Install by tapping in to the wires going to your PC switch. Set for momentary, download the app and your all set. FYI, you use the app to configure it, but you can use a smart speaker to control after it's configured. You can also turn it off and on via voice if you have a smart speaker like an Echo. BTW, when you activate it, if the PC is already on it will turn it off. For just a phone without a smart speaker, just search for wake on lan.
