Of course, you also need an appropriate app to be able to control this WiFi plug smartly. Meross relies on its own Meross app for this purpose. So, let's start with this step-by-step guide.

• Download the app from the corresponding store, install it and open it.
• Continue as a guest, create or log in to your account.
• Register by setting up your email and password.
• Accept the terms and conditions of use.
• Optionally subscribe to the newsletter.
• Add the device by clicking the "+" icon in the upper right corner.
• Location service permission is required for automatic setup.
• Plug in the device => the app will search for the device.
• If automatic search doesn't work (as it didn't in my case), manually select the device => follow the instructions in the app.
• The connection will be established.
• Once the device is found (it worked for me now), give it an appropriate name and select an icon.
• Connect to WiFi.
• The installation is complete.
• Now, with just a few clicks, you can link your Meross account to Amazon Alexa or Google Home.
• After installation, you may receive a message that a new firmware is available, which may take a little while, but then you'll be up to date.
• You can now operate your new smart plug in the app and receive helpful information on power consumption.
   

Note: The firmware update takes quite a while. I have been waiting for a few minutes to continue my testing. During this process, the plug cannot be operated and should not be turned off. Another note: After waiting for over 10 minutes for the update to finish, I turned off the plug and restarted the app. The update had already been installed. Replicating this is at your own risk.

The installation of the Meross app was quickly done. A positive aspect of the Meross app is that it can be used without registration, but registration can also be completed in just a few steps. However, setting up the Meross WiFi plug was a bit bumpy. Initially, the automatic detection/installation did not work, resulting in manual selection/installation. Okay, I can live with that. Then the firmware update did not work immediately, and it never finished. After waiting for 10 minutes, I turned off the plug and closed the app. After that, everything worked again.

The app offers the following features in conjunction with the WiFi plug:

• Measuring energy consumption
• Changing device icon
• Defining device names
• Activation/deactivation of the status LED
• Direct link to the user manual
• Setting the time zone
• Location recognition
• Device time (info only)
• Quality of WiFi signal (info)
• Model number (info)
• Firmware version (info)
• Hardware version (info)
• MAC address (info)

The energy consumption is displayed on the device page (current power supply in watts and power consumption today in kWh) and can be viewed more precisely in charts in the detailed view (daily average and total consumption in three charts: last week, last month, and total time).
