Duux, a premium fan (and other air conditioning) brand best known for it’s premium, wireless, battery powered silent fans has recently launched a range of new products, calling them Gen 2.
Sadly, this looks like sortof a closed system. The Duux app itself is still a Tuya Backend i believe, but it’s not possible to pair these products to SmartLife/TuyaSmart.
While it might be technically possible to open it up and replace it with an ESP/flash it, i’m not experienced enough nor comfortable trying that out.
Since they are a popular fan brand and people spend a whole lot of money for them, i think it should have it’s own integration.
