This drives the stock firmware.

The stock app can pick colours — that's about it. Vantic firmware adds 47 flow effects, colours that survive power cycles, its own dashboard and one-click updates. One USB flash, about five minutes, and it's reversible.

Lighting

Streamlined lighting control while you stay on stock firmware — colours, presets and patterns without stock's complicated routes. It's not perfect: stock still forgets everything on a power cycle, and there are no animations. Running Vantic firmware? The dashboard at zimacube.local or 172.16.1.1 is better — it needs none of this.

Checking…
Heads up: this tool talks to your ZimaCube from this HTTPS page. Chrome 133+ will ask for a Local Network permission on first click — allow it, or colours silently fail. Clicked the wrong thing? The fixes it in 20 seconds. Firefox has no prompt — just load this page before you switch WiFi.
Chrome permissions — the 20-second primer

This page is HTTPS and your ZimaCube is a local device — Chrome 133+ treats that jump as a Local Network permission. There are exactly two things to know:

  1. The first click: the first time you send a colour or press Check connection, Chrome pops a “allow this site to access your local network?” style prompt. Click Allow. That's the whole job.
  2. If you clicked Deny (or colours silently fail while the pill up top says Not connected): click the tune / lock icon at the left of the address bar → Site settings → set Local network to Allow → reload this page. Chrome also drops a small “blocked” icon into the address bar right after a denial — clicking that and pressing Allow works too.

Still stuck after allowing? Close every tab of this site, reopen, and click Check connection — the pill should flip to Connected.

The web tool streamlines stock firmware, but stock keeps the LEDs at whatever was last sent — reload the page and resend after a power cycle. Vantic firmware gives you perfect control, persistent memory and animations: flash it in one click.
