That depends on how it is presented. *Any* alteration that looks amateurish/DIYish will detract from the value. This applies to geeky wiring, lean-to sunrooms, DIY carports/sheds, whatever. The advantage of getting the sparky to install it when the house is being built is that it will look like it belongs there and not tacked on as an afterthought. It also depends on how it is marketed. When you describe the features of a house you are selling, don't use terms that make non-geeks' eyes glaze over. Instead market it in terms of useful things you can do, eg turn on heaters half an hour before you get up. The simplest form of automation is a bunch of timers in the 2nd switchboard (you can get DIN mounted timers the width of 2 MCBs that are easy to set). The set-up I outlined in my previous email can start with something as simple as timers, and be expanded to relays controlled by computer, or the relay outputs on a security alarm, or anything you like. Note on safety: Most DIN mounted relays provide 400V insulation between the extra-low-voltage coils and the mains terminals, so it is safe to connect the outputs of any Arduino-type device to the relay coils. Just make sure any wires from your device going into the switchboard are rated for mains voltage, even though you are using extra-low-voltage (eg double insulated conduit wire). Yuri
Re: Home Automation Dealers in Chch?
Hi Yuri, You missed another important advantage of having the automation gear in a separate switchboard.. When you come to sell the house, if you do, you can rip it all out and get a sparky to put standard bus-bars into the automation cabinet to take it back to a normal house. Home automation systems are not attractive to home buyers unless they are geeks, and lets face it, we're a minority. Even having comprehensive structured cabling in a house can be seen as a negative by realestate agents and a fair percentage of 'Average' buyers. Cheers, Me.

For each power socket that you want to control, get Sparky to run a four-core[2] (3C+E) from the power socket to the control switchboard. The controlled power sockets can have an extra switch[3] to select between manual and auto, hence the extra cores to carry the "always on" (manual) feed and the "controlled" (auto) feed. The advantage of the above set-up is that if you automation system fails, everything has manual override wired in so lights and controlled power sockets can operate as normal lights and power sockets. Also, you can rip out whatever is in the control switchboard and replace it with something else. Relays can have 12V coils that are controlled by your linux box, with the proper isolation if required. Yuri [1] Three core has the same number of conductors as twin & earth, but the colours are different. 3C has red/white/blue while T&E has red/black/green. The reason this matters is that the green can't be used for anything other than protective earth. [2] 3C+Earth has red/white/blue/green. Blue & Green can be used for neutral & earth, while red and white can be used for "Always On" and "Controlled" feeds. [3] eg PDL 691X is a socket outlet with room for an extra switch.

The thing about having Arduinos/controllers around the place is that you can do local processing at the same time as remote. For example, switch pushed = turn on light and/or notify server. You can be completely self contained, completely reliant on the server, or a bit of both. This approach lends itself to progressive enhancement without breaking normal expected functionality. At this stage it's very much hacked up bits and pieces, we recently shifted so amongst that and others things I haven't had a lot of time to do anything with it.

Re: Home Automation Dealers in Chch?
This approach interests me. I gather then that you run the Arduinos locally in each room/area with sensors attached to these and then use Zigbee and/or ethernet to connect the Arduinos back to your Linux server. What software are you running on the Linux server? For that matter, what software are you running on the Arduinos? :-) Running wires etc is all old hat. I had not thought about electrically isolating various areas and to be honest, I'm not even sure what that means. To do true isolation I would need to run 1:1 transformers or equivalent devices. I'm sure the comments here do not espouse that even if that would truly isolate areas from each other. Unfortunately, WAF needs to be factored in. She's not really into tinkering as much as I. :-) And I to no longer have as much free time for this as I used to. :-( I can't see why I can't run a commercial protocol and/or my own protocols alongside each other. It all appears to be Ethernet-based these days.

Secondly, do you ultimately want to possibly on sell your property. If the answer is to this question is yes, then stop now! With thanks to the other contributors, I;ll suggest the following; How far through with the build are you. just planning, builder, sub-contractors and architect selected? Have any of the people you are planning on utilising had any experience with "building control" systems? Ensure that the electrician you select is open to your input and not completed close minded. I trust you understand that anything you try to implement that deviates from a normal building contract will add to your costs. From the previous posters, they have given some good advice including; Install plenty of Cat6 to everywhere. (Should all be dual runs but the only recommendation for Cat 6 would be to have it professional terminated and not by your electrician. Get it tested properly at time of install.) Put in draw wires for future use. I'd agree with this only in partially filled cable conduits, dragging in additional cables after the fact mostly causes more problems than it solves. Run some 100 mm conduit to every building on the property. If this is done properly, ensure easy access to this infrastructure where it exits the building, to allow expansion of additional items. Remember that mains voltage cables and extra low voltage cables need to be segregated. See note above about Electrician. And plenty of power points and power capacity. Actually power capacity affects power points so be careful with your planning, I speak from experience as I discovered after the fact that my mains cable connection to my house was not 16 millimetre squared as I had 'presumed" but the imperial equivalent to ten millimetre squared. A separate circuit for each room is handy too. This is a given as the purpose of any automation must be the control of electrical loads. ie (loud stereos, televisions, and hair straighteners.) Electrically isolate the kitchen/laundry/AC/heatpump/HWC/bathroom from all the other rooms. Again this is the best planning but you need to ensure your electrician understands why and provides you with real reasons as to why it's not a good idea. I have some war stories about real world situations where the electrician made changes to a professional lighting design because it had too many lights and would use a lot of cable. Documentation, documentation. This idea is pretty good to. And photograph all the rooms to see where the cable runs are, before putting up the gib boards. Keep a printout of these photos handy whenever you call in a builder/workman for anything in the future. Did I say lots of documentation. There was also a comment raised about the size of your switchboard. Again, you have plenty of design options and decisions to make here and the working relationship you have with your electrical contractor will make or break the entire project. As the electrician has a legal (and moral) responsibility for the installation the design and fabrication of the switchboard to easily allow for the purpose of 'automation' (control) will require his/her buy in to your ideas. Shout out if you'd like any further discussion. If so we could take it off list and on down to a drinking establishment. Andrew

All extremely good advice! Every single point of it. Make sure your switchboard is big enough, I suspect you'll find a 30-way too small (I do). Kick the electrician(s) early, otherwise you get el-cheapo. Keep in mind that the conduits for data cables must be different to the conduits for power cables. Only solution is to double up. There are 4-way wall outlets available from PDL which fit a standard flushbox and the space of a double outlet. Easy way to get more outlets in a tidy manner. Personally I'd make sure to be able to run everything I want to run without any wireless. For a lot of home automation you'll need actual wires too. Treat wireless as optional, but don't depend on it. You can always go wireless, but not the other way round.

Re: Home Automation Dealers in Chch?
Ha ha. Good luck. X10 is not bad, but it has its problems, mostly that you cannot query the state of a node. I am also not sure as to its availability here. It was very cheap in the US, but of course, only suited to the US power supply. I keep toying with the idea of Home Automation but there are two things that stop me: 1) The Man is keeping me down with his legislation preventing me from doing my own home electrical work. (and yes, I know what I am legally permitted to do, but it's not sufficient). 2) There is no hardware to be had in NZ (apart from the expensive systems from Clipsal et. al.) So, my last idea involved the Arlec remote controlled outlet kit that I got in Bunnings for $30. I have mentioned it on-list before, but basically it comprises three plug-in modules with an electrical socket (much like a plug-in timer) and a handheld remote with 6 buttons in three groups of two. Each pair of buttons turns the corresponding module on or off. Because it is wireless, it works all around the house- no need for line-of-sight (cf. IR). Anyway, my plan was to dismantle the outlet modules, install a PIC, and hard-code the unit address (so I can have more than three) and hack the transmitter so it can be controlled by a PC. It still lacks the important function of querying the device to ascertain its state however. Perhaps what you really want is an ethernet enabled mains switch. After all, you do have Cat5e everywhere in your house, don't you? This will allow two-way communication to the node, which can turn outlets on or off, and report their state. It could have a new protocol using UDP for raw control/query, and an embedded web server in the node for casual interrogation. Another alternative is the Dallas one-wire bus. There are 'switch' nodes that you could connect (via optoisolators, natch) to a mains relay (or modified Arlec doodad). This is simpler than ethernet, with the added advantage that you don't need a local power supply (nodes are powered by the bus). The PC interface is easy to build, and you string the sensors off a multi-drop twisted pair (Cat5e is great for this). There are also several home automation projects on the Intarweb- but no one stands out as the ideal.
