Is there a display that shows what’s on tap on my PerfectDraft?

Yes. seemy.beer is a tap sign for the PerfectDraft: a small screen that stands by the machine and shows the keg you have on now, with its name, the brewery, the ABV and how much is left.

You can build a sign today. You buy a screen, flash it from your browser, and set it up in a few minutes. A finished, pre-built sign is not on sale yet, so the build is the only route for now.

How the sign knows which keg is on

The sign runs in one of three modes, and the modes differ only in how the sign learns what is in the machine. In Standalone mode the sign talks to PerfectDraft itself, using the same connection the official app uses, and changes on its own when you swap a keg. In Home Assistant mode the sign reads the sensors of a PerfectDraft Pro integration you already run. In Manual mode you pick the keg by hand from the catalogue, which is what a PerfectDraft or PerfectDraft Black needs, since neither has an app of its own.

Standalone and Home Assistant both read the machine’s own figures, so both need a PerfectDraft Pro or Pro Black. Manual fits any model. Compare the three modes.

How to get one

Building a sign takes two pages and no tools. The parts list names the exact screen to buy, and the flashing guide puts the firmware on it from a browser tab, with no software to install and nothing to solder.

Pre-built signs are being worked towards and cannot be ordered today. Nothing on this site takes an order for one, and the build above is what exists instead.

What the sign shows once it is running

The keg screen carries the beer’s name and brewery, where it is brewed, the ABV and the date you tapped it. On a Pro it also shows how much is left, the serving temperature and how fresh the keg still is, all updated without you touching anything. How you see which keg is in your PerfectDraft covers the rest of what turns up on screen.

Home Assistant mode is built on the PerfectDraft Pro integration for Home Assistant, and the Home Assistant guide has the setup for anyone already running it.
