Amazon has GE's Z-Wave Compatible Smart Lighting Control Light Switch available today for just $29.32. This is typically priced at $39.99, so that's a pretty good price, knocking nearly a quarter of its price off. If you are looking to get started in the smart home space, this is a great place to get started.
This product from GE works with Z-Wave, which has a ton of other compatible products, and also works with Amazon Alexa and Google Assistant. But it is also an easy way to turn your existing lights into smart lights. For instance, say you have ceiling lights in your living room. Instead of replacing each bulb with a smart bulb, you can simply install this switch and every light that works on the switch will be smart now. This means you can use an app to control them, but also use your voice with Amazon Alexa, Google Assistant (and even Siri, if you have some Apple products laying around), to turn these lights on or off. Of course, you can also use the app to set different timers for these lights, so that they will turn on in the evening when the sun starts to go down, or just before you get home from work. This price is not going to last long though, so if you do want to pick up the GE Z-Wave Plus Smart Lighting Control Light Switch, you'll want to do it now.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year (or $49/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
