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.

Ask HN: What have you built with ESPHome, ESP8266 or similar hardware
This is a simple temperature sensor that runs on four AAA batteries and POSTS measurements via wifi: https://github.com/jcalvinowens/tempsensor
This is a LED wall clock that synchronizes time over NTP: https://github.com/jcalvinowens/wallclock

I tend to roll my own with rp-picos for no good reason other than they're easy. Wattmeter for a toy solar installation - broadcasts a UDP packet every few seconds, which I then record into a staging JSON log that gets ingested into DuckDB. Little pico-w wifi temperature sensor that feeds into the raspberry pi zero that controls my boiler.

The boiler control is the fun one but it's not entirely embedded stuff. Runs a little control loop that turns down the boiler modulation based upon the difference between target and current temperature. Improves operating efficiency by a fair bit and reduces temperature swings. Makes me wish residential HVAC systems were more sophisticated - these are things any good industrial control system can do.
Made an "ok to wake" light for my son -- added a controllable LED strip to his clock with a pico-w in it that changes from orange to multicolored at 6:30am as a non-intrusive "yes, you can come bug your parents" signal.)
