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 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)?

If you go to this thread 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.
