I have since bought 3 more of these items as they are a great price very useful and seam reliable.
There is one improvement I could recommend for this device. This would be to locate a small switch on it that would flip the polarity of the input connector. This switch would then also function as a local control or override switch.
The attached diagram will help if you are interested in converting the "Normally ON" or "Normally OFF" pair of plugs to "Always ON" (but still switched and surge protected). Use at your own risk!
1. Uses Solid State Relay, which is silent.
2. Have a "pro" version that has 2 or 4 channels to control 4 independent outlets.
I am sure that there are some buyers out there who like to have an enhanced product like that, and the market is there.
I bought this High-power relay to replace a malfunctioning "smart" power strip for home theater application; the smart strip senses the increased current drawn by the receiver and switch on the power for the subwoofer/Bluray player/CD player, etc... to prevent leaving those accessories on all the time. Well, the smart strip worked OK for a year & half then no longer switch on. I didn't feel like spending another $28 or so for a similar design smart strip that might die on me again so I want to try this one.
I will use the 5V DC from the receiver's USB port to trigger this relay on thus powering all the accessories. To connect and control this relay I chopped off the end of a micro USB phone charger cable then connect the Red and Black wires to the relay's green connector - the USB end would plug into the receiver's USB port which energizes when the receiver is turned on.
Let's see if this thing lasts longer than 1.5 years.
It has two "Normally Off" outlets which will turn on when triggered, one "Normally On" outlet which will turn off when triggered, and one Always On outlet.
If you want it to power on more individual devices, you can pair it with a simple power splitter. It has a max current of 12A which put it at about 1440 Watts. As long as you don't try to exceed that you should be fine.
It's also surge protected.
It makes a "clack" sound when it's triggered, but there's also an indicator light to let you know that it's detecting a trigger signal.
This is an absolutely perfect fit for my use case.
- Quality Construction
- Simple Operation
- Absolutely huge trigger range
- none at all
In my case, it was simply 1) Connect a ground pin on the pi to the negative side of the terminal with a jumper wire, 2) connect a GPIO pin to the positive side of the terminal, and 3) plug the terminal into the relay. Then 4) set the GPIO mode to out for that pin, and run gpio write (pin number) 1 and 0 to turn the relay on and off. The whole process took less than 3 minutes to wire up on a breadboard and have up and running.
Compared to the other sensors and such i've worked with, this may be the absolute simplest-to-use peripheral I've used with my raspberry pi.

- I've put my TV on it.

Now when my computer turns on (one key stroke), everything is turning on, no need to fetch the remote control. :)
The 5VDC or 12VDC from you PC power supply will be enough to trigger the IOT relay. Enjoy.
So far so it's been reliable and is a great solution.
