These are a great addition to a “smart” system. However it adds yet another ecosystem to manage. Since there is no Wyze solution on the horizon, could be a possibility though.
My only concern is management and regulation of the duct pressure and net airflow when the system is active. If they don’t have a way of showing this or producing a warning notification, it could be really easy for a user to damage their system by closing off too many registers in unused rooms.
My system is a newer retrofit into an older home (1953) that replaced an oil furnace and added AC. The previous owner did not splurge. It is a cobbled together network of old and new solid ducts and lots of flex-duct. I have been under the house many times shoring up shoddy workmanship and downright ignorant design shortcuts. They used more Foil Tape than they did screws, brackets and hangars! The primary trunk duct they hung actually fell from the joists and was sitting on the ground. They used 1\8" duct screws to attach it to the joists!
If I over pressurize my ducts by closing too many registers, it will blow the ducts off or at least blow the tape out. Worse, I have seen HVAC systems ruined from blocked airflow. Most users don’t consider the importance of proper airflow and duct pressure.
This might be something I consider down the road, but I have too many projects on my full renovation wishlist now to make this a priority. Nice to know it is available though.
I did vote for this Wishlist topic.
