There is a wall mount included which attaches with sticky strips. The switch itself twists off the mount, allowing you to take it with you to be used as a remote control if you so choose.
This switch uses the kinetic energy from pressing the button to power itself. That means that it doesn't need to be plugged in, and you never have to worry about the batteries dying.
Because the kinetic energy from pressing the switch is used to power the switch itself, you really need to push the button hard in order to activate it, requiring much more force than regular switches.
When mounted on the wall, the switch looks futuristic. However, once you remove the switch the mount itself is left exposed. It looks like a smoke detector mount, except instead of hiding away on the ceiling it's generally going to be exposed on a highly visible wall.
There are 4 buttons on the Tap - one large main one which covers the entire front, and then 3 smaller buttons for additional scenes which can be custom configured through the app. Together, this switch allows for control of 4 separate scenes.
This switch only controls two lights at a time which need to be plugged into the switch. This also means that the switch itself needs to be plugged into a wall socket, which are typically low to the ground making the wall switch harder to reach.
Once all setup, you can turn off lights in each room and also each zone. For example, you could turn on just your bedroom lights, or the bedroom as well as any other room upstairs if you've included the bedroom in the upstairs zone.
If you sometimes want to use a physical remote instead of always using Siri, you can. The remote's battery is rated for 10 years. It comes with a mount which can be mounted to a table or the wall for extended control.
If you are away from home and want to turn on lights, or check to see if any lights are on, you will need an Apple TV. If you already have one, this isn't a big deal however for many out there this will add another device and another initial startup cost.
