• Python >= 3.6
• cherrypy >= 3.0
• jinja2
• sqlite3
• A Raspberry Pi with the board described in the schematics directory
• the name of a WUnderground PWS if you want to use a software rain sensor or automatic runtime adjustment

1. Connect the Raspberry Pi to the control board and supply 24 VAC power

2. Create the sqlite3 database using the 'archive/initDB.sh' script

3. Install the pi2o logrotate configuration file in /etc/logrotate.d/

4. Run the script via './Pi2O.py'

The automatic weather adjustments are based on those used by sprinklers_pi with an added correction for the average wind speed.
