Before 6.0.6 download the firmware 5.9.3 from Misenkooo.
If this is your first time powering it on it will create an access point (AP) and you should connect to the iSpindel WiFi network. Then open a browser and go to http://192.168.4.1. If you ever need to reset the WiFi to get back to the iSpindel network AP click the reset button 3 -4 times then connect to the iSpindel AP (will need a small flat head screw driver).
Go to the Maintenance page and scroll down to the Firmware update, select the file you downloaded above and click Update.
Reconnect to the iSpindel AP
Go to the Maintenance page and click calibrate.
Brewer's Friend expects the gravity to be in Plato since the iSpindel does not send a gravity unit.
This also maybe useful http://www.ispindel.de/tools/calibration/calibration.htm.
Verify the calibration on the Info page, you should see near 0.00 Gravity.
Go to the Configuration page and enter your WiFi SSID and password.
The update interval should be not less than 900 seconds or 15 minutes, 3600 for every hour.
