Had my eye on these since they got announced at the beginning of this year. Installed one last week and just put up two more today. They need a minimum 1.5" diameter tube to fit inside of which my cheap home depot blinds didn’t have. I just got a 1.5" piece of ABS plastic tube, cut it to size, and re-rolled my blind material onto it. Works a treat.
They are a bit pricy but so far they work well and integrated pretty easily into HA via the HomeKit Controller integration. Apparently they can also work over Thread but I have yet to look too much into making that happen.
