Thank you Mike for sharing the knowleage! This will be very useful.

Great idea for a SONOFF. If you check your PSU wiring, you may find a +5V and 0V that you could use instead of an external wall wart and USB cable.

Thanks Mike !! for this help

A couple years ago I bought a few of these wifi switches. I used one for the Garage Door Opener one for the PC and kept one for a spare. I added Voice activation with Amazon Dots. On the PC, I mod-ed the PC Power switch cable so the PC can be powered up with either it's Case switch or App or Voice control. A couple months later the Garage door had three un-commanded openings in a couple week period, so the spare I bought was used to replace it's defective WiFi switch. The PC is located in a hard to get spot. Voice command is great. I changed the Amazon Dot activation word from Alexa to Commuter. So I just say Computer on and the PC will turn on or off depending it's state at the time. The Garage door has worked properly now for a couple years since replacing the Bad switch.

Thank you for the idea. I prefer several pairs to trigger an action for separated devices. :) Will check :)

Im just doing this to the render/nas station i just built, thanks mike.

I love it. Love it love it.

Thanks for an interesting video. Just a thought, When a PC "Hangs properly" You have to hold the "Power button" depressed for 4 seconds in order to turn it off. So maybe using the "Latch mode" of the "relay" would be more "suitable", since "holding the power button pressed" won't do anything bad when it isn't needed, BUT it can solve problems that "clicking the Power button" will not resolve.. Best regards

Hi Mike. Wow, thanks for this video. I was down a rabbit hole of an Arduino project to accomplish the same thing! One question however - how about operating this device from something other than the mobile application. Did you ever discover what protocol is used to communicate with the device itself?

Thanks for information, this was helpful. I want to know How safe is to use it for an extended period of time will cause electric damage to my PC ?

Thanks for the video it was very helpful. I am having problems. I bought the device, wired it up, no connection issues but it won’t power on my pc.

Thanks Mike!! Where can I buy the hardware? I dont know how to search for it...

Thanks Mike for the quick reply, when you say set up a VPN are you referring to the router or computer?

Just buy the same wifi switch with enclosure, I did this also and it works fine

first many thanks to the video and the good explanation. but I have one question, Is it possible to keep the pc button connected and connect the relais in parallel so that it will be possible to use both the pc button and the app to power on the pc? thanks.

Hi Mike. I appreciate the video it appears this is exactly what I need. I connected it at home and it worked perfectly, however when I brought it to my office I could not get the device to work. No matter how many times I tried in compatible mode it would connect without internet. Everything is connected but no WiFi. My WiFi is working and I am using 2.4ghz. Any suggestions as how to correct this?

I would like to remotely toggle on/off a surveillance microphone that plugs into an RCA audio jack in the back of the surveillance DVR. There is USB power available on the back of the DVR as well. Do you think this device and app would work for that?

Can you set it as a momentary mode like the power button on a pc ?

Do you know if there's an easy way to make this work together with the case power button? I made the easy setup but then I (obviously) lost the case power button functionality

Does this work if you are connected to public network such as university networks and try to remotely open your pc? ( also if ISP does not allow static ip / dynamic DNS for ports. )

Do you have to be connected to the network? Or can you access this from anywhere on cellular data ?

You mentioned connecting this device to your Guest network. Is there any other way that I can increase the security?

Just flash Tasmota to this device for pure local access then use something like Home Assistant for your unified control of devices.

Hi Mike, I checked my PC and realized my power switch has 4 wires going to be connected to the motherboard (4 pins connection). do you think 2 pin connection would still work to replace 4 pin connection for a remote start?

Can this be powered by the pins on an internal usb header if so which pins

Hi Mike , is it possible to reset it ? I bought one and I would like to test first on my pc before I use it on Another pc at work .

How do you adjust the time that it “shorts the contacts”?

Do you know how much electricity goes true when you press the button on the app? like how much volt goes true that thing, i want to know so i dont frie someting ;)

Done this with an ESP-01-S

I have the 2 channel board and am trying to convert my wired adjustable bedframe to wireless with it. The remote has 4 wires, head up, head down, ground, and vdd. How would I wire that up into the board?

I can't even get the darn controller to pair with the app. I made a guest network that's a 2.4 band and I still can't find the device

Im confused you said turn on and off anywhere in the world you connect the via AP mode.

Don’t you need to be connected to your local network in order to gain access?

need video on remote login and use after remote start.

can this remote start work outside the network?

I don't know why no one has asked, but we would love to know if it's possible to do this for a laptop.

Can't help in disaster preparedness if power is out. 😂😂😂

ewwww.... almost a great video, until the end about turning the PC off. need to show how to go into power setting in the PC and change what pressing the power button does when PC is in the on state. not all folks know this and not all PC's are set to turn off by default. other then that, this is a really good video.

I tried Ewelink and found it to be very unreliable and now use Tuya that is much better
