I have exactly the issue iOS app version 1.3.4.
Everytime after a few minutes the app shows disconnected even though both of my LR3 are online.
I tried the same trouble shooting you mentioned before several times unfortunately without any improvements.
This is usually caused by issues or maintenance on servers on Litter Robot side. Once the issue is resolved on their side, it should get disconnected so often.
From my experience, for me there are two situations.
-The majority of times the fact that the Litter Robot says that is offline is because of there servers, it’s not the litter fault or anything else, the only thing you can do is wait that the servers come online again and you will be able to access the litter robot via app again. Maybe a small server with poor maintenance, who knows.
-The other issue was the router channel on 2.4ghz, if it was on a random channel I notice that the litter robot sometimes went to offline, I suppose that this NIC, network interface cards (wireless are cheap) and therefore have bugs. Note that i don’t have interference and no neighbors, the best channel is 1 on 2.4ghz, the problem disappeared.
Don’t believe it is the server. We have 2 robots and the one that is 3 feet from our router goes offline all the time. The one in the basement far from a router never does.
Your update failed. Failed means the robot did not accept the update due to some situation out of our control. corrupted data, incomplete download, etc…
