I get this message below but once I fix the bad device but there is no way of resetting the exception.
com.hubitat.app.exception.LimitExceededException: Device 2420 generates excessive hub load on line 111 (method autorefresh)
I must reboot the hub which is unacceptable. Please fix this.
What is the device type? What driver are you using? What is the Too many events threshold on the Device Info tab? What are you using to autorefresh the device, and how often?
The message should stop being generated once the activity drops for the device below the threshold.
