Feit Electric Wi-Fi Smart Dimmer Switch 2-pack provides wireless control of your home lighting through the Feit Electric app, Amazon Alexa, or Google Assistant. These versatile dimmers can be installed as single pole switches to control lights from one location, or as 3-way switches to control lights from two different locations. The dimmers feature up and down buttons for manual brightness adjustment with indicator lights showing the current dimming level. They support dimmable LED bulbs up to 150 watts and incandescent bulbs up to 450 watts. Installation requires a neutral wire for proper operation. The dimmers include a lowest dimming point adjustment feature to eliminate flickering with compatible dimmable bulbs. Each dimmer has a power indicator button to turn lights on or off, and the brightness can be controlled remotely via smartphone app or voice commands. The switches can be configured to work with two smart dimmers on the same circuit, or paired with a regular switch for 3-way applications. Operating temperature range is -13°F to 125°F.
