WoL always on, although when the device is off
### Backstory

One upon a time a can't wake up my device, although it was online

### Issue

Since the latest version and jump from version 4 to 5 i recognized, that the plugin is always on, although when the device is off.
If i reboot the Homebridge everything works fine for a while, but after a few days i can't wake up the device again. It is offline and the Plugin shows me online. If i click to switch off, it switches back on. Just a reboot helps me to run the plugin again correctly
