I’m in the UK and have just got iotawatt, 9v ac ref [Ideal 77DB-06-09(UK)], and 3 CT SCT013-000
Device powered up ok, wifi and browser connection all work fine, setup appeared ok … but …
Inputs all reading as 0v and 0w
I have tested the AC ref (digi multimeter, ac voltage measurement) and it appears to be outputting as 0V +/- 0.1V, and checked multimeter against another LV AC adapter to verify not a multimeter issue
I have an old energymonitor with CTs so I also know the circuits i am measuring are drawing current
The status page is showing sampling is happening (see pic)
Does the iotawatt require the ac ref to be functioning to measure and display the CT measurements?
If so, implies my AC ref is a dud? openenergymonitor are replacing it just in case
If this is the case, might be worth updating the FAQ/troubleshooting to reflect this or adding a log entry when 0V ref is detected
If not, any ideas what I might be doing wrong or what might be wrong?
