Hi,
I was wondering if there is some sort of compact and cheap plug in module that would provide power to devices, but would require a manual reset following a power outage?
This would solve a problem I am having with my setup:
1. I have an Onkyo receiver that will power on after a power outage no matter what its state was prior to the outage.
2. I use the rs232 port of the Onkyo to turn on other devices using a custom PC running the free Motorola Premise program.
Problem Details:
Due to the two rs232 fuctionality of the Onkyo receiver along with Premise, a user turns on a device automatically by hitting the source button on the front of the receiver... In my setup, if you hit DVD, all other players are sent a discrete Off command, the DVD player along with the projector receive a discrete On command. The problem is that the Onkyo sends the same ascii code for a given source over rs232 when it first comes on. If my receiver comes on after a power outage and I'm not at home, my projector could run a week!
Possible Solutions:
One software based solution would be to use a timer to ignore the source ascii code for x seconds after the power on command is received. This would ensure the components stay off (projector and DVD player), but the receiver would stay on!
A better solution would be a simple module that uses relays such that the receiver will never have power following an outage until a reset button is pressed manually. I believe this relay scheme is used extensively in an industrial setting for safety reasons (ie big push buttons). I'm hoping there is a much smaller option that can handle a 120v 15 amp load.

I could even have an email or text sent to my phone upon a power outage so I would know about it. This would also email me a summary after power is restored, ie how long the outage was, were the batteries drained etc...
