The DSP-W118 is a WLAN-compatible adapter plug that actually integrates stupid consumers, such as lamps, into the network and makes it controllable via app or Alexa. We test the device.
With the DSP-W118, D-Link has a new adapter plug on offer. It is part of our thematic world of WLAN sockets. There we published, among other things, the test of the TP-Link Kasa (test report) and present ideas and purposes in practice.
D-Link makes it easy for the customer. In addition to the actual plug, you need the Mydlink app (available for Android and iOS) and an account with the provider. Then the app guides you through setup. The DSP-W118 does not have Bluetooth, so you have to connect to the WLAN that the plug comes with. The necessary information for this is stuck on and is also in the QR code on the side, which you have to read in during setup. With Android, we had the problem that the smartphone automatically dials into the mobile data network instead of staying in the local WLAN of the D-Link DSP-W118. Then the transmission of the information of the house WLAN is not possible. D-Link provides exemplary information in the app. The setup is completed in about 5 minutes. Then you can name the connector, assign a suitable icon and put it in its place.
Control over the socket (and all other D-Link smart home products) is via the Mydlink app. After a little getting used to it, it is quite easy to use. The set-up adapters appear directly as links in the app and can be switched on or off with a click. In addition, one-tap functions can be used to create scenarios and link them to multiple devices. It is annoying that the app must have an online connection, even if you only want to control the devices in the LAN.
In addition to control via app, the D-Link account can be linked to the digital assistants from Google and Amazon. This is done via the respective app, only the access data are important, they must be entered in Alexa or Google Home.
WLAN-compatible adapter plugs have the highest energy requirements of all radio plugs. That doesn't really matter, because the plug is in the box anyway. But if you are planning more than one connector, you should think about whether you would prefer to use a more economical solution. The D-Link DSP-W118 draws between 0.6 and 1 W from a socket during operation. For comparison, the WLAN connector Kasa from TP-Link needs between 0.7 and 1.4 W. The DECT connector Fritz DECT 210 (test report) needs between 0.4 and 1.5 W.
The D-Link DSP-W118 cost almost 33 euros at the market launch in September 2019. In January 2020, the price dropped slightly, the devices can be obtained for less than 30 euros. For comparison, the already tested TP-Link Kasa HS110 costs about 22 euros.

In short: the adapter plug does what it should. It is quickly set up and can be easily controlled via the app. If you only want to control a few devices via smartphone or Alexa, you can access the D-Link plugs. However, if you have a lot of devices, you should rather use plugs with Zigbee or Z-Wave, which then also do not burden the WLAN.
