I have a purchased a Xiaomi Mijia 3 Gang Wall Smart Switch (WIFI Version) - PTX Switch. However, I have not been able to find any information about adding this to HA.
After some research, I found that there is a library (itpansic/python-miio) that controls this swtich. https://github.com/itpansic/python-miio/blob/4717a176d3dd2dbb4fd28de1eb445f74adf574ec/miio/ptxswitch.py
Can anyone point me in the right direction on adding this switch to HA.
