Compared to the Tap controller/switch, you're probably wondering why this switch requires batteries. Not to worry, one battery will last at least 3 years before it needs replacing. Better yet, a battery is included, so with purchase you will be go to go with controlling your lights!
The Tap should be able to communicate with the Bridge at least 39 ft away. If in doubt, take some rough measurements from your Bridge to the location you plan on mounting the switch. If you are looking for a remote like switch/controller, take a look at the Tap.
