Home Automation technologies have remained out of reach of the mainstream consumers for a long time. The high cost and custom installer requirements have restricted them to high end homes. The multitude of technologies in this space has also been detrimental to the adoption rate. However, the rise of smartphones and tablets has suddenly brought about a big shift in the landscape.

Wi-Fi networks have become ubiquitous in almost every home now. Smart device manufacturers have realized the advantages of integrating Wi-Fi instead of ZigBee or Z-Wave in their products. Some aspects such as power consumption, range and, to some extent, cost are still not optimal with Wi-Fi. However, with silicon vendors becoming active in this market segment and work progressing well on the 802.11ah front, these will be addressed soon.

In home automation terminology, 'scenes' refer to the linking of devices in intelligent ways based on events. Simple device-based control using a mobile app opens the door. But, one also needs a central device which can perform the orchestration. This makes it necessary for specialized HA protocols to have dedicated controllers. In a pure Wi-Fi based system, I can see this orchestration running as an app on the router. For example, Netgear allows third-party developers to write apps for their routers using Java and post them in the Genie marketplace. If the HA devices have open APIs and developer documentation, creation of scenes in a pure Wi-Fi based system will probably not require a dedicated controller.

What does all this mean for the average consumer? The most important takeaway is that home automation products, particularly Wi-Fi based ones, will see an uptick in adoption. This will, in turn, fuel the development of more innovative HA devices. This will be a boon for consumers who already have a HA system in place. What about users who are starting afresh? It is very important to not get tied down with a closed system. Products such as Nest and Belkin WeMo may boast of excellent industrial design and a great feature set. However, unless they open up the APIs and access for third parties to create a common custom home automation interface, they can't be recommended. Products such as those from Radio Thermostat and Visible Energy may not have great industrial design or the marketing budget that others have. However, we can recommend them without reservations for their feature set (including the well-documented APIs for developers).

A host of Wi-Fi enabled HA products and concepts have already started capturing the attention of the consumers. Coupled with the rapid rise in Wi-Fi based home automation, the talk of an 'Internet of Things' will soon become a mainstream reality.

    The market is fairly confusing for a non techie customer, We were about to buy 3 Z-Wave locks from Lowes for our home a few weeks back. But then I noticed the lock keypads are not really weatherproof(very important in the northeast), and there is a $12.99/month fee to access your locks online. What a load...

    $299.99 for the door kit and base station
    $129.99/additional door handle
    $12.99/mo for as long as you want access remotely to your home....

    We want:
    -3 outdoor weather resistant locks(only one will be under an overhang)
    -outdoor lights defaulted to motion detection, over ridden by secure mobile app or door locks
    -indoor lights that can be grouped by zones
    -cameras defaulted to motion detection, turned on anytime the doors are open, and overridden by secure mobile app
    -thermostat
    -All information stored on my own server, and accessible from mobile app.

    The wifes primary concern: wants to turn off everything and make sure the doors are locked from her Android tablet from bed when I'm out of town.

    ...any suggestions

    Could get a micasaverde (vera)

    Personally I don't find their ui very intuitive, but it supports a lot of devices and there are mobile apps with no monthly fee.

    I have one I've used for testing a few things but to be honest I don't even have it hooked up right now.

    I have an alarm panel module (ip datatel - bat) that lets you control your alarm system from an android or ios app and it works pretty well - my wife can use it. I believe it does have a low monthly fee (I have one for testing/work so I'm not paying personally), but it's nice enough.

    One of the things I do is write video surveillance software and so I dabble in home automation and alarm/sensor monitoring. I find many cheap ip cameras try to tie you into their software and online systems etc, but then fail to provide a complete solution (like what you are looking for). A full featured system like you are asking about... Is still hard to come by. Maybe somebody else knows one, but my own software, and any other software I have used (quite a few), don't provide everything you're looking for out of the box. But I don't work in the residential market so there may be a gem out there I just don't know about.

    Unfortunately, my smart meter was installed this year, and only supports Zigbee Smart Energy profile. Perhaps someone will build a converter to make it available via WiFi, but otherwise, it's locked into a very restricted license for access, such that it is quite expensive for a hacker to use. One has to get a key from a RIM subsidiary, and the first license is quite expensive. The license is likely restricted to devices which have passed Smart Energy profile certification, and I have no idea how much that will cost. So, if someone wants to build a WiFi to Zigbee converter box, I'd be happy to buy one. Reply

    I do not care to much about home automation. However, I have noticed myself to stand in front of my house pushing the car remote and wondering why the door does not unlock ;-)

    So I think the much more desired use is integration of technology by open standard. For most younger people the cell phone is the key to their life. So why not have the ability to use it as door opener, access badge at work, gym locker key, ATM card, car key (with seat memory and other setting preferences), ...

    The key to all this is the ability to register securely the user's device or the operational unit with the user's device. How does current home automation do this?

    Also, where is open source on this? I really can't see myself using a third party web service to access my house remotely? Next thing police forces them to open the door? So I want an open source based control server on my own hardware.

    Also one of the objects that many geeks want to remote control is their computer(s). What is the state of Wake on LAN to achieve this? Most of what I have seen is standard routers not having the feature.

    I have a zoned heating system with 3 zones. I probably could have gotten away with 2, but the third came with only the cost of an extra thermostat. Unfortunately, the zoning system provides no input to the HVAC system other than the 2 stage furnace or 2 stage air conditioner. Ideally, this would all feed back into the control board in the furnace, with information on how many zones need heat/cooling, the size of the zones, whether they are in the sun or not, and the outside temperature. This would allow better control over whether the second stage of the heat/AC is useful, and how fast the fan should run based on the number of open zones. A heating cycle could be extended if one zone was close to needing heat rather than more frequent furnace cycling which is hard on the heat exchanger. The set-points for each thermostat could be maintained in the control board, and controllable through a smart phone app or locally. But, the thermostat could really be reduced to just a temperature sensor with no user feedback. The NEST thermostat is an overly expensive device primarily because its combining a user interface, processor, controls, and temperature sensor. I would rather have the intelligence in the furnace control board (or blower control from outside the control board and intelligence in the HA system). Reply

    Essentially, for HA to really work, there's a higher level protocol that's going to be required. And this has to be standardized.
    There's currently a big push for this kind of thing, with many patents and standards being published, and I wouldn't recommend to anyone to invest heavily before this has somewhat settled down.

    Zigbee still seems to be THE M2M-technology according to what I see at work (M2M research lab at a large European telco), as it is much cheaper to implement than the heavier protocols.
    Future 802.11 might change this, but at this time, I'd put the focus there.

    Finally, until there are better presence /identification /activity sensors and the required logic to learn usage patterns, it will remain remote control. This is convenient, but it doesn't go far enough for me to truly adopt it. Never mind spending big money on it.

    For now it is still mostly faffing about with electronics, and in that case I would stick to rolling your own, in the most modular way possible, so that if eventually a consensus standard emerges, the USB of HA, you can swap out your interfaces, without touching the hardware.

    The market still is too cluttered to propose 'the standard' that will be the USB of HA, especially as most of the ones currently being offered are proprietary and heavily protected by licenses.

    I'd also like to point out that there is more going on/needs to be looked at for all those gadgets and helpers to be more efficient (resource usage).
    These days every little thing comes with it's own acdc converter if it needs non-neglible power for displays or actors, this means all over the place there are powerplugs with their inefficiencies and clutter. There is (afaik) no venture to standardize the powersupply of things in the 0.5W - 30W range.
    Ideal would be some kind of low voltage dc distribution network for each house/apartment that is standardized similar to 230VAC power distribution.
    But there is NOTHING going on there - and most importantly the sockets/plugs for this. NOTHING (besides some 600V DC plugs for server environments - google: 'datacenter VDC').
    And to tell you the truth, once you got this distribution network, it's easy to just pull some more wires along for some protocol/interface, which would even eliminate the need for wireless most of the time.
    That would be the USB of HA ;-)

    I have a rather nifty (nutty?!?) application of Home Automation that allows people on the Internet to control my Holiday displays at Halloween and Christmas - http://www.komar.org/cgi-bin/halloween_webcam and http://www.komar.org/cgi-bin/christmas_webcam

    These have been around for a while, so using X10 ... and oldie but goldie. Lotta various control & sensor stuff" out there (and cheap) ... but yea, is a bit slow and has some reliability issues ... although many of those can be addressed via some really cool devices from this guy - http://jvde.us/

    I'd love to go to a higher tech (and agree that it will converge on Wi-Fi) but am waiting for the marketplace to mature and stuff to get cheaper.

    Great overview of HA Ganesh!
