IP relay and LAN control

Don't worry - E-Bay isn't really a 4-letter word around here... There can be good deals to be found there, and there's nothing wrong with that! In fact, if you find something good, do share!

Is youtube banned here? I mean direct linking?

There are more movies, also in english from the same author.

Nothing is banned, you can link any site you want, as long as it's appropriate

I know I'm late to this discussion, but here are my ideas:

For software, you could use a free program called Premise and make a .net program that communicates with the Premise server (using minibroker dll). The .net program would map one of the keyboard keys to a Premise home object that would be mapped to a network device like a this that supports POE: http://www.globalcache.com/products/itach/ip2cc-pspecs/ You could also install your .net program on any computer where you want keyboard control, provided you provide some means to store the location of the Premise server along with the user name and pw.

Premise already has a native add-in for controlling global cache stuff so it wouldn't be too difficult. Premise also supports SSL so hopefully it will be secure enough...

I do not know the official specs, but I have one near Phoenix for about a year now including last summer. I mounted it in a water tight electrical gray PVC box on which I drilled a hole on one side to run the wiring conduit. I think it was a 4x4x2" container. It is mounted behind a post so it does not get direct sun exposure, but does get the 100+ degree ambient. I use it with a Vegitronix moisture, humidity and temperature measurements. The powerline ethernet and wallwart are also outside under a deck awning.

I have a single zone drip irrigation system there and this would be a good application for using a relay output of the WebControl. My problem is that the existing controller is not in a good location to do something like this so I probably will not ever take that step. With last years data I can see that there was not too much variation throughout the summer so a timed controller is good enough and then set it bak in the Fall.

I do not think their manual has the temperature specs so giving them a call is a good idea. Your 60 degree is outside the commercial electronics range which normally has a 55 degree max. It has no heat sink on the regulator, so you will want to use someting like 7 volts at the connector if you do not want to generate excessive heat to get the voltage down to 5 volts. Adding a little fan would likely also help.

You could also be a little more creative and cut out some of the air conditioner cold line insulation and mount the electronics on top of it. It will stay nice and cold. It is a shame to hog all that cold when there are better uses than just keeping people cool.

They sell two versions. The BRE is what I developed software. While both versions have support for internal logic, but new one has a better logic engine. Both have the same remote access and control capability via wired IP.

I think it is better just bypass the regulator totally by feeding regulatord 5V, that will make it cooler in operation. The MCU used on the board is a Microchip processor, which stated in Microchip site can operate from -45 to +85C. The TTL output buffer chip will depend on the load current. If driving a SSR or other IC input, it will not produce much heat at all. Just checked with manufacture, all their IC can work in free air at 85C.

My friend brought a new board with PLC firmware that added a /getall.cgi command helping host software getting all the status in one call instead of parsing the GUI.
