Control from anywhere
Control lights, shades, fans and temperature in the comfort of your home or from anywhere in the world – the office, the airport, the beach – so lights aren't left on, shades aren't left open, and your HVAC is set back while you're away.

Make a scene
Add personalized scenes to control multiple lights and shades together at the touch of a button. Create a "movie" scene that dims the lights and closes the shades, or make a "goodnight" scene that turns off all your lights and closes your shades as you drift off to sleep.

Right on schedule
Schedule scenes to happen automatically at set times of day, or based on sunrise and sunset. Turn on your porch light at dusk, turn it off at dawn, or open your shades in the morning to wake up with the sun.

Automatically turn lights on when you arrive home and automatically turn lights off when you leave. Receive a notification if you’ve left the lights on after leaving home, then turn them off right from the Notifications screen.

Today Widget Scene Selection
Turn on your favorite scene from the Today Widget by swiping down from the top of your device's screen. No need to launch the app or even unlock your phone.

Apple Watch App
Control the lights and shades in your home no matter where you are. Whether you’re on the couch and want to dim the lights for movie night, or on the road and want to make it look like someone’s home, all it takes is a tap. And if the lights are on when you leave the house, you’ll get a notification giving you the option to turn them off. You can even close and open your shades while you are on vacation to give your house a lived in look right from your wrist.

HomeKit Support
Use Siri to control your Lutron lights and shades. If your iPhone is charging on your bedside table, simply say "Hey Siri, turn off my lights." Group your lights together into rooms so you can say things like "Siri, set the Kitchen lights to 50%." App developers can control Lutron dimmers, switches, and window shades.

Loading time

Takes a long time to load but otherwise works great. I like that you can set lights to turn off at a certain time in case you forget to turn them off. I also have my outside light set to turn on from sunset to sunrise. Works well with Alexa and customer service was awesome when I had some setup questions with the dimmers. Just wish the app would start up faster.

Update: loads a bit faster now but still not fast enough. I figured out got to add the today widget which is much faster to use. I recommend using that for the lights you use the most instead of opening the app.

Feature request: would love more flexibility in the schedule area, for one time needs (not repeating) such as: leave light on for the night (turn off at sunrise) and a timer like turn lights off in 3 hours. Thanks!

Siri phone works. Watch does not at first

Alexa will work but not as well as Siri. But Siri only works well with the iPhone. The watch does download the app but does not let you control anything. I had to delete My Home in HomeKit and reload the bridges to get it working. That is crazy. Also, the app watch does not let you access devices. It only lets you access scenes. So unless you create a scene you will not see your device. So create a scene to turn on a light and create a 2nd scene to turn off the light. Not very smart.

With all that said, I don’t think there is a better hardware device for switches. Add Hue Lights to Caseta and you have an amazing system.

The 30ft Range is not a problem for me yet but at a minimum they should create a mesh of Bridges that could add 50 devices each. So that with 3 Bridges one could handle 150 devices. 2 Bridges with 2 separate accounts is not an acceptable solution. And the expensive custom “RA2” which is a premium to the “Caseta” system is not HomeKit ready which means that even for free no one would want that outdated expensive system. Currently you can only do 50 switches on Caseta, which means you have to be selective on what to use Caseta. May be light switches using Caseta and use a different Brand to control power plugs.

Simply. Awesome.

The possibilities with this system are endless and I have a lot of different scenes set up and automatic scenes set as well. The right lighting levels in your home make all the difference in the world, and I have dimmers set that ensure my plant lights with plant lights around the house receive adequate lighting while I'm at work.

I never have any issues with the app and I can easily adjust lighting from my iPhone, iPads, even my Apple Watch in a pinch. And I have a few wireless remotes in the remote cradles and remotes mounted on walls with regular switch plates that work just light regular dimming light switches. I also have the hub which is key and it integrates with Apple HomeKit so you can let Siri adjust things for you too.

When friends and family come over they're seriously blown away - it's professional-grade. It's not exactly cheap, but I'm not looking for cheap - I want something that works flawlessly and that doesn't cost an arm and a leg either.

Switching lighting scenes couldn't be simpler. Combine that with auto shade adjustments and even temperature control and jaws drop. For me it's the ultimate convenience that I love, and being able to achieve the perfect lighting levels for every occasion.

I can't imagine going back to the days of constantly having to flip switches on and off around the house. I've tried others and this is by far the BEST. I love this system. I'd never go back - Look no further.
