With these switches, from the comfort of my desk at work, I can view which lights in the house are on (always the basement) and which lights are off (which are always the upstairs lights). Then, using either my voice via the Google Assistant or the app on my phone, I turn off one or all of the lights. It's super easy. It is not about laziness, it's about being cost-effective.
I also found it nice to turn on my outside lights or my garage lights when I am on my way home using my voice so I can see when I enter my home. It has an extraordinary amount of applications.
Installation was a breeze, once you identify your load and line wires. Their instructions and wire labels help a lot. Get a pen tester. They are cheap, super easy to use, WILL save you from getting shocked someday, and identify immediately which line is coming into your home. Also, before you order, turn off your breaker, open up your current switch you want to replace, and verify you have a set of common (usually white) wires. This will not work without them. It is very important that you make sure the switch you are replacing is the ONLY switch to turn the light on or off. If two switches turn a light in or off, you will need a 3-way switch. These are not 3-way switches, though this manufacturer does sell them.
If you just read that last paragraph and feel like this is over your head, it isn't. Though replacing some switches are much harder than others, most of the time it is a breeze. I say this as someone who knows nothing about electrical wiring. If I can figure it out, so can you. 3-way switches are another beast entirely, however. I'm pretty sure those ones function entirely off of witchcraft. As I am not trained in the dark arts, I will stick to these switches.
Oh, and don't forget to turn your breaker back on.
