The new Pi 3 has both bluetooth and wifi on it. I'm thinking it might make a good data collection/wifi repeater device for use with the brewometer.
I've got some python and php code that runs on a Raspberry Pi 3 / Raspberry Pi 2 (with a bluetooth LE dongle) LAMP server. It interrogates the Tilt/Brewometer once a minute and logs the result to a MySQL database. Some additional php code displays the information in a graphical form on a webpage. It does require some knowledge of linux (I use debian, but raspbian lite also works. Here's a screenshot of the graph.
It should be noted that the temperature displayed is off by about 4 degrees, based on the reading from my ESP8266-based Temperature controller, which has a temperature probe placed directly into the wort via a thermowell.
The SG reading is also off by about 4 points, based on readings taken with my eDrometer. This varies with each Tilt/Brewometer and the Android and iOS apps allow you to compensate your readings. A little code addition would allow the same with my code. I prefer using the Tilt/Brewometer to show the trends, rather than using the data directly.
If anyone is interested in trying out the code, PM me.
