Gateways and edge
Bring Modbus, BACnet or local data in through any MQTT-capable gateway.
Integration
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.
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
- 01In Widgelix, choose MQTT as the asset connectivity, copy the access token and set the uplink topic template.
- 02Point your device, gateway or edge controller at the Widgelix MQTT broker and publish to the topic.
- 03Decode 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
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.
