Is your feature request related to a problem? Please describe.

It's a great project! Thanks for your time making it! However, this project deserves a bit more time to fix issues. Would it be possible to add more maintainers that can merge pull requests?

Describe the solution you'd like

There are at least 2 forks ahead of the main from @daniele-athome and @Benjamin-299. Perhaps you can add either of them to keep an eye on it?

Describe alternatives you've considered

I'm a Python developer myself, but haven't worked with HA add-ons ever. But for me, such an integration is crucial, and it's replacing my hacks with input booleans and other stuff. I'm not yet ready to pick it up but if others refuse I can become a maintainer too

Additional context

In the current implementation, there's a bug that affects changing sensors' parameters (#78 is fixing it)
