Utilities: Lights, Power, Heating, Actions!

Play puppetmaster with your home's utilities from your Mac and iPhone, and reap the benefits of convenience and efficiency.
Light Your Way
Lighting automation puts the “utilitarian” into home-utility automation. These upgrades are flashy only on a literal level; you probably won’t go bragging to coworkers about how your House of the Future can turn its lights on and off. But these techniques form the foundation of home automation and make a great place to kick things off.
For starters, try teaching your house to turn on the lights as you pull into the driveway. In addition to a basic home-control setup with Mac software and a hardware interface, you can add driveway-sensor modules ($169.99) or an automation-savvy garage-door retrofit ($71.99). Or just get a new garage-door opener ($189) with a Z-Wave interface to both control and monitor the door. With your Mac software, you can then build an if-then script that ties into your home lighting. If a car pulls into the driveway, activate the exterior house lighting. If you open the garage door, turn on the entryway lights inside.

XTension lets you graphically assign icons that match your home setting.
More sensors can create additional options. An outdoor motion sensor with floodlights ($54.88) can turn on when someone passes by. Your Mac could then log the time it happened and snap a webcam picture of your yard.
You can take the process indoors, activating room lighting based on a motion sensor ($34.99). Full indoor automation can be harder since you might want to lounge around, but sitting without moving would turn the lights off. Still, it can work well in certain situations, such as lighting up a party as it moves around into different rooms.
Control Utilities and Devices Over the Internet
Most home automation software can connect online, letting you control devices from anywhere. Cancel your sprinkler schedule on a rainy day, open the shades in your teenager’s room at noon, adjust your thermostat when away, and otherwise tap into your setup over the Internet. Indigo and Thinking Home (see above for details) enable a web server within the automation interface. XTension uses an optional plug-in, X2Web ($39.95), to connect online.

Indigo Touch, a free iPhone app, lets you change home-heating conditions from wherever you are.
You could also remotely connect to an online Mac and control the whole computer as if you were sitting at home, directly using the automation software of your choice. Several remote-access tools enable this approach, including GoToMyPC ($19.95/month) and LogMeIn Free (free). LogMeIn even offers an iPhone version of the app, LogMeIn Ignition ($29.99). Or if you’re on MobileMe ($99/year), the Back to My Mac feature does the same thing. These tools might also be easier alternatives to setting up online components in the automation software because you shouldn’t have to make special network configurations on your home router to allow access.

Open-ended plugs, such as the EZ102X4 (top) and the ApplianceLink V2, let you connect any device to your automation network.
And many iPhone apps offer another way to connect to your hardware over the Internet. Indigo Touch (free) is a companion for that desktop software. Otherwise, just search for “X10,” “Insteon,” or “home automation” to browse the App Store. Be sure to read the requirements closely--some interface with software on your home Mac, while others talk directly to certain Internet-enabled automation controllers.
Create Your Own Animal House
You can more easily take good care of your pets in an automated house, especially if you’re coming home late or taking a short vacation. Some hardware ties directly into your setup, while you might have to creatively hack other devices.
For occasional meals, consider an internet-connected device, such as the Petwatch feeder ($269.99). The hardware includes a webcam so you can view your pet wherever you are.

With this Petwatch feeder, you can watch and feed your pets remotely.
If you’re technically minded--or you can draft someone who is--get creative with other home automation devices for great pet combinations. Some pet doors unlock when Fido or Whiskers get close; their collars hold a key. For one option, try a Solo Pet Door ($395 and up). This device retracts when it senses a magnet that your pet wears.
We couldn’t track down any pet doors that talk to home automation systems, but you can combine a door like this with your own sensors. Add a proximity sensor and webcam to track and record your pet movement; you could even have your Mac email or SMS a picture. If you add a power relay to the mix, such as the EZIO2X4 ($134.99) or Insteon ApplianceLink V2 ($34.99), you can lock the door remotely. Maybe you want to give your pets access depending on the time of day. Or you could lock the door after a cat returns from a night of carousing.

Use Home Control To Live Greener
A home-control system can also help you to reduce your carbon footprint and use previous resources more efficiently. Here are six ways to get started:
>> Rather than leaving your exterior lights on all day so your home isn’t dark when you get home, retrofit your light switches and use home-control software to turn them on when the sun sets.
>> Conserve water by installing programmable sprinkler controllers that can adjust their irrigation schedules in response to weather conditions and forecasts.
>> Create a vacation “scene” that turns your HVAC system off while you’re away. The system can also turn various lights on in the evening and off at night, using a randomized pattern that will fool prospective thieves into thinking the house is occupied.
>> Install a programmable thermostat that turns your climate-control system off 30 minutes before you leave and 30 minutes before you’re scheduled to return home. Use your iPhone to remotely update the routine should your plans change.
>> Reduce your electrical consumption and improve your media-room ambience by installing a dimmer that brings down the lights when you press Play on your remote control.
>> Add an Insteon-enabled 220-volt control to your current high-voltage electrical appliances, such as a water heater (a notorious energy-waster), and conserve money and power by shutting them down during the day or when you’re away from home for extended periods.
