Problems ssh to windows only from homebridge terminal
### Backstory

I have followed steps from the wiki for the shutdown command and everything works apart from when I try run the command from the homebridge terminal it doesnt work but when I run it from normal terminal then it works fine

### Issue

My homebridge folder thing is in the home folder not sure why, I cant create folders in the root drive so yeah. When I run it in homebridge terminal this shows up, I went and check the permissions tho and it says that everyone can read and write. why is it not working? Obviously if I type the password it works but it should be keyless ssh so I can just flip the switch on my iphone.

Load key "/home/homebridge/id_rsa": Permission denied

When I follow these steps:

2. Run `homebridge`
3. Let it run for a couple of minutes
4. Try to turn a device on or off using the plugin
5. Wait one minute
