I get this “0 error” sometimes. In this case I just clicked on “last 3 hours” after viewing the day’s data. I can get it to display properly by retrying.
This happens much more frequently after a recent change in internet providers and getting a different wifi router. Is there a connection with this change?

The message is not anything that would be returned by IoTaWatt, so I suspect it has something to do with the WiFi or network. That you can simply retry and succeed supports that. I would suggest that you turn on the JS debugger in your browser and select network requests to record details of each request. When this occurs, look at the request and response to see if there is more information available.
My first time using JS debugger. Got this the last time the problem occurred.

Looks like there was no response from the IoTaWatt. That could mean it never got the query, or it could mean that it was preoccupied for an extended time and could not handle the request. Unless you have something else issuing queries to the IoTaWatt at the same time, I’d operate under the assumption that it never got the request.
Can you post the status display with the WiFi tab expanded and also the recent message log?
There shouldn’t be anything else issuing queries, I’m not connected to any of the third party graphing sites. The switch to a different wifi router occurred on Sept 15. You can see the long disconnect in the log. Attaching some more into…

I don’t see anything going on here. How often does this happen, and is there anything in particular that makes it happen?
This occurs about 1 out of 7 queries I’d guess since the new wifi router. It’s random, I don’t know of any way to trigger it reliably. I notice in the router settings that both the 2.4 ghz and 5 ghz bands have the same SSID and I don’t see any way to separate that. Could that be a problem? The SSID has 2.4 in the name but that is only because it was easier to make the SSID the same as it was in the old router so I wouldn’t have to change SSID in all my devices.
I have no problems with both bands using the same SSID.
