Troubleshoot timer sync issues
Remote Timers displays compute the countdown from a shared end time with server clock correction, so most glitches self-heal: a display that loses network keeps counting locally and re-syncs the moment it reconnects. When something genuinely looks wrong, it's almost always one of three things — a stale browser tab, a hit connection limit, or a device clock the correction is masking.
Refresh the display first
A hard refresh of the display page (or closing and reopening the browser on the TV) re-establishes the connection and pulls the current state. This resolves the majority of frozen-display reports.
Check your connection limit
If a new display shows a connection-limit message, open the Connections page: you'll see every active viewer. Force-disconnect stale ones (idle connections also clean up automatically after a few minutes), or add capacity in billing.
Confirm the timer is actually running
A display showing no countdown may be correct — the timer might be reset or expired. Check the hub row for that timer and start it with a preset.
Rule out the network path
Displays need outbound HTTPS/WebSocket access. On locked-down venue Wi-Fi, make sure the network doesn't block WebSocket connections, and prefer wired or strong-signal placement for permanently mounted screens.
Common questions
Two screens show times a second apart — is sync broken?
Sub-second render differences between devices are normal (each screen repaints on its own cycle). The underlying end time is identical, corrected for each device's clock drift — both screens hit zero together.
The display kept counting during a Wi-Fi outage. Did it drift?
It counted on its last-known state, which is by design, and re-synced to the server the moment the connection returned. Any drift accumulated offline is corrected at re-sync.
My theme change isn't showing on a display.
Enable the auto-reload theme updates setting so displays apply theme changes live, or refresh the display page once.
