Disappointment
The socket works correctly, the installation is relatively easy.
However, the operating distance between the box and the socket is too small.
By comparison my DSP-215 is much more reliable and its operating distance between the box and the socket is in my case 8 m with 2 breeze block walls between.
I had to swap the two sockets to compensate for this problem. Moreover, I need an additional "Mydlink" application to operate the DSCP-W115 socket.
This new application is too slow and does not support the DSP-215 socket.
One application per socket, it's stupid.
The only positive point is that it can be controlled via IFTTT
