As a contractor I have actually released an app on the Huawei store and added support for HMS. This application made around $60,000 every month in sales on the Play store.
After a load of hassle and weeks of effort we finally released on the Huawei store. It then proceeded to make around $20 per month. Suffice to say we didn't bother updating the app any more on there and it was a monumental waste of time and effort.
@rusalex2k8 you are most welcome to use one of the myriad of other major automation apps that support Huwei HMS. Please let us know if you find any
New Huawei devices are dead in the water and I'm glad because they break Android in many ways and caused me never ending pain.
