Where is the best place to put plug?
Please use the plug only for sockets that are easily accessible(with a maximum distance of 50m to its base). You can then disconnect the plug quickly and easily from the power supply if an incident happens.
The location of your plug depends on the electrical device you would like to steer with your smartphone. After its registration in the system plug works as an adapter; so you should use it as a connection between the power socket and the device. Now you can turn it on and off separately or set up a schedule for the automated switching of your device´s power supply.
