It indicates that it is taking too long to get the response back from SmartThings. Could be a network issue, or you just may have too many devices. If you want me to look at the logs, I need the debug logs. Follow the link for instructions. Send the logs directly to me at iklein99@comcast.net.

Thank you! I just sent the logs.

This issue seems to be that it is taking too long for you to get a response from SmartThings. I've seen two responses for two devices take 4 seconds to return responses from SmartThings. On top of that, every single device you have, the plugin requests updates, and you're also polling each devices every 5 seconds, making it worse. You have to look at why you are getting slow response from ST. I can't help you with that. The other thing you can try is using the webhook capability which eliminates the polling. You would get updates automatically when they occur. Not sure if this will fix your issue or not, but the service is free for the first 7 days.

One other thought here. There are 5 polling configuration settings. You can start by changing them all to zero which will result in no polling, and see you can at least get rid of the errors. Then you can add them back in, but make the numbers larger. They are the number of seconds between polling those types of devices. So, maybe make them all 30 or 40 to reduce the number of polling events. Let me know how that goes.
