[NOTE] The shutdown command is located on the USB autorun script, this way if you want to use the Raspberry, you can simply remove the USB drive, you will have 5 minutes to login and disable schedule script with: sudo /home/pi/wittyPi/wittyPi.sh

INSTALL

First, install WittyPi2, see: http://www.uugear.com/product/wittypi2

cd; wget http://www.uugear.com/repo/WittyPi2/installWittyPi.sh
sudo sh installWittyPi.sh

Then install wiibee (plug an empty USB stick in your Raspberry)

cd; wget http://pierriko.com/wiibee/install.sh
sudo sh install.sh

Edit /mnt/bee1/wiibee/autorun.sh, add the Bluetooth address of each Wii Fit balance board and the GPIO PIN number of each relay.

You can get the Bluetooth MAC address using hcitool scan or python /mnt/bee1/wiibee/wiiboard.py after pressing the red sync button.

Electric wiring coming soon.

For GitHub integration, fork the wiibee repo, add a ssh key, edit the remote in /mnt/bee1/wiibee, and setup GitHub pages:

TODO

Studdy the Wii Fit Balance Board electric wiring, find how can we read mass directly from the strain gauges.

STATS

A data row contains: time cpu_temp temp mass*, example: 1474272540.431 39.50 10.00 20.00 21.00 22.00 23.00, a row contains 51 bytes for 4 beehives (75 for 8).

If we do 5 measurements per boot and boot every hour, this means:

51 * 5 * 24 = 6120 # bytes per day
6120 * 30 / 1024 = 179 # KB per month

A Wii Fit balance power consumtion is around 160mW.
