Appliances giant Haier reportedly issued a takedown notice to a software developer for creating Home Assistant integration plugins for the company's home appliances and releasing them on GitHub.
Home assistant does not, but Haier would rather you use their proprietary SmartAir2 app that vacuums up every tiny bit of personal data for resale, and could potentially turn into a subscription service later.
Mind you smartair2 has a 1.4 star rating on the play store if that tells you how well any of their software and devices work lol
The software is free, and you would never need to pay anything to get set up great system for yourself. In addition to that, they also offer a service that you can subscribe to that gives you some benefits. You can replicate all the functions on your own, I believe, but the service makes it extremely simple.
IMO, it's also worth the yearly cost for voice integration with Google Nest/Home or similar devices. Both can be done without paying but it's so much easier and I know it'll be supported over time.
