Finally realized remote boot, Raspberry Pi YYDS [Copy link]

 

 

The desktop computer is difficult to move around, and the laptop's performance is not enough.

Later I thought, wouldn't it be better to connect the Raspberry Pi to a GPIO, connect a relay, and then connect it to the mainboard to turn it on instead of the switch?

I did it right away and bought a dual-circuit optocoupler relay for a few dollars on Taobao.

Dual-path is one for booting and one for restarting.

Software Configuration:

1. Intranet penetration, basically you can control Pi arbitrarily by connecting to SSH

2. Write a GPIO script.

Hardware configuration, find the two pins of the motherboard power button. Connect them with a relay, give a signal here, and short-circuit the other side to turn on.

Is it possible to remotely boot the computer via a network cable? I remember that Sunflower needs to configure the BIOS.

Yes, you have to turn on network wake-up in the BIOS. It can be done without Sunflower, or if there is DDNS in the router.

How is it handled in BIOS? What is the communication protocol? Can you tell me? Thank you

After [turning on network wake-up in BIOS], I can actually boot the computer remotely using the Raspberry Pi.

No need for Raspberry Pi, a WEB page will do.

The following address is generally used for network wake-up.

https://www.depicus.com/wake-on-lan/woli

MAC address:
DDNS address: (set by the router)
Subnet mask: 255.255.255.255 (just select the default one, or it can be the same as the local machine)
Wake-up port: xxxx (the wake-up port set by the router)

Finally, click WAKE UP

Doesn’t network wake-up still require the network to be turned on?

The sleep wake-up and network wake-up are all powered on.

Does it mean the computer is actually turned on?

It can also be powered off, but the LAN port needs to be opened to monitor the fixed IP address and the network card needs to support it~ What does my old computer support?

I see. That’s not good, and it wastes electricity.

8266 is fine, but PI is a bit expensive. Just use the internal 3.3V or 5V to reduce the 3.3V power supply.

吾妻思萌

8266 should be enough. Using PI is a bit expensive. Just use the built-in 3.3V or 5V to reduce the 3.3V power supply

I use my PI with joplin and pihole to start the machine. It's not very comfortable~

I bought a Raspberry Pi 4B 2G version, but unfortunately I was so busy that it was covered in dust after I bought it. And the price was reduced by more than half later.

esp8266 connects to wifi, 10 yuan to get it done, Raspberry Pi???

8266 is OK, but esp32-c3 c2 is not much more expensive. esp32-c3 can use Bluetooth to connect to the network

It's not much more expensive, but it's several times more expensive. In addition, Bluetooth network configuration is not very meaningful. It's not that ESP32 is bad, it's just like Raspberry Pi, which wastes performance. 8266 is enough and simple enough

Ah, my PI is not only used for booting. That would be too extravagant. I have configured a lot of PI, and the intranet penetrates joplin pihole. I just use the gpio port to boot.

The network relay made of special eps8266 seems to cost only a few dollars. This Raspberry Pi is a bit extravagant.
