![]() ![]() sudo chmod +x /home/pi/wol.shĪdd this to the bottom sh /home/pi/wol. Also, make sure it is properly set up for WoL. All you need to know is the mac address of your target computer. This is for tcpdump which needs elevated access to listen to eth0 and etherwake. To wake a computer over your LAN you need to create and send a so called magic packet. Then put it in the sudo crontab to launch as root. I named the file wol.sh and made it executable. If the server is awake then it wont be listening for an arp request but send a few pings every now and then to make sure it is still awake. The primary idea is that it is run from my raspberry-pi which will wake the server if it notices a single arp request for the server. VarPing=`ping -s 1 -c 2 $target > /dev/null echo $?` PingInterval=60 #time interval, in seconds, between checks that the server is still awake. The wake script is as follows: nano ~/wol.sh Also on the server Wake On Lan needs to be enabled as mentioned in the other posts. Both are not installed by default on rasbian. The raspberry-pi dependencies are etherwake and tcpdump. I will show you how to create Home Assistant Wake on Lan (WoL) switch to turn. The final solution I found for myself was writing a little bash script. Basically the same as Android users, open Tumblr on your browser and click. I enabled on tv developer options and enabled wake on wan and wake on lan. I have alexa echo dot set up via hacs integration - alexa media player. I have a raspberry pi so I used it because it is low power and I don't mind keeping it on all the time, of course it could be run from any linux machine. I set up my tv via android tv integration and chromecast integration. I decided I wanted a solution to wake my media server automatically when accessed that wasn't dependent on dd-wrt. Obviously, you have to wait for a while after you sent the WOL packet, as your system needs to de-hibernate and it could take a few. Im not shure about rest of the code, but you should use String mac mactext.getText().toString() instead of String mac mactext. Server doesn't need more setting than the suitable power management configuration to get the system down after an hour of inactivity (it could be done from System > Administration > Power management). Check it! In my case, it is called "Power on by Ring on Lan". The most of modern MBs provide this feature, but is disabled by default. Your motherboard needs to be listening on LAN port when is powered off.Your router has to bypass the magic packet (as the WOL packet is called) to your server, so you need to do the port forwarding.There are a lot of tutorials about it, but mainly you need to set up the following: So, as many have pointed, the answe is WOL (Wake On Lan). Further than sleep mode, what you're looking for is hibernate, as you want to save your state in your harddisk and shutdown completely the server.
