Re: Distant powering using device local control (difficult to describe!)

["noughtomate" <balraj_jassal@xxxxxxxxxxx>]

Thanks for the ideas.

Ok, I'll own up :
- Device A : Synology DS-101g+ NAS server
- Device B : Netgear WiFi access point
- Device C : Belkin WiFi bridge to Ethernet


So, on pressing the NAS local power up, I want everything else to
power up.


I've pretty much limited my world to X10 at the moment so I have no
idea about Wall Warts, relays and current sensors.  Are there any
dumbo-newcomer websites ?

Cheers
