Wireless smart switch PTX_BT1_QMIMB not detected

[mrbutcher93]

I wanted to connect a Xiaomi PTX Mini Smart Switch with HA but unfortunately it isn't detected.

I think the main difference between my switch and the already implemented switch of #74 is, that the model name is slightly different (PTX_BT1_QMIMB vs. PTX_YK1_QMIMB).

Is it possible to add this switch to the list of devices and to the parser?

Thank you!
