I didn't make the initial mysensors implementation in home assistant that only supported sensors, but I made the refactor that laid the groundwork for multiple mysensors platforms in home assistant. About 5-10 people has been contributing to the mysensors component in home assistant over time.
There's also the pymysensors package (not my creation either) that interfaces mysensors and home assistant. It's actually this package that holds most of the mysensors specific logic, like smartSleep. Here there's also about 5-10 people that has contributed.
All help and feedback is welcome!
