I can't get the built in light to work
- Tried using lower case letters in both sid and password,
- Tried using capital letters in both sid and password,
- Tried capital in sid but lower in password,
- Tried lower in sid and capital in password.

I've tried deleting the cachedAccessories file, creating a new Homebridge-config.

crypto.js:191
  this._handle.initiv(cipher, toBuf(key), toBuf(iv));
               ^

```
