If your device is connected to Internet via wifi or ethernet, 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. One or more channels must also be enabled as uplink and/or downlink for packets to be transmitted from and/or to your mesh (See [channels](/docs/settings/config/channels#downlink-enabled)). Without these settings enabled, the node will still connect to the MQTT server but only send status messages.

The MQTT module config options are: Enabled, Server Address, Username, Password, Encryption Enabled, JSON Enabled, TLS Enabled, and Root Topic. 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 public server will be used.

### Username

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

### Encryption Enabled

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

### JSON Enabled

Enable the sending / consumption of JSON packets on MQTT. These packets are not encrypted, but offer an easy way to integrate with systems that can read JSON.

### TLS Enabled

If true, we attempt to establish a secure connection using TLS.

### Root Topic

The root topic to use for MQTT messages. This is useful if you want to use a single MQTT server for multiple meshtastic networks and separate them via ACLs. Default is "msh".

:::info

All MQTT module config options are available in the python CLI. Example commands are below:

:::

|         Setting         | Acceptable Values |        Default      |
| :---------------------: | :---------------: | :-----------------: |
|      mqtt.enabled       |  `true`, `false`  |       `false`       |
|      mqtt.address       |     `string`      |`mqtt.meshtastic.org`|
|      mqtt.username      |     `string`      |       `meshdev`     |
|      mqtt.password      |     `string`      |     `large4cats`    |
| mqtt.encryption_enabled |  `true`, `false`  |        `false`      |
|    mqtt.json_enabled    |  `true`, `false`  |        `false`      |
|    mqtt.tls_enabled     |  `true`, `false`  |        `false`      |
|        mqtt.root        |     `string`      |         `msh`       |

:::tip

Because the device will reboot after each command is sent via CLI, it is recommended when setting multiple values in a config section that commands be chained together as one.

```shell title="Example:"
meshtastic --set mqtt.enabled true --set mqtt.json_enabled true
```

:::

```shell title="Enable/Disable MQTT Module"
meshtastic --set mqtt.enabled true
meshtastic --set mqtt.enabled false
```

```shell title="Enable/Disable MQTT JSON"
meshtastic --set mqtt.json_enabled true
meshtastic --set mqtt.json_enabled false
```
