Nifty! I built something similar for my university graduation project. Did a PCB, ESP8266 based as well. Temperature, humidity, sound, vibration, airborne particulate sensor, and some other stuff.
Wrapped a server up in docker for receiving the data, basic dashboard in JS for minor reactivity in components. Never ended up actually doing it cause I didn't have a consistent host, but maybe I should spin it up again now that I have a home server.
Cool project, looks neat! Anything you were caught off guard by when doing this?

Seems like both at a glance
