You should read these instructions carefully. There are two before and after graphs, one for the load side and one for the line side. This confused me and made me think that the switch can be installed anywhere and the instructions depend on that. no The instructions show how to rewire a regular old fashioned 3 position switch on the line side. It is very important. You need to rewire this switch as shown in the picture. Then the standard installation of a new WiFi switch on the load side will do if you have a neutral wire. You will also need to rewire the original switch that you are not replacing. Then it works without WLAN or via app, voice control (Alexa) etc.
