If your device is connected to WiFi you can enable it to forward packets along to an MQTT server. This allows users on the local mesh to communicate with users on the internet.

The canned message module config options are: Enabled, Server Address, Username, Password and Encryption Enabled. MQTT Module config uses an admin message sending a `ConfigModule.MQTT` protobuf.

## Settings

 ## MQTT Module Config Values

### Enabled

Enables the MQTT module.

### Server Address

The server to use for MQTT. If not set, the default server public will be used.

### Username

MQTT Server username to use (most useful for a custom MQTT server). If using a custom server, this will be honoured even if empty. If using the default public server, this will only be honoured if set, otherwise the device will use the default username.

### Password

MQTT password to use (most useful for a custom MQTT server). If using a custom server, this will be honoured even if empty. If using the default server, this will only be honoured if set, otherwise the device will use the default password

### Encryption Enabled

Whether to send encrypted or decrypted packets to MQTT. This parameter is only honoured if you also set server (the default official mqtt.meshtastic.org server can handle encrypted packets) Decrypted packets may be useful for external systems that want to consume meshtastic packets.
