Exception after edit uploader, now Heap memory has degraded reset loop

Support
1

Hello,
Looking for help on how to solve this issue:

I changed the influxdb2 uploader:

  • it was running fine uploading 10 inputs,
  • added 10 integrations (all inputs to Wh),
  • added the 10 integrations as measurements to uploader (total 20) (possible problem: one of the new measurements had the same name as a previous one, it appeared to overwrite the previous one).
  • looks like new measurements were uploaded twice (two timestamps, but all Wh values are 0)
  • then iotawatt became unresponsive.

I had to pull the SD card to get at the logs. Looks like an exception occurred after adding the new measurements:

SD initialized.

EDIT:
The iotawatt had been running for about 22hr since initial setup. The resets don’t fix the heap issue. LED status: green then a really jittery dim red that can’t be counted.

Take a look at the integrator documentation. They are only needed for tracking bidirectional energy flow, like energy import and export from/to the grid when there is PV generation.

There is significant overhead in maintaining each integrator. You should remove those unneeded integrators and simply upload the kW for those measurements.

3

I need to edit the config manually: for a valid config, do I remove the “integrators” key, or leave it there with an empty array?

Also, I’d like to reset/delete all existing data/history: while I have the sdcard out, is there a file I can delete to do this safely?

Thanks!

Either way.
