Avi-on module broken

Third party integrations

Using HA v0.88.1 on a raspbery pi 3 running raspbian jessie on virtuaenv
Edit: Upgrade HA to latest version 0.103.0 and the problem persists

I tried both methods of control via username/password and directly providing device address. Also imported the python module from inside virtualenv and manually tried to instanciate an Avion object gives the same result.
Problem seems to be when connecting via bluepy/btle. HA gives the following message

A quick google search seems to be pointing to this issue which also references avi-on
