Meeting Timer for OnlyT

Turn your Stream Deck into a dedicated remote for the free OnlyT meeting timer.

Whether you're running a mid-week or weekend meeting, this plugin puts the timer under a physical key with live visual feedback.

Features

One-tap start / stop — press the key to start the current timer, press again to stop it.

Live countdown on the key — remaining time and the current talk name update every fraction of a second.

Automatic colour-coding — the timer fades from green → amber → red as it approaches, and then passes, the target time.

Two-way sync — changes you make inside OnlyT (jumping to a different item, starting and stopping the timer, are reflected on the Stream Deck almost instantly.

Offline detection — a clear indicator when OnlyT isn't reachable, so you always know what state you're in.

Setup

Install the free OnlyT application on the same PC as your Stream Deck.

In OnlyT, open Settings → API and enable the REST API (default port 8096). If you are using other ports, simply change this either within OnlyT or in the Stream Deck Meeting Timer settings.

Drag the Meeting Timer action onto a Stream Deck key.

If OnlyT and Stream Deck are on the same machine, you're done. Otherwise, open the key's settings and enter the host, port, and optional API code.

Requirements

Windows 10 or later

Stream Deck app 6.9 or later

OnlyT 2.5 or later with the REST API enabled
