[Bug]: configuration never saves, and I cant manage bridge settings
### What happened?

After installing the plugin, and logging in, clicking to save the configuration settings doesn't work. Even if I change a setting for a device, back out of the window to change another device's settings, the change reverts back. Because I cant save any configuration settings, I also cant make the plugin a child bridge and sync my devices with homekit, I am instead prompted with "You need to configure this plugin before you can manage its bridge settings."
