Need Help and Advice, Python 3.6.4 and Broadlink

My hardware - RP3, HA 0.63.1 (Hassbian and Raspbian), Python 3.5.4, Broadlink Devices.

I try to upgrade/install Python 3.6.4 due to the soon of breaking change for python support in HA.

The upgrade was successfully to 3.6.4. However, Once restart and load HA, I lost all my broadlink switches and whatever regarding with broadlink, did not show up on frontend with no error.

Please help and advice.
