appeared. One in Japan shows September chart, states is online, but is a grey diamond on the map. Others that are grey, show as offline for status. For some reason, mine was interrupted and showed offline and came back online when I unplugged then plugged back in the unit’s electrical cable. That isn’t accessible to the cats (who are inside at night) so the cause of the interruption is unknown.
Each of the screenshots below are of units that show as grey diamonds on the map.
I wonder if all sites have residents in attendance keeping track of their units… maybe an email reaching out to all monitor owners (group email) to find out if everyone is still actively tending to their units would help. ~ Pia
