I use it to control some of the lights in my house. WiFi enabled plugs and switches are more convenient than having to go to each one and manually reprogram them. In my bedroom, I have one set to turn on every day at 7am and again at 9am in case I turn it off and go back to bed. It’s basically a silent alarm clock.
I also have WiFi control for the mini-split (AC and heat) in my workshop. I can view the set temperature vs the actual temperature from my phone and I can adjust the temperature remotely if I want.
On an episode of BBC’s: Planet Earth I saw an eagle grab a small goat, carry it off a cliff, and dropped it. Effective to be sure and kind of clever for the bird, but terrifying to watch.
