I like the app’s simplicity and device setup is super easy.
The app could use some improvements. For example, Dyson products aren’t in the library at all so you have to “teach” it with the original remote. And you can’t move a device from one “room” or group to another. Also, you can’t clone a device which is odd. And if you teach it then the app labels everything as “other” and you can’t rename it so then have to use rooms to separate “other” devices to avoid confusion.
The devices themselves are good - simple, to the point, and easy to deal with (for example changing the battery is a breeze). The price is the only drawback - getting them at $20 each on discount is ok ($10 or 15 would be way better) but $30+ apiece is overpriced.
I would still recommend this app and product - I myself have bought 7 of them to be able to control my Dyson fans. Until I find something better then I’ll keep using this and buying more devices/remotes.
