A home automation controller (and/or software, and/or interface) is essential for remote access and control of your home automation devices (or peripherals) from a computer, smartphone or tablet. This remote access isn't limited to control from inside your home, it usually allows you access to devices from anywhere in the world so long as you have access to the Internet. That means you can control almost anything remotely - turn lights or appliances on and off, open door locks, shut the garage, monitor energy use, check temperature and humidity sensors or even have motion detectors notify you instantly if movement is detected on your property.

Selecting the right home automation controller can be a slightly daunting task, as there are several controllers to choose from - each of which has several features to consider, Technology, Devices and Function. After reviewing the information in the tabs on these features below, you can then select the Controllers tab to choose the right controller for your application in a connected home automation environment.


When choosing a controller, an important consideration is the technology that is available and what you feel best suits your needs. Generally speaking, when we speak of technology, we are referring to the type of communication and/or protocol that is being used to allow different devices to "talk" to each other. Some controllers use hardwired communication over your home power lines such as X10 and UPB; some use Radio Frequency (RF) or Wi-Fi to wirelessly communicate such as Z-Wave, Zigbee, WeMo, SkylinkHome and LevNet RF; while INSTEON uses both power line and radio frequency to ensure greater reliability. Some controllers are specific to a certain type of technology while other controllers support various technologies, so take a look at a combination of the technology you like and devices you will be using to find the controller.


INSTEON is the best-selling, most-reliable home control and automation technology. Using dual-band technology, both the existing wires (power line) and radio-frequency (RF) communication, INSTEON home automation devices add remote control and automation to lighting, appliance and home control applications of all types. From lighting control to integrated security systems, the gold-standard in home automation allows you to manage your home the way you want. Easy to install and setup, INSTEON offers the flexibility and dependability to make your life more convenient, safe and fun.

INSTEON is the only dual-band home networking technology. With every INSTEON-enabled device being a repeater, messages are repeated (if and as required) simultaneously by every node in the network, so the signal gets stronger with every added device. INSTEON is the least complex of the network infrastructures, ideal for DIY. INSTEON products are fully backward, and forward compatible. INSTEON messages get through in less than 0.05 seconds - faster than the human eye can detect, so there are no visible delays. A complete INSTEON-enabled system costs a fraction of its competitors.

A detailed technical comparison of INSTEON and other top technologies is also available.

The devices (also known as peripherals or modules) you plan to use will also have an impact on the type of home automation controller you will want to purchase. Devices are the things that are triggered to perform an action by a controller, send feedback or data to a controller, or sometimes do both. Common devices include light switches and plug in modules, through a controller you can remotely turn these on and off. Other simple devices include sensors which could provide you feedback and send you an alert if motion is detected or a door is opened. You can even combine some of these devices to create scenes, for example if motion is sensed, trigger a light switch and a plug in lamp to turn on. Advanced devices like thermostats allow you the remotely turn your HVAC on, or you can even schedule your sprinkler system with relay modules.

Dimmers, Switches, Outlets, Sensors & Timers

You will find all of the most common home automation devices in the Dimmers, Switches, Outlets, Sensors & Timers category. Within the category are 4 main device types: in-wall devices, plug-in devices, screw-in devices and wire-in devices .

In-wall devices primarily include hardwired traditional and decorator-style switches most commonly used for switching lights and appliances on and off. These include dimmer switches, on/off switches, sensor switches, timers switches, combination switches, and keypads.

Plug-in devices are exactly the what the name implies - modules that you plug into an outlet that allow you to switch lights and appliances on and off. These include dimmer modules , on/off modules, sensor modules, timers modules, and keypad modules.

Screw-in devices are mostly modules that screw into a existing lamp light bulb socket and provide added control over that socket, from simple dimming to control from a wireless switch, motion sensor, or from a home automation controller.

Wire-in devices are less common hardwired products and include a variety of modules such as outlets, in-line dimmers, in-line on/off switches, in-line timers, and heavy-duty timers.

The next series of factors to consider when choosing a home automation controller is the functionality of the product. Depending on your application you may not need a controller with high end functionality such as voice control capability or access to a remote security monitoring service. Your needs might be as simple as a system with remote access and wireless devices for easier installations. Others might require the reliability of a wired system along with programmable actions and schedules to create an energy efficient environment. Functionality also includes the compatibility with things like your router or smart devices.

Ease of Use

Many higher end systems like Crestron, Lutron RadioRA and Control4 practically require a degree in programming or a technician/representative to update or make changes to your system, both costing time and money. While some prefer this hands off approach, it is not very user-friendly. The ability to add devices, link devices, program devices, and the interface you use to perform these tasks is what will determine the level of ease with which a home automation system operates. INSTEON Hub and Revolv are great examples of controllers with a very user-friendly interface and setup approach, while ISY994i controllers offer a less intuitive interface but a more comprehensive approach to programming. If you like the convenience of control from a smartphone or tablet that is also important as some interfaces only operate via computer.

Wireless/Wired System

If you are installing your own home automation system, consider whether or not you want a wireless or wired system...or both, this will help determine the type of controller you will need. Wireless systems usually install much more quickly but often have some limitations including communication distance and how susceptible they are to interference when communicating. Wired systems take longer to install, are generally more reliable than wireless systems, but may also be susceptible to interference from other devices over powerline. For the ultimate in reliablity, systems like INSTEON use a combination of wireless and wired devices.

The idea of versatility really piggybacks off of whether or not you want to use wireless or wired devices, or a combination of the two. If you want to use a combination of the two, and maybe devices from different manufacturers using different protocols, you will need a controller that supports that. If you want to use a combination of INSTEON and Z-wave products as an example, you will want to make sure you choose a controller such as the VERA3 controller which will support both, allowing you to link and program these devices together from a single interface.

Does your system require a professional to install and support it? or can't it be done by a DIY'r. Depending on your electrical experience Smarthome recommends that you consult a professional for the installation of any system that requires a hardwired installation. That being said, some controllers do the work for you when identifying devices on your network, so you can easily add and remove devices as you go. Identify how each system you are considering will be installed and what type of maintenance, if any, is required.

Even if you are starting small, try to think long term as to whether or not you plan on having a just a few devices, or a couple hundred devices. Each controller you look at will have a specific amount of devices and/or programs that it will support. The number of devices combined with the number or programs or events you have configured can add up quick, and the last thing you will want is system that is maxed out with no room to grow.

Do you want to turn on your bedside lamp automatically to help wake you up in the morning? How about turn the porch light on and off automatically with the rise and fall of the sun? Maybe you want to create scene so tha tyou can have all the lights dim when you watch a movie. When it comes to home automation the possibilities are almost limitless...but you need the right controller, Usually the least expensive controller offer the fewest features, which is fine for some who simply want to have things turn on and off at certain times. But if you want to link several devices to create scenes, or program your home to react to various events, or create other advanced macros, you will want to ensure that the type of programming you want to do is available.

Remote Access

If you are constantly on the go, you may want a system that works in combination with your router and smartphone or tablet to control devices in your home while you're there or when you're at work and on vacation. Most of the these controllers will also work on any web-enabled computer or laptop; however the reverse is not always true, some controllers will work on a computer or laptop, but do not have app integration for a smartphone or tablet. Also, some controllers offer only limited control from the web, meaning it may offer simple control such as turning lights on or off, but will not allow advanced programming such as setting timers or creating scenes. Decide what suits your needs and look closely to make sure the controller you select supports those needs when it comes to remotely accessing your system.

Today, home automaton means more than you just controlling devices in your home, it also means having those devices communicate back to you. You may want to receive alerts from leak sensors, motion sensors, door/window sensors, smoke detectors and more. Many of these controllers now send text and email alerts to you, as well as anyone else you wish, when the status has changed; or you can remotely check the status of these sensors. These features are great for families and small businesses so you can track such things as what time people come home, who has unlocked the door, if an intruder is detected, when a window is opened, or if there is a potential hazard such as a broken pipe or a fire. If any of these are important, you will want to make sure your controller offers a messaging feature.

Monitoring Service

Some systems either offer or require a monitoring service. Often these are systems that incorporate security devices into their features, such as 2GIG. The benefit of these services is that if you aren't home, or if you are asleep, they can notify the proper authorities in the event of a break-in, or possible fire or leak. This service usually comes at a cost however, so determine up front whether or not this type of service is of value to you and choose a controller that fits your needs..

Help & Support

Home automation covers such a wide variety of options when it comes to using different protocols, devices and applications, that you will surely run into some issues along the way. That being said, when you have a problem, you'll want to know what your customer service options are. Does the manufacturer offer support channels that include live chat, telephone and email communication? How about online documentation including installation guides, user manuals, or video tutorials? Is there a forum to talk with other users? If you plan on putting together a robust system, make sure the controller you select has the support system in place to address all potential problems.
