Sync Settings

Who can use it: Permission: settings.view or manage settings. Not available on SureScreen plans. A restaurant on SureTill cloud does not need it: all terminals talk to the cloud directly.
Open this page in SureTill

This page has two layouts. In a web browser it manages the sync between servers (for example a server in the restaurant and a server on the internet). In the Windows desktop app it manages how the terminals of one branch connect to the main PC. Both layouts end with a Save button and both write their results to Sync Logs.

In the browser: sync between servers

Connect to a remote server

Choose a Sync Mode: Local Only (everything stays on this server), Cloud Only (sync all data to and from a remote server) or Hybrid (local first, with a copy on the remote server; the best reliability).
For Cloud Only or Hybrid enter the Server URL of the remote server, for example https://api.openpos.pro or 192.168.15.74:8000.
Both servers must trust each other. In the Sync Token box press Generate on this server and copy the token at once; it is shown only one time. Give it to the other server.
Paste the token that the other server gave you into Access Token.
Press Test Connection. The result shows Reachable, API health, Sync Ready, the latency in milliseconds and the branch names found on the remote server.
Click Save Configuration.

Run a sync by hand

Once a mode other than Local Only and a Server URL are saved, the Manual Sync card appears. Full Sync (Push & Pull) sends and receives. Push to Remote only sends this server data. Pull from Remote only fetches. The result shows how many events were Pushed and Pulled and the number of Conflicts. Errors are listed below it.

Change or revoke the token

Regenerate creates a new token and the old one stops working. Revoke deletes it; remote servers can no longer sync with this one until you generate a new token and send it to them.

Automatic sync

Switch on Auto-Sync to sync on a schedule and set the Sync Interval in seconds (10 to 3600, starts at 60). The page notes that this needs the scheduled task of the server to be set up.

In the Windows desktop app: terminals and main PC

On the PC that stays on in the branch, choose Main Server mode. Press Start in the Local Server card. The card shows the address terminals use, and Connect Tablets & Mobiles lists the addresses of the PC with a Copy button.
On every other terminal choose Terminal mode and type the address of the main PC into Main Server URL, for example http://192.168.1.100:8091.
A single device that is not in a branch network uses Standalone mode and syncs straight to the cloud.
Click Save Settings. The message Settings saved appears.
