IoTaWatt constantly resetting - solved

Support

Hi,

I have 3 IoTaWatt running for several years now. Lately I have a problem with two of them. Both are constantly resetting after about 10s of runtime.

The Message Log looks like this:

I found this other post that looks pretty similar. It mentions that this might be duo to a corrupted log file, sadly no details are mentioned.

Any idea on what could cause these resets?

Seems to be failing during Emoncms upload. Watchdog timer is expiring and causing the restart. Could be SD card corruption. Can you try disabling the Emoncms uploader?

Wow that was quick. Thank you @nhasan! I just realized that my emoncms is currently broken (I am now primarily using influx). The reason the one Iotawatt was working, was that the service was stopped there… Problem solved :slight_smile:
