The device uses an ESP8266 microcontroller, a temperature sensor, and a 3D printed coaster. It exports temperature data in Prometheus format, allowing the author to monitor and receive alerts through Grafana and Discord about the tea's drinkability. All necessary resources and code are available on the author's GitHub. ## Full article daily.dev links to this article rather than hosting it.
