Honestly, that site you linked has a few different options but it really doesn’t provide any useful information. You could spend time researching each individual option, as many of us here have done, and land on one (as everyone here has done:)
I myself tried Staples Connect, Lowe’s Iris, and a Z-Wave Z-Stick with half a dozen different computer controllers. I landed on ST and haven’t looked back. It’s by far the simplest system I used while still being completely open. At $100, it’s not a break-your-budget price that once you dive into it’s hard to get out of (I’m looking at you HomeSeer). It’s up to you, but do your research. Everyone here is likely to be biased towards ST.
With mine, I have an alarm system that requires zero interaction from me to arm/disarm, and with no monthly fee. I have a temperature system that adjusts the temperature for my kids rooms at night when they’re asleep instead of in the main living area, but keeps the living area comfortable during the day. I have lights that turn on/off when I go down stairs in the middle of the night, and that don’t blind me. I have external front lights that turn on and off with the sunset/sunrise. I have others that turn off automatically when we go to bed - or several on at the same time through a single switch (multiple floors, one switch).
My thermostat turns off when we leave a door or window open too long. My garage door lets me know when I’ve left it open. My basement fan turns on when the humidity gets to high. I have an alert for extreme temperatures.
My door lock alerts me when someone else, who is authorized, enters the house. I have codes for family and friends.
I get a phone call while away from the house and the alarm is triggered, or a smoke detector goes off.
All of this took a little bit of a learning to achieve of course, but was all really easy thanks to the support of this community and it’s developers who make custom software available for free to others. I’m not a dev, but I can easily copy/paste as most steps require.
Best of all, 100% wife acceptance. She doesn’t have to do anything out of the ordinary, yet has complete peace of mind while I’m traveling.
I couldn’t do all the above with any of the other options I tried. They all had gaps, be it no zigbee support (some of the sensors) or addons for security, or secondary (or third) services required for text/email/phone calls. ST ties it all together in one easy to use package with a TON of support from the community, IFTTT, and even Amazon Echo. Lots of extendability, and really a limitless number of options.
You’ve got Z-Wave, ZigBee, Wifi, and Bluetooth support. All of the major standards in one $99 package. I know, I sound like an advertisement - but you did come to the ST forums to ask what we think
