First Time Using A Gateway

Keywords: gateway, sensor, iMonnit


Brief guide on using a newly installed gateway for the first time.

Description: Once the gateway has been registered to your iMonnit® account, it will begin receiving data from sensors. An active iMonnit® account is required for your gateway to function properly. If you don't already have an account, please read the article on Creating a New Account. If you have a new gateway you'd like to register, head to the article for Registering a New Device. If you are having problems setting up a MonnitLink™ Ethernet Gateway, please see the article on Troubleshooting a MonnitLink Ethernet Gateway. 

What is a Gateway?

gateway is a device that manages communication between your sensors and servers. On startup, the gateway will periodically transmit a heartbeat, checking in with the servers to make sure it is still receiving an active signal. Sensors also have heartbeats and will relay information to the gateway, which then forwards the data to the server. There are four different types of gateways:
  • Cellular: Uses cell towers to facilitate communication between gateways and monitoring systems.

  • Ethernet: Uses IEEE 802.3 network connection to connect to the Monnit Servers. 

  • USB: Uses an existing internet connection on a PC to facilitate communication with the Monnit servers. 

  • Serial Modbus Gateway: Acts as a data concentrator for Monnit wireless sensor networks. 

Turning on the Gateway

  • Attach the Sensor network antenna.

  • Cell gateway

    • Attach Cellular Antenna

    • Ethernet gateway


The easiest way to configure settings on your gateway is logging into iMonnit through your desktop or the mobile app. The mobile app is free to use and available for purchase in the app store for IOS and Android devices.

Visit the Gateways page to ensure your gateway is active.

  • Open iMonnit.

  • Find Gateways on the main navigation page.

  • A list of all the gateways registered to your account will display. There should be at least one gateway registered to your account for your sensors to be active.

NOTE: If you have yet to register a gateway this page will be blank. See Getting Started – Registering Devices for tips on how to add a gateway to your account.

  • Select one of your gateways from the list. Active gateways are designated with a green icon.  The icon will be gray if the gateway is not yet activated.

  • There will be a series of tabs allowing you to view the status of your gateway and make changes.

A. History – This will be the first page to display.  With a list of data received from previous heartbeats. If there have been any alert states in the past, they will show up here.

B. Events – This will display a list of all the events you have under this gateway. If you have not assigned any events to this gateway, the page will be blank. For tips on how to set an event, see Getting Started – Events for more information.

C. Edit – If you would like to make changes to your gateway network connection, you can do so here under the Settings section.

D. Sensor List – Here you will see a list of sensors registered to the gateway. If there aren’t sensors registered to the gateway, the list will be blank.

For more on gateways and how to adjust settings in the edit tab visit Getting Started – Gateways.

Local Interface

Alternatively, if using iMonnit is not an option, you can adjust settings in the local interface. Step by step instructions on how to access the interface is available in the article titled: Gateway Local Interface Setup.

After Registration

It is important to note that sensors will go into sleep mode if they are powered on before the gateway is connected with the internet server.  If your sensors have batteries in them before the gateway has three green lights.  Remove the batteries from the sensors before continuing to configure your system.


You should now have all the information you need to understand your new MonnitLink gateway.
