## Questions & Answers

**Q: Want to use this along with a wifi smart plug to send a pulse to open/close the garage door. good application?  wall->smartplug->usb->dzselec->garage**
A: I used this product to automatically [open]/[close] my garage. 
1. Jumped the [trig] and [-] 
2. Solder [COM] and [NO] to the garage door opener button nodes
3. Set an automation routine on HomeKit or the WiFi smart-plug app to turn off the plug whenever the plug turns on

I am using the same method on my fireplace, without step (3), because I want the fireplace to stay on/off as desired. However, for the garage, I only want a short pulse to mimic pressing the garage button. So the automation turns the plug off whenever it detects the plug turning on.

Hope this is helpful.

**Q: Will the relay trigger as it is getting powered on?**
A: Yes.

**Q: if i short the push button switch will it trigger the relay upon applying usb power?**
A: Yes, if you short the trigger button, upon power-up, the circuit closes as you had hoped. 
Unfortunately, the circuit never opens (it stays 'on' as long as the trigger switch is closed, and never times-out.)

**Q: I am looking for a way to turn off the power from a 5 volt usb connection between 10 and 20 seconds after recieving power.  Will this do that?**
A: Yes. The usb on it is the 5v power in to the unit or power by the trigger posts.

### ⭐⭐⭐⭐⭐ Alexa, turn the fireplace on!
*by D***A on January 5, 2020*

After seeing that video in youtube, I had to make my fireplace smart too, well, semi-smart. This is the first time doing something like this and thanks to this little unit, everything worked. I don’t know much about the unit itself or can criticize its build and quality as in comparison as Simone who is always tinkering and building stuff, but for a first time user, it was pretty easy to set up. I’m happy and I’ll be seeing what other things I can make.

### ⭐⭐⭐⭐⭐ Raspberry Pi On/Off Switch or How to Turn On/Off Raspberry Pi via TV USB Port
*by F***D on August 26, 2019*

After searching for weeks for a simple and easy way to turn On/Off a Raspberry Pi via a TV and not finding a good solution, I found a simple clean easy inexpensive non-intrusive way via a $8.00 relay switch. If you can do simple wire splicing and know very basic wiring you can do this. Many TV’s/monitors have a USB port so this will work, and as long as when the TV/monitor is turned off and the USB port turns off its 5V USB power, this WILL work.I can confirm this works on a Hisense 65” 4K TV. When the TV is turned off, after 10-15 min the TV’s USB port turns off also. Other TV’s/monitors may do it immediately or take longer. On some TV’s you may have to go into the power settings or the USB setting and set the port to turn off when the TV is powered off.Preface: I have all my movies on a Western Digital 4TB portable hard drive that is connected to a Raspberry Pi 4B via USB 3.0, any version of a Pi would work actually. The Pi's video out goes to the TV's HDMI in. I am using LebreELEC and only have Kodi installed and loading up. Turning Kodi off is easy via the Kodi ‘s O/S, but the issue was that the Pi can’t be turned back on although power remains plugged in? To me this is useless as you can’t turn it back on! The biggest grip is that although it’s being powered, you can’t turn it back on so being powered has no real purpose (except the clock) other than wasting power even though it's very low and people say just leave it on. I also prefer to have it completely off as I don't care about the clock. The popular method everyone seems to use is to plug/unplug it or put a switch on the power USB cable which causes the time to be lost also so apparently many are accepting of this method.I found many other ways how to make the Pi be able to be turned On/Off; A manual On/Off switch on the power supply, a remote controlled powered On/Off switch on the power outlet, plug/unplug the power supply (the lamest), add on boards, IR diodes, add on boards that you have to install software or some add on boards to the GPO which take up space inside the Pi case which is already very limited. I rather leave all that open and available for other things as inside the case there is not a lot of room. I wanted no additional remotes, or deal with software or drilling the case (I have a FLIRC case) for IR’s or have any wires coming out the case. This method also does not interfere with the board itself, gives the box a clan appearance, does not need to use any additional power off the board or cause heat or amp loading issues and is very easy to do.So cutting the power gave me an idea to use the TV's 5V USB port as a trigger/power supply. Someone may ask why not run the hard drive directly through the TV? I can, but the media center the TV has built in is awful, a far cry from being able to manage anything or be useful as a media center, no artwork, or movie info being Roku. I can run the Pi off the TV USB port, but only by itself as the TV’s USB port does not have enough amps to drive both devices at once, just not enough amps.The solution was this relay switch: DZS Elec 5V-30V I channel Wilde Voltage Adjustable Relay SwitchSetup:1. All that is needed to be modified on the relay switch itself is to remove/unsolder the momentary button trigger and solder a wire across the switch to have a continuous closed contact across the switch. This will keep the relay switch On as long as there is power via the 5V input of the Micro USB 5V input.2. Connect a USB cable from the switch's Micro USB input 5V to the TV's USB port.3. The third part is to take the power cable you are using to power your Pi and tap or cut it to get to one line, either Red or Black. Tapping is best so you can leave all the other wires intact as they will not be used. You only need to tap or cut/use ONE line, either the Red or Black, but not both! All other wires may be left alone or taped off. Take ONE of the cut lines (ie: Red), and connect one side of that cut line to the COM (Public COM) terminal on the relay switch terminal and the OTHER side of that cut Red wire to the NO (Normally Open NO) terminal. If you cut the Red, do not cut the Black wire, leave the back wire alone as all the other wires in the power cable as they are not to be used. If you look at the diagram, you would simply take both ends of the ONE cut wire’s two ends (Red for example) and connect one side of the cut wire to the terminal named Public COM and the other cut side of the wire to the Normally Open NO terminal.Note: You will NOT use the Normally Closed terminal (NC). You do not need to worry about the relay time setting of 0~24 either as it will be bypassed due to closing of the button trigger switch. You also Do Not need to connect anything else to power the relay ie: trigger (TRIG) low level trigger or the terminals labeled Input + or Input - as they are not used when you connect a Micro SUB 5V input cable as they are just an alternative power input.Running/Using: Plug the power cable into the power supply and the Pi itself that was powering the Pi (on both ends) and connect the relay switch's 5V USB input power supply to the TV's USB port. When you turn on the TV, the USB port of the TV will energize the relay switch and power the Pi via the Micro USB input 5V. The light on the relay will turn on and stay on. This should load up or whatever you are using as an O/S, LibreELEC/Kodi in my case.After you are done for the day/night and ready to power off Kodi, use the O/S to power off, wait for the TV to show there is no signal on your input (whatever port you are using as an input) and then when you turn off the TV, it will turn off the TV's USB port removing power to the relay switch which will power off the Pi.I hope this helps someone who is looking for a simple inexpensive reliable solid way to turn on and off their Pi. As I mentioned, I can confirm this works on a Hisense 65” 4K TV. When the TV is turned off, after 10-15 min the TV’s USB port turns off also. Other TV’s/monitors may do it immediately or take longer. On some TV’s you may have to go into the power settings or the USB setting and set the port to turn off when the TV is powered off.Enjoy!
