I have the same issue. Have two stick up Elite’s connected via POE.
When installed, one was connected as it should be (said online and connected via ethernet), whereas the other kept giving a very high RSSI reading even though not connected via wi-fi. This is still there but both now say offline when looking at device health - even though both say online on the dashboard.
Both cameras work fine and connect through live view - however, the one with the RSSI reading always says poor connection.
Have deleted the app and power cycled, however no change whatsoever.
Surely this shouldn’t be the case should it? This sounds firmware related in my humble related.
