# MQTT integration with Widgelix

Lightweight publish/subscribe messaging protocol

MQTT is the standard protocol for connecting gateways, edge controllers, industrial devices and Wi-Fi or cellular sensors. Widgelix runs an MQTT broker, so any device or gateway that speaks MQTT can send data without a custom backend.

[Setup documentation](https://docs.widgelix.com/connectivity-integrations/options)

How data reaches Widgelix

Devices publish to the Widgelix broker on a per-device topic (for example devices/{{deviceId}}/uplink), authenticated with the asset's access token. Topic templates are configurable per asset.

Downlinks

This integration delivers uplink data to Widgelix. Sending commands back to devices through it is not supported yet; contact us if you need it.

Setup

## Connect MQTT in a few steps

- 01 In Widgelix, choose MQTT as the asset connectivity, copy the access token and set the uplink topic template.

- 02 Point your device, gateway or edge controller at the Widgelix MQTT broker and publish to the topic.

- 03 Decode the payload in the asset template; JSON payloads map straight to data fields.

Why connect it to Widgelix

## What you get with MQTT data in Widgelix

### Gateways and edge

Bring Modbus, BACnet or local data in through any MQTT-capable gateway.

### Per-device security

Each asset has its own access token and topic.

### One platform for all protocols

MQTT devices share dashboards and actions with LoRaWAN and Sigfox.

## MQTT integration FAQ

#### Do I need my own MQTT broker?

No. Widgelix runs the broker. Devices connect to it directly with the asset's access token.

#### Which payload formats are supported?

Any format your decoder can read. JSON is the easiest; binary payloads are decoded with JavaScript in the asset template.
