I prefer the raspberry pi over using the phone app since the phone app only sends when you are within bluetooth range of the Tilt in your fermenter. The Tilt communicates over bluetooth to save battery so you can use a Raspberry Pi to communicate with the Tilt and send the data over WiFi to BrewersFriend. Once you have a raspberry pi, here are some steps to set this up. Download the Tilt Pi image Download Etcher to burn the image to a micro sd card Insert the micro sd card and plug in your raspberry pi with a keyboard and monitor to setup WiFi. After it's connected to your WiFi, plug it in near your fermenter and open http://tiltpi.local:1880/ui Under Logging > Cloud Settings, paste the Cloud URL from your brew session and hit enter to save it. The Tilt Pi defaults to sending data every 5 minutes and will now send the gravity and temperature of your fermentation to BrewersFriend. To test it right away, you can enter a comment and hit enter to send.
