I've begun dabbling with (very basic) home automation, but I'm doing the exact opposite of everyone else in this thread: I set up everything for control via my Echo devices, and I only use hardware which requires no hub. My story so far:
Back in August, I received an Echo Dot as a gift. I set it up and began doing the usual things with it (especially music streaming), and quickly decided it was a neat little device. In October, I bought one as a gift for my sister back in Ohio. Together, we decided our parents and every sibling needed one in their homes; we planned to offer them as Christmas gifts. On top of that, I wanted a second Dot for myself. In December, Amazon had a deal: the Dot itself was only $29, or you could bundle one TP Link smart plug with it for only $5 more... so I bought three bundles, gifted two Dots as planned, and kept one Dot + all three plugs for myself. That gave me three of these:
Now I had my first smart devices, even if they were just simple plugs. They were easy to set up (no hub required) and they all work flawlessly. The only downside is their form factor: their housing is so large that it prevents you from being able to use the other plug on that wall outlet. But if you can live with that, they're great. I used one to control the Christmas tree lights, one for a standing lamp in the bedroom, and one for the radio in my kitchen.
A co-worker with an Echo Dot (and some home automation hardware) heard me complain about the form factor of these TP Link plugs. As a Christmas surprise, he and his wife gifted me one iHome smart plug:
This was also easy to set up, and it also required no hub for Echo integration. Best of all, its shape allows you to use the other plug in that outlet. Nice. I installed this smart plug in my garage, allowing it to control an overhead light while also leaving room to power the garage door opener via the same outlet. (In the past, I always had to drag a chair across the garage, then stand on it and physically plug in this light whenever I wanted it on. This newfound convenience was very welcome.)
I decided I could use another pair of plugs of this shape inside the house, so I went to Amazon and bought a 2-pack of Jinvoo plugs:
I had one minor hiccup getting them to configure (which I blamed on the Chinglish instructions), but eventually they both came online and have worked perfectly ever since. No hub was required for these, either. I swapped one to control that same standup lamp in my bedroom; the other was placed in the same outlet to control a light I just installed in the closet. (I've wanted a light in there forever.)
Just a couple weeks ago while browsing at an 'odd lots' type outlet store, I randomly found
one iHome smart plug plus
one Smart Life smart bulb, both for very cheap. I was already familiar with the plug, of course; recognizing its price as a great deal, I happily snapped it up. The bulb's box was nearly devoid of any technical information whatsoever, but it was so cheap ($6) I bought it on principle alone. It worked with my Echo without needing a hub, and I got it up and running quickly. I soon discovered it is dimmable, which I was kinda hoping for anyway. But what surprised me was when I gave it a command and it suddenly turned red. A rainbow bulb! For only six bucks! Now I was mad that they didn't have any more of them.
To test that theory, I returned to that store a week later. No luck, there were no more of the rainbow bulbs. However, I did find
one TP Link smart bulb. I knew it was definitely not a rainbow bulb, but at $9 it was still a solid deal compared to the $22 cost at Amazon so I bought it. It has since been installed in my laundry alcove, where it can also double as a hallway/night light when I want to illuminate via voice control.
As you can see, everything I do is all about voice control. If I'm headed to bed for the night, I can turn on lights at that end of the house so I don't risk stubbing a toe on the way there. I can climb into bed, and then turn off the lights after I'm settled in. If I'm in bed and I suddenly realize I forgot to do something, I can just tell my Echo to remind me in the morning. As I listen to the radio in the morning while getting ready for work, I can turn on the kitchen radio as I head down the hall so I don't miss any part of the joke/news story/whatever. I can stream music at either end of the house, or both simultaneously if I think I may go back and forth.
Anyway, that's how far I've come to date. After reading this thread, you guys have me wondering if I can find some inexpensive motion sensors.
