Changelog

All public firmware releases, newest first. Updates install automatically over the air; see Firmware updates for how that works and how to check your device's version (Settings → About).

1.1.1 — August 26, 2026

A small patch release. It installs silently, with no "what's new" popup.

• Fixed a memory-handling issue where some widgets could occasionally show an "Unsupported size" error after an automatic refresh. It healed itself on the next wake, but now it shouldn't happen at all.
• Preparation for the upcoming HA Builder update: Home Assistant widgets using the new QR pairing now render with correct colors.
• The "what's new" popup now appears only after feature updates; small patches like this one install without it.

1.1.0 — August 17, 2026

The first major feature update.

Full screen widgets

• Switch between full screen widgets directly: hold the button down and rotate. Previously you had to return to the overview first.

Wi-Fi

• New setup method: the device can open a temporary hotspot, and you enter the Wi-Fi details on a page that opens in your phone's or computer's browser. No more typing passwords with the knob unless you want to.
• The device now remembers up to 4 Wi-Fi networks and connects to whichever is available. A half-typed password is kept if you back out of the keyboard.
• Better network discovery on the first scan (especially EU channels 12 and 13), smarter reconnecting after router hiccups, and error messages that correctly separate "your internet is down" from "our service is down".

Home Assistant

• Multiple HA widgets can now run on one device. Every widget in HA Builder gets a unique ID, and the firmware requests exactly the ones set up in the app.
• Groundwork for QR-code pairing of HA widgets (the app and HA Builder updates that enable it are coming).
• Full compatibility with the current HA Builder: existing HA widgets keep working with no action needed, and the firmware automatically falls back to the classic mode when it talks to an older HA Builder.

Other changes

• Battery level is accurate while charging and right after unplugging.
• Widget layout changes made in the app now apply reliably on the next button press.
• The device warns on screen before the 12-second hardware reset triggers when the button is held down long.
• Reworked first-time setup flow for new devices and factory resets.
• New "what's new" popup that appears once after a feature update.

1.0.0

The initial public release. The launch firmware included the widget overview and full screen views, cloud-rendered widgets configured from the ZerryBit app, the Home Assistant widget, Self-Host mode, automatic over-the-air updates with rollback protection, and the on-device setup flow.
