Roomba Remote Client: Unknown disconnection error: ID=16

[snowmangh]

I am regularly getting a warning saying "Unexpectedly disconnected from Roomba xxx.xxx.xxx.xxx, code The connection was lost" which I usually ignore.

But today I got this warning asking to create a new issue. So here it is. Thanks

Getting the same error but only since a few days.

I also get the following error, thought it would be a local network problem but i can start/stop my roomba perfectly via HA:

I got this error ID yesterday when my Roomba's battery died after getting stuck

I got this error ID yesterday when my Roomba's battery died after getting stuck

Yeah i took my robot out of it's dock and back in and reset HA, didn't have the error since.

@Pastaloverzzz What do you mean by "reset HA" ? Do you mean restarting HA? I did that but I am still getting the error.

[Pastaloverzzz]

@snowmangh Yes i meant a reboot. In my case the iRobot app wouldn't connect either so i think he was trying to connect to another router than the one closest to him. Could it be that the docking station isn't in a good wifi spot? If you get this error every day you could put it closer to a router and see if you keep getting the error then..

[snowmangh]

@Pastaloverzzz Interesting. I do have a mesh network at home and wondering if that could be the reason I get the error. I do have devices that for some reasons do switch between the mesh point and the actual router which is probably enough to trigger a disconnect.

[Pastaloverzzz]

@snowmangh Well, i suspect on the day i got the error that my router closest to the docking station was down. So chances are you found the culprit 🙂

[snowmangh]

@Pastaloverzzz Looks like it. Maybe the error handling should account for a short disconnect before throwing this warning. 🙂

I'm seeing the same log, I've been on vacation, the robot got stuck and drained battery, I haven't been able to make it work with HA since then.
I've already tried a factory reset, deleted the robot from HA, never been able to finish the wizard.
The DHCP lease is static and I have a single access point, so no changes in the networking as reported by others.

I see various warning and error logs:
