My IoTaWatt auto-updated to 02_03_13 on 9/12 (updates set to MAJOR). Uploads to emonCMS ceased around five days thereafter, having worked very reliably for months preceding this event. Log here: iotamsgs.txt (9.7 KB)
The IoTaWatt seems to be functioning ok - the status in iotawatt.local shows current power correctly, and the LED is flashing green as normal. Device hardware is around one year old (ordered Oct 2017, but only installed Jan 2018). Looking through the forums though it doesn’t seem to be related to old datalogs (Problems with datalog on older units (>1 year)) as I have flashing green LED (not solid green).
One clue may be that in status on iotawatt.local under emoncms it reports:
