I need a 240V switch that can be controlled via USB, also being able to measure the current flowing (or at least the presence/lack of some current) via USB. Linux compatible of course :)
Ideally this switch would have a dead mans reset too - my linux controller would need to send an 'on' signal every (say) 30 seconds or it would turn off automatically.
Any suggestions? I could probably build the 240V logic myself but aren't qualified and it would suck if something caught fire etc because I did something stupid :)
Actually even better would be something that communicates entirely over the 240V power eg X10, but would also need to be able to report back current usage (I think X10 is send-and-forget), and for the project I have in mind I'd also need to be able to report on a few switch states too via the 240V... That way I could have the controller somewhere else entirely. James
