ssh keeps asking for passphrase which gives HWOL-4001 when switch is used via homekit

[abhiiously]

Backstory

I followed this tutorial to get ssh working on homebridge-wol on Unraid, albeit the only way I can get it to put my computer to sleep is to have ssh-keygen create a key without a passphrase which I know is unsafe.

Issue

I keep getting "Enter passphrase for key '/homebridge/id_rsa': " when I manually run the ssh command via homebridge terminal but when I run the ssh command via homekit on my phone I get this error in the logs

"HWOL-4001 An error occurred while trying to shut down the device. This is most likely not an issue with homebridge-wol itself. For more information see https://github.com/AlexGustafsson/homebridge-wol/wiki/Frequently-Asked-Questions#hwol-4001"

Environment

- os and os version: Unraid 6.12.0-rc1
- node version: v18.13.0
- homebridge version: 1.6.0
- homebridge-wol version: 5.0.2

Logs

When I follow these steps:
1. Make sure `logLevel` is set to `Debug` on all `NetworkDevice` accessories
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
6. Repeat step 4

I get the following log:

When you generated the key, you likely entered a non-empty passphrase. This passphrase encrypts the key and will require it to be entered every time the key is used. You'll have to generate a new key-pair, this time without entering a password.
