Unit stops reading data, no web access, fine after power cycle

Hello,

Bought my unit back in 2020. Generally been running okay until this year. I’d discover an issue when it was no longer uploading data. Sometimes it was due to it falling off the wifi, due to an issue where my access point was intermittently failing.
Sometimes, I’d go to the iotawatt webpage and get the “Not found: GET, URI: /” message. I’d then power cycle the wifi and the iotawatt device and everything would come back online. For the times where the webpage wasn’t working, all input readings during that period were lost. The device would start uploading again from the restart.

I replaced the SD card about 4 months ago. I replaced my wifi access point a few weeks ago. The iotawatt is maintaining it’s wifi connection now and I’m not seeing any low heap reboots. But it’s still stopping the uploader and giving the “Not found: GET, URI: /” error message. It’s happened three times in the past two weeks. I wasn’t smart enough to check the LED error codes.

Now to my question, how do I tell if the problem is on the SD card side, or on the device side?

I’m guessing that since everything works when it comes back up it’s something starting to fail on the IotaWatt and the SD card is probably fine.

Any suggestions before I replace the Iotawatt?

I’ve uploaded my current config and the iotamsgs from the current SD card and the old one.

Thanks for your help!

Virtually all problems these days boil down to SDcard or WiFi signal quality. Your unit exhibited symptoms of both. The WiFi symptoms seem to have settled since Nov 1 when the RSSI improved considerably. Perhaps that’s when you replaced the router.

The not founf “/” looks like a problem with the SDcard. That logging stopped also suggests SDcard.

A problem with the unit hardware is very unlikely.

Thanks! I’ve ordered a Sandisk Industrial SD card like you referenced elsewhere on the forum. Hopefully, it lasts a little longer.
