Bar signal
One tap.
The bar knows.
You keep playing.
Strofa includes a bar signal — a big, unmissable button that sends a signal to the Strofa Display on the bar. The bartender sees it light up. You get your beer without leaving the stage or shouting across the room.
How it works
Professional tool. Slightly ridiculous.
Absolutely necessary.
The bar signal is tucked into the Strofa app. When you need a refill mid-set, tap the big button. A signal fires in real time to the Strofa Display — the screen you've set up facing the bar. It flashes the signal for a few seconds, then goes back to normal.
No app on the bar side. Just the display browser running in kiosk mode on a Raspberry Pi or any screen. The bar staff sees the flash, interprets it correctly, and a beer appears at the stage monitor.
It is, genuinely, a professional musician quality-of-life feature. You have your hands full. The set must continue. These problems are solvable.
- One tap in Strofa app → signal on the display screen
- Visible flash animation on Strofa Display
- No extra hardware or app needed at the bar
- Works over venue WiFi in real time
- Works independently of song requests or Now Playing
More options
Shelly smartplug.
DMX lighting.
Three ways to reach the bar.
Beyond the Strofa Display, the beer button can trigger a Shelly smartplug — connect any physical device to the network and it activates when the signal fires. A lamp, a buzzer, an LED strip. Visible from behind the bar without anyone needing to look at a screen.
With Strofa's built-in DMX controller, you can tie a lighting scene to the beer button. The preset fires when you tap, the stage lights do something unmissable for a few seconds, then return to your active programme. No extra software — it all lives in Strofa.
- Shelly: trigger any 230V device over local WiFi
- Shelly works without cloud — local network only
- DMX: use any scene from Strofa's DMX Studio
- All three together — Display + Shelly + DMX
One button. Three ways to signal.
