Pulseway supports Wake on LAN and Wake on WAN over Internet.
The mobile application will send a magic packet in LAN while on WiFi.
As well, our cloud servers will send the same magic packet to the public IP address on UDP 9 (you can change the port number and assign a different port number for each computer using the Pulseway app installed on your PC, go to System->Wake on WAN over Internet, default is 9).
Please make sure that the router forwards those packets in the LAN and that the PC supports Wake on LAN (check BIOS and network interface settings).
The only limitation at the moment using Wake on WAN over Internet occurs when our cloud servers have the last public IP used by your computer and your public IP changes. The magic packet will be sent to the last known public IP and will fail to wake the computer. We are planning to solve this problem in the future using a different method.
