Very cool! I added the logging time estimation issue as an enhancement on github. It’s a good idea, I hope to get to it soon.
I was just curious to see the data… I’m always interested where meters end up and how they are used.
We have the same issue with hot and neutral sometimes being switched with plugs in the US even though officially the issue is solved. You reminded me of a very funny story about its development here (if you’re into nerd literature): http://amasci.com/amateur/whygnd.html
