The new version adds support for Wake-on-LAN (WoL) over Wi-Fi using the Magic Packet technique.
Note that WoL requires the “Fast TV Start” setting to be turned off.
In my experience, Roku’s SSDP-based device discovery on local networks can be unreliable. The “Fast TV Start” feature is intended to keep the device in a low-power standby mode, allowing it to respond to SSDP multicast requests. However, over time, the device may enter a deeper sleep state in which it no longer responds to SSDP.
On the upside, disabling “Fast TV Start” can also help reduce power consumption and lower your electricity bill.
To enable WoL, update the IPAddress and MACAddress fields in the settings.ini file to match your device.
You can find these values using your Roku physical remote:
'* To read IP & MAC addr. : Home > Settings > Network > About
'* Turn OFF 'Fast TV Start': Home > Settings > System > Power
