Is is important to turn on power supply before FlexRadio 6400?  I am turning on both remotely using WiFi sockets.  First I turn on the power supply and then the radio.  When shutting down I turn off the radio and wait a minute or so and then turn off the power supply.

I use a WiFi socket.  It connects to the WiFi in the house and I have an app. that allows me to turn it on and off through my iPad.

I use the same type socket to turn my Flex 6400 on and off, through a simple 12-volt relay.

My last one is 30 amp, 4-pole relay for automotive applications.  I bought it at an auto parts store for about $9.

Mike, just a quick note to publicly thank you. I have been wanting to tackle this project but a new year resolution I made to myself kept getting in the way. Your post was perfect timing. I bought the light switches from Amazon in a 4 pack deal. I found a relay in the parts bin that I removed from a circuit board from something, and an old wall wart that had the end clipped. My four switches work in this fashion:
1 = Computer
2 = Power supply which also turns on the Palstar HF-Auto tuner
3 = Flex 6700
4 = Palstar LA-1K amp

I did check the relay and I have no DC voltage on the contacts and the wall wart is only 6 volts. Even at 6 volts I think that is still above what Flex has stated as the max on the remote socket.

I do have some concern about the 10 amp max rating of the switches running the amp but I rarely run it at full rated output. I also do not like the power supply turning on the tuner but the tuner requires very little power. I thought about using the power supply to also turn on the flex but that really bothered me so I went the relay route. Your drawing above made things really simple.

Below is a link to the Amazon item. I just did a quick search and found these although others are available. I choose these due to the manufacturers name being on them and for the fact that I can use my Android phone to control all of them. Set up was a breeze.

Thanks Mike!!!

All the posts in this thread have been great in helping to understand how to set up this remote switching setup via WiFi. Can anyone post a link, part # and details on the Relay(s) you are using to switch the RCA plug to ground for the Remote Turn on for the 6xxx ?

Why use a relay. Short the remote terminal and simply turn the PS on/off with a single WiFi outlet! Works fine with my 6700.
