Pytilt

Tools for reading your Tilt brewing hydrometer on a Raspberry Pi and storing the results as CSV.

Dependencies

• sudo apt-get install python-bluez
• Make the bluetooth interface accessible without being root:
  • sudo setcap cap_net_raw+eip /usr/bin/python3.7 (for example)
  • Note: this command does not follow symlinks so applying it to /usr/bin/python3 won't work
  • You need to run this command whenever apt updates that library

Running

From the directory containing pytilt.py run python pytilt.py
