Feature Request

  1. Most recent raspbian distro
  2. Removal of bloatware from Raspbian (games, educational as discussed)
  3. Hivetool Support Pi & Pi2 (auto detect preferred)
  4. Automatic removal of erroneous data from sensors
  5. Basic navigation from webserver index.html, especially config.pl and Hivestats with download.
  6. Menu driven selection & configuration of sensors (gpio 2,3 for DHT22s preassigned by menu default)
  7. Menu driven setup of essential parameters with choices that don't crash app when saving, grey out unused.
  8. Sensor calibration provisions (gain, offset)
  9. Display instantaneous sensor readings from config screen with read button
  10. Preload & configure Apache Webserver and database, Hivetool, sensor drivers for proven sensors.
  11. Update local & online hivestats graphs to display lux trend pen, (use latest hivestats with enhanced autoscaling for local)
  12. Network / wifi support out of the box seems to work well now, handle configuration on router side with DHCP reservation as may be needed.
  13. Add configuration menu item for naming pi, same as hivestats name?
  14. Minimize need to enter Raspiconfig, can timezone and time all be handled in hivetool config?
  15. Enable i2c & serial.

Bug Fixes

  1. Add timeout to crontab so hive.sh can't hang.

       ssid="dlink"                                                                                                                                                                
       key_mgmt=NONE                                                                                                                                                               
       auth_alg=OPEN

sudo apt-get autoremove
sudo apt-get clean
rm -rf /home/pi/python_games
sudo rm -rf /opt/vc
