Browse Forums General Discussion 1 Dec 10, 2012 9:28 am while doing the getting up thing this morning I was thinking about all the crapping around involving getting lights everywhere & thinking that in the factories where I work we're putting in Switch's that are capable of transmitting 17w down the Ethernet line (at distances up to 80m) so why arn't houses running all lighting off Ethernet based systems? so I jump online this morning... and low and behold! http://www.smartconnectedcommunities.or ... d-lighting So, I'm going to be running extra conduits (with curved bends and pull cables) from everywhere around the house to a central location in the roof, in this central location I'll setup a IP sealed cabinet, then as they get this stuff right I'll swap out the million transformers they want you to run for down lights, and all the other crap with essentially a whole heap of Ethernet lines. Anyone doing any of this? Experiences? anyone actually install it in their own home?

I don't recommend relying on high-draw devices all the time using PoE, but certainly it's useful if you want to have say a switch in each room that requires no power adapter - this is what we're doing in my new place. The thing to be careful of with PoE is that it means you need power supplied from the other end - this can often mean a beefy power supply which may need redundancy (or all your devices in your house go down). I'll be using a Cisco 2811 or 2821 for this - an Integrated Services Router that provides power to all phone handsets, some security cameras, some control panels, and switches. This also handles VoIP etc etc. The catch here is that the network module required to handle PoE on this many switchports needs quite some cooling and power.

Re: anyone running Smart home systems? 3Dec 10, 2012 12:25 pm what your doing with the ISR is exactly what I'm referring to, you can power just about everything small off it, I'd estimate that your power delivery from a HP or Cisco switch is going to be far more reliable & clean than the yum cha ten dollar converter bricks (not to mention the losses with each brick, bet the POE switch is far more efficient) I've always had problems using Cisco gear though as they seem to have gone out of their way to make your life harder than it should be that and many of the industry people with far more knowledge that I do complain about the hardware spec lacking. The switch's I've worked with have been entirely POE, so for $1k you get a 24 port 375w POE switch that you can log into a web interface and flip it on and off etc (we use this for security camera's at work) they definitely need some power but we've found that switch's running with half the ports active and drawing around 100w of POE run near cold (A HP V1910-24G), I can only assume that the switch's manage the power a whole lot better than your average power transmission, I also agree on the backup side of things, but the cool part of this is most switch's at this level have redundant power ports, so in theory you can port the switch to your Solar array ? While I'm sure Cisco can do it I have issues with the amount I know they're going to charge to do it! we need someone small in the game, someone who can offer the LED downlights that run straight off the 48v rather than just switching the existing power or running 48v to 12v converters etc Slooowwwwly getting a Manhatten 35 in Middleton Grange Re: anyone running Smart home systems? 4Dec 10, 2012 1:49 pm Networking hardware is designed for data systems, not lighting systems and electrical By all means control it via eth, but don't go running your lighting via a data device :/ There's a very good reason you put lighting on a different circuit to other electrical devices.
