Quick Start (MqGateway)
Quick start guide shows how to connect a relay module and configure MqGateway to control it. Connecting other types of devices is similar and can be done with the similar steps.
Remember that electricity can be dangerous. You can try this guide without high voltage electricity, only with 5V power and relay module (EMR type). This way is much safer, and you still will be able to know it works correctly, because toggling this type of relay can be easily heard.
What do you need
- MqGateway with NanoPI NEO
- SD card (minimum 8GB)
- Relay module (EMR) with screw connectors
- Ethernet cable (with RJ45 connector on one side only) to connect relay module
Connect and configure device
Warning
Make sure MqGateway is never connected to power supply and micro USB port at the same time. This will destroy the device and may damage your computer.
-
Download UniGateway SD card image for MqGateway from here.
-
Flash SD card with UniGateway (you can use Balena Etcher).
-
Insert SD card to NanoPi NEO in MqGateway and power up MqGateway.
-
Connect MqGateway to your router with ethernet cable and power up MqGateway.

Connect the module to MqGateway port number 1 (ports).
- Open browser and go to http://unigateway.local:8080/ui. Take into account that it may take a few minutes for Unigateway to start after booting MqGateway.
- Go to "Devices".
- Change the switch for "Workshop light".
State of the relay should change. You should easily hear the characteristic click of the EMR relay. You can try toggle device state for a few more times to check that.
Congratulation! You have just configured your first device with UniGateway on MqGateway 🎉.
