Setup Off Measure
Congratulations with obtaining your Float! Our product will help you to get more detailed information
about your fermentation process.
Each Float is individually calibrated at laboratory conditions. Measuring in an active fermentation
might yield different results depending on the circumstances the product is used in.
The Float has three modes, which can be selected by moving the sliding switch:
There’s not much you need to do, but please follow these steps:
1. Set the Float in ‘Setup’ mode. The Float will create a WiFi access point which will be visible after
1 minute.
2. Connect to the Float. For this you will need a mobile device with WiFi. On your mobile device,
disable ‘mobile data roaming’ (your 3G/4G/LTE/5G data). Look for available WiFi access points
and connect to ‘Float AP #’, where # is the serial number of your Float, which is shown on the
white label on the Float
3. Register your Float. If your mobile device does not show a pop-up, open an internet browser on
your mobile device and browse to the following address: ‘192.168.4.1’. Instructions for registering
the Float will appear on screen. The steps that follow are depicted below. Some devices might
require extra steps for connecting to the Float, please check our FAQ for further instructions.

5. Prepare for measurements. Turn off your Float and wait for at least ve seconds. Then set the
Float to ‘Measure’ mode. Your Float will now start communicating with my.brewbrain.nl. You can
now screw the lid back onto the Float. Tighten the lid rmly by hand. You can do a leak test by
holding the cap under water and checking for bubbles.
6. Start taking measurements. Login at my.brewbrain.nl/Float and click on the Float you just regis-
tered. At the top of the page, click on 'start' to start measuring a new brew. The Float sends data
every 15 minutes, so your new brew on my.brewbrain.nl should receive data soon.
You’re now all set to start measuring your brews!
Charging the Float. The Float has a rechargeable battery Li-ion battery. You can recharge it with a mi-
cro-USB charger that can provide at least 5V 1.0 A. The Float only charges when turned off!
That’s it! If you experience any problems, check the recommended WiFi settings on the next page, or

Recommended WiFi settings
Some WiFi settings might not work well with the Float. When experiencing trouble when connecting
the Float to your WiFi, try changing your router's WiFi settings to:
Security
• Disable WPA3
• Use WPA or WPA2 Personal, NOT WPA2 Enterprise!
• Max password length: 30 characters! Longer passwords will NOT work!
Encryption
• WEP, TKIP or AES
Main router settings
• Enable DHCP
• Use 2.4 GHz band, 5 GHz band NOT supported!
• Use WiFi channels 1, 6 or 11, do NOT use 'Auto'
• Channel width 20/40 Mhz or auto
• Enable 802.11 b/g/n mode or Legacy mode. Do NOT use 'Auto' or '802.11n' mode
If you still experience any issues:
• Assign a static IP for your Float via DHCP settings. The Float's MAC address can be found by con-
necting to the Float's access point (Float in 'setup' mode) and entering the 'Maintenance menu'.
• Try using a WiFi name (SSID) with no spaces and special characters. The same goes for your pass-
word.
• Test if a basic WiFi setup does work, so no mesh routers etc. Try setting you modem as also the
wi acces point, and have the modem handle DHCP.
• Try creating a hotspot with another mobile device. If the Float is able to connect to that, you likely
still have wrong WiFi settings.
