What else do I need?

In addition to the gateway itself, a WLAN network and, if necessary, a device for setup. Your smartphone is enough for us.

When using your GatewayPLUS SMART in a company network, you should also make sure that port 1682 and the host name minihub-input.aktiver-emt.de are or will be released. If these are blocked, the gateway cannot establish a connection.


The construction is very simple. Remove the plastic cover on the back of the gateway and slide the socket adapter in until it clicks. Complete!


Plug the just assembled gateway into a socket near you and in the reception area of your WLAN network. The device starts automatically and indicates this with an orange LED on the top.

From here there are two ways to proceed. In In either case, the connected gateway remembers its credentials and can be easily unplugged and plugged back in. When plugged in again, the gateway automatically reconnects.

Variant 1 – Setup via Smartphone:

The gateway works in Wi-Fi station mode until it is already connected. This means that you can dial into a WLAN network of the gateway with your smartphone. The network name (SSID) of the gateway is on the back of the sticker and follows the scheme “IoTGatewaySmart-XXXXXX”. You will find the password right next to it.

After dialing into the gateway’s WLAN, the setup page opens automatically, if not, it can be accessed via in the browser itself. Firefox or Chrome is best use.

Select the desired WLAN for the connection and enter the password as usual. If necessary, you can also enter the SSID yourself here. The window closes itself as soon as the connection is established and the gateway shows the correct connection via a green LED.

Setup via Laptop or PC

If you do the setup on your laptop, the process is very similar, but you have to connect to the web interface manually after you have connected to the gateway’s WiFi network.

To do this, enter the IP in the address line of your browser and end up in the same mask as with the smartphone.

Here you select the WLAN at your home just like above and enter the password so that the gateway can connect.

Here there is a small difference compared to the smartphone.
On your PC or laptop, the browser window does not close automatically as soon as your gateway has established the connection, only the status of the web service in the top right corner changes from connected to disconnected and the color changes from green to red .

Don’t be confused by the fact that the animation keeps moving and Please Wait is displayed, just check the LED on your Smart Gateway. If this lights up green, everything is fine and you can close the page.

Variant 2 – Using the WPS Button:

Config button on top

If your router has a WPS button, all you have to do is press and hold the config button, which you can find on the top next to the LED, for 5 seconds until it starts flashing. Then you have 2 minutes to press the WPS button on your router. The gateway and your router will then connect automatically. If everything went well, you can see this from the green LED.

Attention, this variant can get stuck with some WLAN routers when the connection is established, despite following the instructions carefully. If this is the case for you, reset the gateway and use the direct connection via smartphone.

Reset to Default

If the gateway should forget its previous login information, you can delete the cache using the reset button on the bottom. Hold down for 10 seconds until the LED lights up orange again. Then you can start again at the point setup.
