A Pi 2 at work runs a Grafana playlist on a spare display. A Pi 3 at home runs a Flask server that collects data from sensors around the house (ESP8266 + SHT20 for temp/humidity), and provides a web page that overlays sensor data on a diagram of the house. I've been curious about CO2 levels in the bedroom overnight, and have parts for that experiment on order.
