I can see that the emontx-3phase repo was last updated 8 months ago and the default emonTx v3 firmware was updated a number of times since then. Are the two code bases pretty similar and is there important features that are missing from the 3phase version?
The README for the 3phase firmware says that it uses the same voltage value for all 3 phases and the inaccuracy isn’t too bad. Does it do anything like what the IOTAWatt does to generate a derived voltage value?
I’m guessing there’s no way to order an EmonTx preloaded with the 3 phase firmware?
