When I run the latest git head on KP125M:

No host name given, trying discovery..
Discovering devices on 255.255.255.255 for 3 seconds
Found 0 devices
Found 1 devices that failed to authenticate
Tapo plug requires authentication.

Is there a way to provision from python-kasa like the previous devices? Is there a default username/password or some new protocol that must be reverse engineered (maybe bluetooth)?
