[APP][Pro] Gree HVAC app

Thank you for your feedback :+1:

It could also be a good idea to introduce a subscriber model at Homey. I would be willing to pay for some apps. As I understand it, the options are for the manufacturer to make it themselves or to pay Athom to make the app. In applications created with the Community model, you can donate, but as @aivus said, so few donate. Athmon could add subscription features to the Community model if the developer so desired.
