Big Head is a deployment of various home dashboard / monitoring tools, because it might be fun and cool.
All services are running via docker / docker-compose, across a variety of devices.
Big Brain is the brains of the operation. Heh heh heh. Every piece of data will feed into the brain, and it'll also host all the crap for visualising it and what not.
Big Nose is a minimal deployment of BalenaSense/sensor, intended to be hosted on a Raspberry Pi, running balenaOS, with a BME680 environment sensor doodad. It will take continual measurements, which it will feed into Big Head via MQTT.
