You can send the data to Emoncms or influxDB. The timestamped data that is uploaded should synchronize properly to within one second.

Will the derived-reference method work if I see different voltages on phases?
example: 233.8, 237.6, 240.0
It will work, but just quite as accurate as direct reference. Note that your voltages are all within 2%. Understand that one of the phases will always be direct, so same same. The other two derived will vary by some percentage.
The overwhelming majority of IoTaWatt users with three-phase use derived reference. There seems to be general satisfaction with the result.
Same here! Do you still have the files? Once i order original device i’ll do one more from scratch. It would be very nice to see your approach. Thanks! bogus105@wp.pl
This is a very old thread. The current V5 IoTaWatt has supported three VTs for several years now. There is no need to use any type of external adapter for direct reference.
