Score table tennis with wireless buttons (Bluetooth clicker setup)

1. Why score with buttons

A clicker turns scoring from a chore into a reflex. The rally ends, someone presses a button, the scoreboard — and every other screen watching the event — updates instantly. Nobody unlocks a phone, nobody wipes their hand first, nobody loses track because a tap was forgotten two rallies ago.

It also fits how a table is actually laid out: the phone or tablet running the scoreboard sits safely away from flying balls, while the button lives at the referee's seat — or one button on each side of the table for the players themselves.

2. Exactly what to buy

Buy a wireless presenter remote — the handheld clicker made for slide presentations, around €10–15. The Logitech R400 class and its many clones all work the same way: they pair as a standard keyboard and their back/forward buttons send the Page Up and Page Down keys, which the scoreboard maps to a point for the left and right player. No app, no driver, nothing to install.

Avoid the cheap "Bluetooth remote shutter" buttons sold for phone cameras. They look ideal — tiny, one button — but they send Volume or Enter keys, which browsers and operating systems often swallow as media keys, so scoring is unreliable at best. Stick to presenter remotes.

• The compatibility check before buying: the listing should say it works as a keyboard (HID) and sends Page Up/Down or arrow keys.
• Presenter remotes with a USB dongle work too — the dongle is the receiver, and the remote still types as a keyboard.
• One remote is enough for a referee; buy two if you want one per side of the table.

3. Pairing and testing

Pair the clicker like any Bluetooth accessory: put it in pairing mode, open the Bluetooth settings on the phone, tablet or computer running the scoreboard, and connect. A dongle-based remote skips even that — plug the dongle in and it works.

Then run the ten-second test: tap into any text box (or open a keyboard-test page) and press the clicker's buttons. If they register as Page Up and Page Down — or as arrow keys — the remote will score. If nothing appears, or you get volume changes instead, that device will not work for scoring.

4. The key map

The scoring screen listens for these keys while a match is being played on it. They never fire while you are typing in a text field, and never in view mode — so a stray click cannot corrupt a score from the TV overview.

• Page Up — point to the LEFT player (a presenter clicker's 'previous' button).
• Page Down — point to the RIGHT player (the clicker's 'next' button).
• Left arrow or "1" — point to the left player (for a normal keyboard).
• Right arrow or "2" — point to the right player.
• Z — undo the left player's last point; X — undo the right player's.

5. One clicker or two?

The simplest reliable setup is a single clicker at the referee's seat: one person, both buttons, no confusion. That is the setup to start with.

For a two-clicker table, pair two remotes to the scoreboard device and give one to each side: the player on the left presses only the 'previous' button on their remote, the player on the right presses only the 'next' button on theirs. Each player presses only their own button — and the Z/X undo keys fix any slip. It feels great when it clicks, but agree on the rule before the first serve.

6. What players get out of it

Because every point goes through the scoreboard, the event ends with real data, not a final score scribbled on a whiteboard. Every game is saved with its set-by-set history, standings resolve themselves, and each player builds a record across the night.

The AI layer turns that record into something to work on: player analytics with coach-style practice cards built from how the matches actually went. On the Free plan every tournament includes one AI coaching insight; Club (or the €12 single-event pass) unlocks unlimited insights and the full player analytics.

7. Troubleshooting

Almost every clicker problem is on the device or the tab, not the remote. Work through these in order.

• Presses stop registering: the browser tab lost focus. Click once anywhere on the scoreboard page and try again — key input only reaches the tab in the foreground, and the automatic screen wake lock pauses while the tab is hidden too.
• The screen went dark: on modern browsers (Chrome, Edge, Android, Safari 16.4+) the scoreboard keeps the screen awake by itself while a match is playing and the tab is in the foreground. If an older device or browser still dims, disable auto-lock (Settings → Display) as a fallback.
• Buttons type the wrong thing: run the text-box test from step 3. Volume or Enter keys mean it is a camera-shutter-style button — replace it with a presenter remote.
• Nothing happens even though the tab is focused: check a match is actually being played on that screen. The keys are deliberately inactive between matches and in view mode.
