Home Automation Idea
« on: April 03, 2013, 11:19:03 am »
Hi all,

please move if this is in the wrong section..

I am looking into a cheap option for control of the light in our home in perth australia. I found these power switches that are normally used in data centres. I guess the question is can i put Iec connectors on the end of the lights and plaug in this device legally?

I was going to get an electrician to do the work.

thanks Damien

Are you talking about the fixed (ceiling, etc) lights?

Why not use one of the proper devices from Clipsal, Dynalite, etc ?

Mainly due to the fact that this is only $190 us delivered and take simple http commands that can be delivered from a web server andriod setup that also will control xmbc.

Not to sure on the dynalite pricing but cbus is really expensive. I have looked at Z wave but at $88 a light slowy adds up in price.

IMHO its a very clever idea. I never knew these devices where that cheap. You'll need to watch the maximum load though. I don't know why it would be illegal to use a device like this. As long as there is no fire hazard you should be OK.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

For my particular use i will be installing a number of 4w led downlights and a few 10w led flood for outside so shouldnt come close to the 15A max input.

Yeah i cant see an issue i was hoping a sparky maybe a member of the forums :)

Especially since in a lot of newer installations they all just use sockets in the ceiling cavity anyway, you could just get IEC tails and fit them to the lights or tails with sockets on them so you could just plug the lights into the tails.

For the price and the format, these look very nice; I beleive i have seen IP-serial remotes for android, so you could just make a remote with buttons for serial commands that did stuff. would be nifty.

i'm no sparky, but i would imagine if all of the runs out to the lights where terminated in a patch panel with IEC sockets, and possibly the input run to the conventional breaker for lockout, i cannot see why there may be much of an issue, as then it would only be a case of you swapping around IEC 0.5m extension leads, with no lethal voltages present on exposed connectors,

though i would also imagine the feed ins would need to be in metal conduit until they enter the wall (if along the floor, otherwise may only need pvc) and the cabinet / rack would need to be bolted in place to prevent easy access to the mains terminations,

I just would have done the lazy thing, get a sparky to put a GPO in the ceiling, throw the box in the ceiling and plug the lights into the box, the box into the GPO and then run the ethernet to your patch panel.

I don't believe so, you can put whatever you want in your ceiling; it becomes a sparkys job as soon as it doesn't have a plug on it, downlights ect these days often have plugs on them, or you could add them and no one would be any the wiser.

I'll tell you, living in a region with no electrician licensing is both a blessing and a curse. Seeing you talk about dragging in a sparky for this kind of stuff makes me so happy I can do it all myself, but then I'm practically living in fear of a house fire all the time until I finish getting my house rewired because the guy who did it initially was a complete dunce...

I wish i could do it myself would be so much cheaper!!

So i spoke to a sparky and he didn't think there was any issue with the idea. I think i might get one and see how it goes.

Where I am at they have the "national electric code" and it's not hard to get access to a copy.

note: All the rules change when the voltage is under 50 volt.

You might look at the rules for your area for something like "In Wall Extension Wiring"
Like an extension cord, the rules prevent two sources being connected by the types of connectors.

Here most of the time, it's ok if you pull the wire and the sparky puts on the ends.

Ok I am a sparky and just having a quick look at this as for as i am concerned the first thing is this device certified for use in Australia
second the reg's deal with fixed wiring so is this fixed wiring ? the gray area i would say no if run with leads so plug device where you want
make up lead with iec plug at one end socket on the other and plug in you light etc  do not connect to any fixed house wiring not very elegant but what do you do i might look into this a bit more later

U.S.? Yep, sparky licensing (Do we even say "sparky" here? I seem to have acquired that word with no sense for where I first heard it. I like it, though) is regional in the U.S. New York State doesn't have it. Many counties and cities in NYS implement licensing, but the little one I'm in does not.

If you're in one of the regions within NYS that don't implement their own licensing, sort of. It's still "required" to be according to code, but they're not exactly sending the NEC police around ripping out people's outlets to check their work. Sadly, I've seen more work done poorly than not. It's amazing we don't have more house fires.

Some locations do the smart and easy thing and pass a rule saying just use national rule.
national rules are slow to change, but

then you run in to a local know it all that pushes requirement for something like cast iron pipe for sewers and a ban on plastic pipe for sewers.

For a lot of areas,   licensing is just a protection racket nothing else.

I currently have X10 devices although not installed I will eventually. They come from www.smarthome.com.au and they are reasonable in cost for Australia that is. So of the products will require installation but are minimal effort and in a couple of case do not require an electrician to go into the roof so should be cheaper. The only concern I have is main noise and whether there will be an affect on other equipment in the house.

Looks like they ha done away with X10 and gone with Z wave

Looking at sort of future proofing and i have heard that some solar systems cause trouble with the signal.

I also am changing over a bunch of lights so i need to get a sparky in anyway.

So if can i run extension cords through out the ceiling with out an electrician?

DOM,
The power line is a very noisy environment for communications. Most X10 devices do not supply feedback. With human feedback this may not be a big problem. If you want computer control to work correctly, you really need feedback. I have seen all kinds of things cause trouble with X10, the blender, the mixer, the motor starting. some light dimmers. While some X10 devices may supply feedback, a lot of the controllers do not use it.

Probably the best way is to get to a system that uses separate control wires. For lights you may want to look at
"DALI" http://en.wikipedia.org/wiki/Digital_Addressable_Lighting_Interface
"DMX" http://en.wikipedia.org/wiki/DMX_%28lighting%29

Have the central controller constantly "refresh" the state of all the modules and repeat a command several times in a few seconds on every state change.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

yeah i didn't think of everything else causing issues with the x10. Pretty sure there is a similar product that includes confirmation signals.

I am thinking of getting on of these as long as it meets aust specs ( value my insurance) and connecting it up to one light allowing for some testing then roll out through the house.

Does anyone know the answer to the previous question? If the cords have plugs can i lay them through the roof space?
