[enhancement]: Possibility to only add sensor and switches
### Describe the solution you'd like

Hi,

I have both the Eufy Indoor 2k and the Eufy Pan Tilt 2k, both directly Homekit compatible.
As the native homekit capability does not expose ON/OFF switches for Power ON/OFF and Motion Detection ON/OFF, is it possible to have the Homebridge Eufy Plugin expose only these switches, disabling the cameras themeselves (which will be instead added to Homekit natively)?
Thanks!
