# MQTT Synchronization

MQTT sync should be used to synchronize players that don’t support [standard local network synchronization](/dise/docs/synchronize-players) over local network (TCP/UDP). MQTT synchronization can either be done over the internet or with a local MQTT broker set up on a dedicated Windows or Linux device.

## Sync over Internet

Platforms that don’t support sync over local network (TCP/UDP), will sync over internet (MQTT) by default with no MQTT server needing to be specified:

- Samsung
- BrightSign
- Sony Android
- Philips Android

## Sync with a Local MQTT Broker

To set up sync using a local MQTT broker:

- A dedicated Windows or Linux device is required.
- All devices and players must be connected to the same local network.

1. Download and install mosquitto (MQTT broker) - [https://mosquitto.org/download/](https://mosquitto.org/download/).
2. Locate the mosquitto.conf file.
  1. The default path on Windows is C:\Program Files\mosquitto\.
3. Add the following lines to the configuration file:
  1. listener 9001
  2. protocol websockets
  3. allow_anonymous true
4. Start the mosquitto service:
  1. WinKey + R → services.msc → mosquitto broker → Start/Restart
5. Allow the port through the Windows firewall by running this command in terminal:
  1. `netsh advfirewall firewall add rule name="Mosquitto WS" dir=in action=allow protocol=TCP localport=9001`

## Set up Sync in the CX Portal

1. [Configure sync in the CX portal](/dise/docs/synchronize-players).
2. Add the [custom setting](/dise/docs/custom-settings) `One.MqttServerUrl` with value `ws://<local-mqtt-server-ip>:9001/`
