After years I've been able to do some updates to fix few warnings and solve a couple of issues.
Unluckily I would not be able to add new features since I'm not an expert programmer and so it will took me a lot of time to do things. Time tha t I don't have..
I'll try only to keep it working through HA updates that sometimes can have breaking changes.
You can always make pull request and I'll merge them! If you do please ensure that the change works and doesn't break anything else :)
