WisMesh Ethernet MQTT Gateway

What Is WisMesh Ethernet MQTT Gateway?

The WisMesh Ethernet MQTT Gateway is the solution to connect your Meshtastic devices with the cloud. It provides an interface from your Meshtastic nodes to either the Meshtastic MQTT Broker or to your own MQTT Broker. Whether you want to send sensor data, location information, or even text messages to the cloud, this device is the one you need.

This Meshtastic MQTT PoE Gateway uses our WisBlock RAK4631 Core module, which is pre-flashed with the Meshtastic firmware. Besides the LoRa connectivity, it uses our RAK13800 Ethernet module to connect to the internet and is placed on our RAK19007 Base Board.

The RAK19018 PoE module is an optional accessory that allows the gateway to be powered through the Ethernet cable.

Select your preferred configuration:

• Ethernet Only for basic connectivity.
• Ethernet + PoE for a streamlined setup with Power over Ethernet support.

Both bundles are pre-assembled and ready to deploy for immediate use. It comes assembled in our Unify Enclosure 150 mm x 100 mm x 45 mm with an external LoRa antenna and waterproof Ethernet connector.

The WisMesh Ethernet MQTT Gateway comes pre-assembled and pre-flashed with the original Meshtastic firmware-RAK4631_eth_gw, which supports JSON over MQTT.

Everything required to start is to set up our Ethernet Gateway with the Meshtastic app for mobile through BLE.

Why You Need WisMesh Ethernet Gateway
