New Home Automation? 336
An anonymous reader writes "Ok, fellow geeks... I have the luxury of finally building my dream home from scratch. It's going to be good sized (~4000 sq ft over 3 levels), and rather than run around at night to make sure my lights are off, doors are locked, garage is closed, etc, I really want to put in a home automation system. Since the walls aren't up, this is the time for complete flexibility as to my options. The last time I did a whole house, it was years ago, X10. Since then, lots of other protocols, both 'proprietary' and more general (like WiFi) have come on the market for devices — all better than what I've worked with in the past. What do you all have experience with and recommend as reliable, secure, and fairly easy to use? Something with a good chance for long term availability of parts and features would be a bonus."

Start using them by running two CAT-6, a pair of multimode, and if you can afford it (4000ft2?) a pair of singlemode fiber. Don't need to connect them yet, just have enough space for outlets.
At least two of these conduits per room, opposite walls/corners. At least one conduit to each outside wall of the house (put power in these ones too, not everything is PoE). Maybe one more conduit to the top of each outside wall if you want to add cameras-over-IP out of reach, while keeping regular plugs low.
Ideally you'd have all the conduits lead to two different rooms/closets/hidden_panels, in case you have to modify the house in the future, or if you expect people to come grabbing, whether they knock with a warrant or break the window.

If this slashdotter has a significant other (at 4000ft2, you'd hope), that may not be a negligible thing. Not having to spend a few hours measuring and pulling it (unless you terminate your own fiber) may make it worth having a few strands that will never be used.

Don't forget outside! At the very *least*, run conduit to the end of the driveway if it's any length - at least two, so you can run power and low voltage stuff (code usually forbids running both in the same conduit). Access for the deck etc also useful.
It doesn't hurt to run some other access points out the house as well, to help with future dev. I put in a carport, and the *one* available conduit coming out of the house made power and a camera possible. We have concrete sidewalk al around the house, so getting wires from the outside to the inside is very difficult now.
For music / audio about the house, you usually want access to the ceiling of each room, so you might want to think about conduit for that as well. Our house had wire installed, but not the right type - we had to live with it since I didn't want to rip out ceilings and walls everywhere.

Re:conduit in anticipation (Score:5, Informative)
I work for a company who installs automation here in Australia (Mox BI VIC). Firstly, the good thing is that you have the opportunity to decide how you want to wire things now if the house isn't built.
1) Start by Wiring back the TPS for lights, downlights, and power points to a single rack. This means that you wont need to crack open the wall to change to a new tech in the future, even if you plan to use a retrofitable system. I cry a little when I see a new house being built, and a retrofitable technology tacked on. Structuring the wiring will make all the difference in the future.
2) Wireless technologies such as Z-Wave are great, however, keep in mind that technologies running on 2.4GHZ need to accept interference. If the idiot neighbors run a baby monitor on those frequencies, and you get dropouts, you cannot sue them, or force them to change. For that reason, only use wireless technologies for retrofits if possible (for multicolored lights, they may need to realistically be wireless though). Do not design a system that will rely on it (except for iPad/iPhone AV control).
3), Run more CAT5/CAT6 than you think you need. And keep in mind, CAT6A theoretically can run up to 10gbit/s up to 37m. There is higher quality unofficial standards such as CAT7A available, however, only install them if you have the money (because, they aren't official, and may not add any real benefit, but are nice to have).
4) Have a 15A socket in the garage. UPS's work better with it, and, in an automated home, it might be nice to have control of some features.. Also, try to get a high-amperage TPS run to the garage (for electric cars potentially in the future).
5) Single story house is TONS less painful for future changes than double. If you are doing double, be doubly sure that the wiring downstairs is right. You might not get a second chance without tearing serious holes in plaster (which we have had to do in a few systems to add/change extra functionality the client later wanted).
6) Run at least 3 Ethernets to every TV. You might want a matrix switch later, and you may also want to control your TV's. If you run a single CAT5 to each TV, you might regret it..
7) You might want electric blinds... Keep that in mind.. You may also want gate lock and front/back door to be openable via intercom.
8) The last problem is wall switches. Unfortunately, many common protocols at this time use a Bus wired system (we use CANBUS, which is utilised in cars also). If you run 6-core security wire in a chain to each point, and RJ45 back to the central rack, you should be covered (albeit, in an expensive way).
9) Pick a standard with an open protocol. To be honest, many protocols can be reverse engineered (it just takes time). If you have the protocol though, even if you pick a standard that dies, it may be possible to develop a software bridge that bridges between 2 protocols, and slowly phase parts of the system out.
Obviously, I am biased, but I recommend MOX Canbus (as I know MOX is committed to the system for the long haul), but, ultimately, the system you choose will also depend on your country anyway (because, it needs to be electrically approved in that country anyway).

Z-Wave is entirely RF-based and requires no wiring. However make sure you have plenty of Ethernet everywhere because you will want to have Ethernet-connected sensors such as the power meter, the solar inverter, and a bunch more - plan for those ahead of time.
Plan also for video cameras for security and Ethernet cables to them for IP (or coaxial cables if you pick analog cameras.) You will need entry/exit keypad controllers to operate things (don't know what kind of property you got.) Basically, plan everything before they are done with framing.

You want this for Z-wave also. There are two-wire Z-wave switches, but they usually require an incandescent bulb. To expand on this a bit - make sure that lighting switches are wired with a constant hot and neutral, and separate load wiring. Usually this means the line and load's neutrals and grounds are tied together in the switch box, and the hot is switched. There are some other more creative ways to do lighting circuits that make things more of a pain when trying to replace switches.
If you can, get the electrician to label the load wire (the one that runs to the light). That can sometimes be a pain to figure out if there's only line and load in a single gang box. I also second the suggestion for alarm wiring. Figure you want motion sensors and wires to every door and window run to some central location. Changing the batteries on these is a big pain if you have a lot of sensors, and the sensors can also be part of your automation logic.

I wouldn't bother pulling coax unless you have a known use for it -- all of my video comes in over IP (delivered wirelessly to the TV's).

Conduits between rooms, with pull strings, would be very useful. But you need to plan for those access panels. If the switches need to be installed, one should plan for those too. I have no such conduits, outside of the cable that is already in place, and some rooms are missing network. My phones are all SIP (and one DECT wireless phone on an SIP adapter,) all connected to 3CX, so network is required everywhere. Wireless is not an option, you need cable.
Wireless is still an option, even with SIP -- I spent 2 years in a place where the SIP phone in the living room ran on the same wireless bridge that fed the TV.

The wires will be the same as your ethernet in case you ever change your mind, but if you design it right, you won't need to.
You rarely see any theaters, hotels, or shopping malls using anything else but ANSI/TIA/EIA-485.
Use KNX as your system (Score:3)
I did a huge amount of research on what system to go for when I was looking at doing the same.
The final result was that KNX represents the best system to go for. It is the only open standard meaning you have many many manufactures (as opposed to CBUS) it integrates with pc systems allowing you to do 100% customisable setups and its wiring is simple.
You have to run a seperate cable to every device you control but given you are building this is easy. The cable can support (off the top of my head) 128 devices on one cable. Each device is individually addressed and the on/off status is reported back meaning you can still use manual style switches with no problems.
As others have mentioned make sure you data wire your house as well while you are there but this is a different question.
Expect however to spend $20k+ if you are going lights, access, hvac, sensors, etc. If you want to keep your costs low during the build period run the cable where ever it is needed and add the devices later.

Reliability over Gadgetry, I say (Score:3)
People really put in a lot of money to save people. Automation in it's current state aint gonna save you a dime (especially lights and crap) and cause a lot of headaches when it comes time to fix. Especially light switches where the ~$1 switches are damn reliable tech.
I have all sort of low tech solutions, but for lighting, I recommend fixtures that take a normal A19 edison bulb. People always want to put in fancy flurorescent lights (not CFLs, just the odd shaped pieces) but the bulbs are always more expensive and never advance. With the standard A19, you can be assured of being able to buy the latest and highest variety tech. If you like track lights, you can buy A19 track light fixtures as well pretty cheap if you look around that look fine (as low as $5 ebay sales new, $7-9 normal)
Then buy 60w Cree light bulbs at Home Depot, they are the best and with subsidies, they cost $8 a piece in my area (down from $13 unsubsidized).
Unlike CFLs, they are instant on, use a few watts less electricity, and look normal. And the 2700k watt variety should attract less bugs (no ultraviolet emmittage) but that shouldn't be conflated with no bugs.
I installed lights, noticed the reflectors were less than optimal in ceiling lights and outdoor lights, that the 60w just wasn't strong enough, used a hightech item from the supermarket known as aluminum foil, placed it strategically and hidden from normal view and was able to get more light than 100w equivalent (23w) CFLs or 100w incandescent. My kitchen went from 256 watts fluorescent tubes to 76w ceiling lights (mostly because the tubes were typically places in center of the room trying to light be sheer power whereas the ceiling lights were placed accordingly). My living room went from 69 watt CFLs to 28.5w cree leds with the same lighting just because of aluminum foil.
My greater point is that aluminum foil and other simple stuff is much more reliable than fancy gadgets that turn things off every once in a while
You can also consider light switch motion detectors, but they too are expensive but at least it's a single point of failure and can be replaced with a standard switch should things go wrong.
The only tech I would really use is a good thermostat.
Talking about that, if you have any interest in solar and the like, look into David W. Allan's home in Colorado, situated 6000 ft high, that uses only solar passive heating.

What I've learnt from automating my own home (Score:4, Interesting)
I've nearly gone as far as I can automating systems and devices my current home - temperature & humidity sensing in most rooms, motion sensing in every room, zoned ducted evaporative aircon, a couple of split reverse cycle aircons, z-wave lighting and exhaust fans, and mains power monitoring.
-- Lighting ---
Z-Wave works mostly well enough, and I use this to automatically turn on lights when motion is detected, turn off lights after a while with no motion, or turn off when I go to bed. Unfortunately the turn-on the signal can take up to several seconds on a large 1-wire network, so even when the motion sensor triggers quickly you can still be halfway across a room before the lights turn on which is a pain. On top of that, I cant disable the z-wave dimmer soft-on and soft-off feature which is a pain when you're trying to get quick response. For the turn off, it's probably not worth it since I upgraded to LED lights as the power saved is negligible.
At the price of parts + install being $150 - $200 per light fixture it's not really been worth. A few minor conveniences and a lot of annoyances. I think I'd be better off with no automation on most regular light fixtures, and just some inline z-wave switches on frestanding lamps and mood lighting. Maybe automation on the living room and master bedroom for convenience / scenes.
-- Temperature / Humidity ---
Temperature and humidity sensing in every room has been great. In Australia where I live it's quite uncommon to have a whole house climate control system, so I've used these to help come up with a automated strategy for every room that integrates the available air conditioning systems. Also I've used the temperature, humidity and (calculated) air speed in each room to create a "feels like" temperature. Controlling against this rather than the dry air temp has given a much better result.
I've been using 1-wire devices as sensors, which need 1 or 2 twisted pairs for comms and power - cat5 is great. The DS18B20 temperature sensors are very cheap, have been very reliable and can send signals over long distances. Unfortunately the DS2438 based humidity sensors are not as good and I've had to partition the network a 1-Wire hub. Currently I still have intermittent errors with just 30m of cable on each DS2438 leg, whereas the DS18B20 temperature sensors could cope with a load of 100m plus. If I was building a new house I'm not sure if I'd use them again due to the issues with humidity sensing, but I'm not convinced there's many other affordable alternatives either. For reference the DS18B20 sensors are costing me about $2 each, and the DS2438 based humidity sensors (using a Honeywell humidity IC) are about $20 each from parts. Since I work as a control engineer, my next preferred option would be modbus slave devices over RS485.
-- Air conditioning ---
For the split reverse cycle aircons I used a central GlobalCache IP2IR infrared blaster, and then ran long wires with a concealed IR emmitter fitted inside the aircon head units. This works fine but the IR programming for air conditioners is painful. I wish there was an automation interface standard for them.
For the ducted aircon I had to integrate the zone controller using an arduino for digital IO, communicating back to the central server via RS232 serial (over cat5). I upgraded the fan to use a VFD (variable frequency drive) and this can be controlled directly over RS485 using MODBUS RTU.
-- Conclusion --
If I had my chance again I'd probably just run multiple cat5e or cat6 to every room
- 2 to 4 at floor level for computers and TV's
- 1 or 2 behind the light switches for potential CBUS or other wired lighting control systems. These would be wired to a seperate patch panel
- 1 or 2 behind a wall mounted sensor enclosure - this could then have both a temp/humidity sensor and IR emitter fitted. These would also be wired to a seperate patch panel
Ideally I wouldnt run any mains power to wall light switches - all of t

In my third house, I put in fibre everywhere for ATM and wasted a lot of money. Did I say I wasted a lot of money?
In my fourth house, I put in CAT6 everywhere for 1000BASE-T since it should also do 10GBASE-T. But my runs were longer than 55 meters.
In my fifth house, I said, #%!% it, and didn't wire anything. It became a ghost house where if I pick up my wireless phone, my Wi-Fi connection dropped, my Wi-Fi cameras went nuts, and my Wi-Fi controlled lights flipped randomly. It was great for Halloween.

Conduit, cameras and security (Score:3)
I like the idea of conduit for wiring because it allows you to add or replace cabling you otherwise wouldn't be able to, but I think you have to be smart about the structure of the conduit so that you have accessable, big junction boxes to enable long pulls or pulls between areas that aren't in a straight line.
One thing I'd like as an existing homeowner is video cameras and monitoring. I don't think I'll ever have them where I want them, though, because the wiring to corners of eaves and other locations is so onerous. In a new house I'd definitely want to plan for this because these are a lot harder to retrofit than wall locations.
The same is true for alarm wiring.

All he said was "my dream home" and "4000 sq ft", so it's not unreasonable to assume a single family home.
And yes, everything that consumes finite resources is everybody's business, that's why water and energy policies are so often in the news -- you can't separate water and energy from consumption, since whether it's food, lumber, or home automation equipment, everything needs water and energy to create. For that matter, you can hardly separate water and energy since the two are so intertwined.
Any individual can ignore the consequences of overuse, since it's true that one person really doesn't make any difference. But that doesn't mean that as a society that we should encourage it. The population is growing and, barring any catastrophes, will continue to do so for the foreseeable future - in 50 years there could be 100 - 300M more people living in the USA (depending on which population growth figures you believe) and it will be a lot harder to accommodate that growth if everyone lives in 4000 sq ft houses. Plus, as the world population grows and more and more people graduate to a 1st world lifestyle, energy (and other resource) demand will grow even faster than the population.

I propose we create a system that will regulate how society allocates limited resources to people. We could even set it up so that people who contribute more to society are given more allocations, in order to incentivize them to contribute to society instead of just consuming resources. We could even create a secondary market for allocations, so people could choose what interests them more - energy, housing space, water, location, etc. We could even set up the government to operate by just taking percentages of these allocations, and trading those allocations to accomplish things like building roads and parks.

Re:Insteon (Score:5, Informative)
I have exactly 42 addressable Insteon devices, plus some access points and some motion sensors that are not addressable. The reliability of all of them hovers about 90%. Note that Insteon retransmits up to 4 times if ACK is not seen. Only one device has 60% reliability, and that is probably due to wiring that leads to it. I also have one Insteon thermostat; it is so bad (crashes) that I cannot have it in the network.
The largest problem is when you walk into a room and press a button. Two events are generated at the same time, and they are competing for bandwidth. Oftentimes one of them is not delivered to the controller. Insteon is not that good at resolving collisions.
I have some Z-wave devices, since I'm developing their firmware (we have the license and the SDK.) Z-Wave is faster, and this means that probability of collision is lower. There is also spatial separation of segments of a larger network - RF reaches only some nodes, but not all of them. In power line based systems all nodes hear all other nodes because the injected signal is pretty loud. (Exception is RF connections of Insteon, but even then if several access points hear your motion sensor they may both retransmit.)
One obvious advantage of Insteon is cost - these are cheaper devices. But expect about 5% of them to fail on you. I have three devices that are dead now. Insteon also works in steel NEMA boxes; Z-Wave will require the antenna to be dragged out.
