Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ACS712 Alternatives
I’m measuring AC. I’m filtering in software, using libraries that are pretty solid but I can’t find the code right now but it was based in this library https://github.com/RobTillaart/ACS712. I tried measuring the average values in chunks of 1000, reading every X seconds, Kalman filters… At the end, I was just reading raw values from the GPIO, calculating the average of 5 and printing it in esphome, but the values were not coherent at all. I never get a 0 value. On the electronic side, I tried with a voltage divider even if it’s not required but also without it. However I can try again if you know something worth to try.
