and there are hundreds of hits. Some will have wireless connections that link to an app that gets sunset time from a network server, some have optical sensors that sense the darkness and turn the lights on, some have WiFi connections to a desktop app that triggers the outlets on and off.
Internet of Things, for the curious, would be stuff like your phone accessible doorbell camera or that mega-bucks fridge that can tell you when you're low on eggs. Or the Philips Hue lightbulbs you can change the colors of with an app.
I don't do that stuff because of privacy and security concerns. And also because I have learned the hard way that simple is better with Halloween (and life in general).
For lighting I use smartthings hub and use leviton in-wall and plug in units with "Z-Wave plus" as well as HUE bulbs in lamps and single light fixtures. Allows me to make much better use of my time and save a ton of energy.
just make sure you are aware of your wifi channels when using smart bulbs like hue or other things with zigbee control as the channel
