IotaWatt Hub Hung?

1

I have had Iotawatt running without issue since May this year. Yesterday afternoon I checked the Status using the web interface and noticed it stopped reporting. Refreshing my webpage indicated the IotaWatt was not responding. I was unable to ping the hub.

Checked my wifi but all appeared good. I rebooted the router but that didnt help
In the end I unplugged the iotawatt hub and plugged it back in. Voila… all was/is good.

Given that this hub ran flawless for 7 months and had seen no changes (at least not by me) in months, what could cause this hub to suddenly hang? Is there anything I can look at to help me find the cause?

It’s not clear from your post if you simply couldn’t communicate with it or if it stopped working (sampling and recording). Check the status of the led if it happens again.

Check to see if you can Graph+ any data from that period. Lastly, please post the message log and when this outage occurred.

That was quick. Pretyy sure it was nothing more than a communications problem.
After I posted the above I checked the data during the “down” period it appears to be all there… The issue occurred sometime between 4:30 - 5:00 PM on Nov 17/22. The message log is below:

Nothing apparent. Note the led if it happens again.
