You basically need a Bluetooth equipped Raspberry Pi. (3 or zero W)
You copy their software to a micro SD, then run a script on the card to enter your WiFi info, and gmail email.
Put the card in the Pi, and plug it in.
Their stuff sends you an email with additional details. They have a spreadsheet template that does all the graphing. When you name your beer you get a fresh copy of the template. The Tilt Pi software just adds a new row to the sheet every 15 minutes. You can also access the Pi over WiFi, not just Bluetooth.
Form there it’s just looking at google sheets.
