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.

Building an occupancy sensor with a $5 ESP32 and a serverless DB
Bluetooth is fun.
A while ago I was playing around with libble++[0] to read the data from some cheap temp/humidity sensors which broadcast their data as an advertising packet. Pretty simple, considering.
Did some other playing to turn my laptop into a BLE beacon (which worked pretty well with some random app on my phone) and also tried (IIRC successfully) to emulate one of those apple airtags though that code is lost somewhere on said laptop.
A quick glance at my temperature reading code and I'd say that counting the number of seen advertisements would be trivial using that library, I'm currently letting it do all the real work and just filtering the results to the devices I'm interested in.
