Is a DIY free-floating digital hydrometer and thermometer for continuous fermentation real-time monitoring that operates on WiFi. http://www.ispindel.de​
Brew Session Setup
See the Fermentation tab in a brew session to turn on iSpindel logging.  After the device logs for the first time you will see the name show up in the devices section under the Fermentation tab of the brew session.
Configuration (Firmware 7.1.2)
Your iSpindel Cloud URL can be found under integrations.  You will need this to enter into the iSpindel app.  https://www.brewersfriend.com/homebrew/profile/integrations​
Service Type: HTTP
Token / API Key: [API KEY] 
Server Address: log.brewersfriend.com
Server URL (Plato, iSpindel Default): /ispindel/[API KEY] 
Server URL (Specific Gravity**): /ispindel_sg/[API KEY] 
If this is your first time powering it on it will create an access point (AP) and you should connect to the iSpindel_iSpindel000 WiFi network.  Then open a browser and go to http://192.168.4.1.   If you ever need to reset the WiFi, calibrate or change settings 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.
** You will need to change the polynominal in the config for the correct gravity value when using the specific gravity URL.
