Suggestions?

Not seeing it across my growing numbers of iroombas.

When do you see it?

If all the time - turn debug on, and enable check box - there is a logging line above this that details msg received and payload. Presumably something is up with the payload.

This is the an example of debug message a few lines higher.

Code: Select all

 on_message: msg.topic:$aws/things/D16A1E25D11D4FD5ADBD2F6C4782B861/shadow/update msg.qos:0 payload:b'{"state":{"reported":{"cleanMissionStatus":{"cycle":"clean","phase":"run","expireM":0,"rechrgM":0,"error":0,"notReady":0,"condNotReady":[],"mssnM":0,"expireTm":0,"rechrgTm":0,"mssnStrtTm":1676089385,"operatingMode":2,"initiator":"localApp","nMssn":662,"missionId":"01GRZBCR18E4A969YC9T6P5ZCW"}}}}'


Edit:
Have had a look - and think can see what is happening. It would appear the plugin is receiving a bad json message which causes a ValueError, flowing on to this exception later. Quite what the message is would probably be useful.
Try 0.9.21
https://github.com/Ghawken/Indigo-iRobotRoomba

Fixes this issue, and debug log will show what the message was.

Thank you, Glenn for the quick turn around! Latest version installed and debug is on. Will share the message when it happens, which is sporadic.

Thanks for the log.

Unfortunately it looks like I’m not capturing the issue as I thought I was. (the error is coming through not as a dict which I didn’t alter). But at least with the logging now - can fix specifically for it as well.

Won’t be too long.
[Edit]
try 0.9.22:
Should catch better
& you should be able to turn off debug logging.


Your iRoomba seems to be sending regular error messages (which is why only you seeing this - the error message isn’t a json formatted message which they all should be) which is what is causing this Plugin issue. Probably pay at to force reboot it and see if revolved….
