I'm looking for a ready made box that can be connected to ethernet and used to control a voltage supply (something like 0 to 24 volts) via a simple protocol. Does anyone know of anything like this? I found http://www.controlbyweb.com/ but their devices only act as relays (switching equipment on/off) rather than controlling the level.

Thanks for any suggestions.

What is your end goal here?  What are you going to attach to this ethernet-controlled-voltage?  How much current will it draw?

Also, I assume you're after DC rather than AC?

Sorry, I misunderstood the spec. It turns out I just need a dual-channel Ethernet relay that can connect two terminals to ground - no voltage or current required.

Any suggestions for an existing box that:
1. Doesn't cost a small fortune?
2. Is available in NZ (or reasonably quickly)?

Thanks.

If you go to this thread http://www.geekzone.co.nz/forums.asp?forumid=73&topicid=113569 and can persuade Hamish to share the details of how to program them, the WiFi bridge will probably do what you want for a very reasonable price.

Sounds like you're looking for something in the home automation field.

andrewNZ: Sounds like you're looking for something in the home automation field.

Probably, although the home automation units I've found so far are stupidly expensive. What would be ideal would be a hobbyist/DIY box.

I know the best way of doing this would be an Arduino or something like that, but we need this in a hurry.
