Sorry for the very late reply @danieleparazza , I don't check on github as much as Homeassistant.
I have implemented both yours and @gyuris fixes into the latest version. I appreciate you both for doing the hard parts for me!

As for any other fixes feel free to keep making suggestions and/or figuring it out and allowing me to implement your code into future releases!
