hörbert Firmware

“Firmware” is the name given to the software that runs on your hörbert and controls its functions.
Through firmware updates, we fix bugs, and on top of that your hörbert receives new functions free of charge.
With Butterfly2, your hörbert offers extensive podcast features that give you access to an unlimited amount of content at no cost.
You can find out everything about the podcast feature here: hörbert’s podcast feature

If you are already using the Butterfly firmware, you can conveniently update your hörbert to Butterfly2 at the push of a button in Browser Set Mode. How to update an older firmware version to Butterfly2 is explained here: INSTRUCTIONS: MANUAL FIRMWARE UPDATE

Note: Only models from October 2021 onward (all hörbert models without a toggle switch next to the volume control) can be updated.
 For older devices, we offer an upgrade to the new electronics in our workshop or an DIY upgrade kit for hörbert 2011.

BETA-Version of 21.10.2025

For those who like to experiment!
The BETA version of the hörbert firmware is not as stable as a full release, but it offers the latest features.

BETA Firmware

There is currently no public beta version available.

After installing a beta version, we recommend resetting the device to the factory settings. The same applies after installing the next release version following the beta version.

Firmware Beta Versions


hörbert’s firmware is constantly evolving. As soon as an official new firmware is released, the next small change is already included in a new Beta Version. Beta Version means something like “may not work completely, but has new features”. In beta versions, we can “just quickly” try out new features, or features that have not been tested for long enough yet.

Those who install a beta version should only do so at the behest of our customer service, if it contains a special solution for a special problem. Those who are curious – or fearless – can also voluntarily use our beta version. Then we would appreciate feedback on whether everything is okay, or if someone may have even found a possible error.

The advantages of butterfly firmware

  • All settings for hörbert can be made completely without a PC, SD card reader, or hörbert software.
  • For this, hörbert offers a web interface, the Browser Set Mode, accessible via a web browser on a smartphone, tablet, or computer. You only need a Wi-Fi-enabled device to connect to hörbert’s own WLAN and then access the Browser Set Mode through an internet browser. Further down on this page, you’ll find a brief guide on how to start the Browser Set Mode.
  • MP3 files, podcasts, or internet radio stations can be saved to the card via the Browser Set Mode.
  • Since Butterfly, files can also be copied directly to the memory card via a computer with an SD card reader.

How to start the Browser Set Mode

Here’s how to connect your computer, tablet, or phone to the hörbert Wi-Fi and start the Browser Set Mode:

  1. Turn on hörbert.
  2. Press the SET button inside; an ascending tone sequence will sound, and the green LED next to the SET button inside will light up continuously.
  3. Connect to the Wi-Fi network “hoerbert-xx:xx:xx:xx:xx:xx” (instead of xx:xx:xx:xx:xx:xx, each hörbert has a unique combination of letters and numbers).
    The Wi-Fi password is: hoerbert
  4. Open a web browser, e.g., Chrome, Safari, or Firefox, and go to the website http://hoerbert.local.
    -> You are now in Browser Set Mode.
