IottaWatt not posting to EmonCMS again

1

Hi all
I’ve got an issue with my Iotawatt that’s stopped posting to my emoncms server that I’ve had before (IottaWatt not posting to EmonCMS).
This issue coincides with upgrading the firmware and subsequent restart on my access points so the Iotawatt temporarily lost connection to the emoncms server.
The only thing I’ve done since is to reset my Iotawatt to see if that resolves but I’m keen to get to the bottom of this issue.
The emoncms server is on the local network but has a domain address.

Many Thanks

Dave

To be clear, the IoTaWatt firmware was not updated, the router firmware was updated.

This looks to be the same as the last problem where IoTaWatt does not appear to be getting a response from Emoncms when uploading. It all started with the disconnect at 1:53:23. It doesn’t appear to be an IoTaWatt issue.

Have you tried just posting to the IP address of the Emoncms?

Hi @overeasy (Bob)
I can confirm that the access point firmware was upgraded rather than the firmware ion Iotawatt.
So I can get more of an understanding of the logs, where does it indicate that there’s no response from the Emoncms server?
I appreciate that you’ve indicated that the Emoncms server is at fault but this issue happened after the WiFi dropped out and I know if I issue a http://192.168.197.134/command?deletelog=both command, everything will start working again?
@wt29 Tony - That’s not a bad idea, it removes the DNS element.

Regards
Dave

Would you post the status page with all of the tabs expanded please?

Hi Bob
Sure, please see below…

So there you have it,

“Post failed, -11”

Which is a timeout of the post. It was sent and no response was received. The reason that I think it’s Emoncms is that IoTaWatt is able to communicate out to the internet to verify the auto-update is current, and it is able to request the time of last update of Emoncms.

While nuking your datalog may resolve this, my sense is worked for you in the past because it is trying to upload from where it left off and when you delete the datalog the IoTaWatt restarts and begins uploading from the present time.

Update:

Looking more closely at the DataLogs status, I am curious to know if this IoTaWatt was unused for a long period of time. The reason I ask is that the current log is normally has a year of data and the “wraps” where it starts over at the beginning overwriting older entries with newer entries. You datalog appears to span 30 months, and the size indicates it only has about 194 days of data. That is certainly possibl;e if the unit was not working for a very long time, but it could also be indicative of a datalog issue that I am not aware of. Can you elaborate on the history of this unit?

Hi Bob
Yes, I’ve had the unit for quite some time, I have four in total so yes that is a possibility.
Is that something I can download from the unit to PM you?

I think I found a solution for the “Post failed, -11” error. Enable redis in the emoncms settings.ini.

I was able to reproduce the error by disabling the redis option.

; Redis
[redis]
enabled = true

Don’t know much about how that works, but as I recall you need to be careful with redis. I think you need to setup persistence to insure that it recovers seamlessly from any outage.
