Update 2026-07-14: The features explained in this blog have been released in the v1.1 firmware update, see also the blog post about the update.
Wi-Fi hydrometer missing readings, gaps in your fermentation graph where data should be, is something we hear from brewers regularly, and we’ve had it on our list to fix properly.
Today we’re announcing two new features currently in beta: offline data buffering and multi-language setup. Both will ship in the same firmware update, which we’re aiming to release by end of May.
Offline data buffering — no more Wi-Fi hydrometer missing readings
Brewery environments are hard on wireless connectivity. Stainless steel tanks, thick walls, cooling equipment, and crowded Wi-Fi channels can all interrupt your connection; sometimes for minutes, sometimes hours. When that happens with any Wi-Fi hydrometer, you simply lose readings. You’re left with missing data in your fermentation curve.
Buffering data was the most requested feature in our community feature development poll. So we made it a priority and built a solution for unstable Wi-Fi connectivity.
What the new buffering feature does
When your Float Pro loses its Wi-Fi connection, it stores measurements locally on the device. The moment the connection is restored, all buffered readings are automatically uploaded to your myBrewbrain dashboard. No gaps, no manual intervention.
Details worth knowing
The buffer holds approximately 169 days of measurements at a 15-minute interval. This is far more than any single fermentation requires. But we know brewers love to experiment with crazy recipes⚗️🤯. We are currently testing battery life while operating in offline mode and will share results at launch.
To maximize the number of readings that fit in the buffer, we store values in a slightly rounded format. We save the following data: Specific Gravity (SG), temperature, and battery voltage. In practice the rounding makes no meaningful difference to your fermentation curve.
We currently don’t forward buffered measurements to third-party integrations such as Brewfather. For this release we focused on getting the core buffering right, something that helps every Float Pro user immediately. Integration support is on our roadmap.
If the Float Pro powers off completely, for example due to an empty battery or while charging, it will not be able to track the time. This means measurements collected before the shutdown may show a newer timestamp than they actually have once synchronized. We are evaluating how often this occurs in real-world usage, which is one of the reasons we are running a beta.
Float Pro setup interface in your language
Setting up a device in a language that isn’t your own can be a small adventure. But you’re here to brew, not train your language skills. The Float Pro setup process will now support multiple languages. When you start the Float Pro registration, you choose your language and the rest follows naturally. myBrewbrain website translations will follow in a future update.
The available languages at launch will be confirmed in the release post.
Thanks to all the beta testers!
We’re grateful to the brewers who helped us test the feature in the field. Your real-world feedback has helped us refine the experience and ensure the system performs reliably under different brewing conditions.
Don’t have a Float Pro yet? You can order one and still join testing or start using the new features once they arrive.
