I have been working with lighting control systems for about 10 years (factory certified and everything) now and our company is one of the few purely electrical contractors that does this (as opposed to the drive by night audio/video companies who often do these systems) so I say this with some authority on the subject. My suggestion would be to use high end products, even if it's a small job. There are tons of Home Depot/Radio Shack quality "automation" systems that work through the house's wiring or some other BS and every single one I've seen has failed and acted erratically. Wifi only devices also are unreliable because home networks go down all the time and you'd be at the mercy of the dreaded audio/video guy.
Because of that, I suggest Lutron's systems because they have FCC approval for their wireless systems and their stuff works for years. I still see Radio Ra Classic systems that were installed 15 years ago and they still work (though mechanically they look like crap after 15 years). Unfortunately (or fortunately depending on how you look at it), the fancier systems require factory training in order to be certified and be allowed to use the software to program them and you do need some basic computer skills and especially some networking basics.
It's funny that now days mainstream technology media are calling these "the internet of things" and acting as if home automation is new because these have been around for 20 years or even longer, but it used to be that only the wealthiest of customers (living in $5 million houses) could afford them and they were somewhat crude and required a lot of hard work customizing and programming. Some history:
The biggest names back then were Lutron's Homeworks and Litetouch and later Vantage Controls (which is one of my favorite systems) all of which required running low voltage cables to each keypad and dimmer (or dimming panel). Later Lutron came out with their Radio Ra system which was pretty much the first reliable automation system that was perfect for retrofit given that it was wireless. They also updated their Homeworks System to include wireless in addition to the panels. Later on, Audio/Video systems like Crestron got into the game too and have their own lighting system, but for sparkies I think that's the wrong path.
Anyway, I think if you're going to stick with one system, Lutron still offers the most bang for the buck because now they have their flagship Homeworks QS system (for very large installations in fancy homes) along with the new Radio-Ra2 system (for someone wanting to spend $2000-$30,000), and now they've come up with a gateway drug system called Caseta Wireless which doesn't have keypads for the wall, but lets you hook up much cheaper devices to an app and control things with timers or the app or little Pico switches. For less than $1000, you can do quite a lot and it's all very straight forward. You can even put the thermostat and shades on there too and you do the programming on the app which is free.
Personally, for anything more than 5 loads to 80 loads, I would recommend radio-ra2 and for bigger systems Homeworks QS or Vantage Infusion (man I love that system). For you, you can try Caseta and see how you like it and if it works out, get certified in Radio-ra.
I've been away from residential completely for quite some time now and i'm not up to speed on whats available.
I was at lowe's tonight with my friend, and we saw some devices that can be controlled via a network.
Anyway, she mentioned that one of her friends has lighting and temp controls that are operated via the iphone, and she would also like to have something like this.
What are the basic options now for simple lighting and temperature controls that can be operated via an iphone? Its worth noting that she doesn't have home internet or wifi networking; she just uses the phone for everything and makes it a hotspot when needed for the laptop, and i'm thinking this will be an issue. Setting up a wifi network to simply connect devices wouldn't be a problem, but idk how the iphone behaves on a network with no internet access. Does it remain connected for local use and fall back to cellular for internet access?
thanks for any help
