What did you end up going with for motorized blinds? I just bought a new house with a ton of great natural lighting and want to do this without paying an arm and a leg to get it done.
I used to use the similar ones from Somfy, but they were just too much of a pain in the end. The only thing I don't like about the iBlinds model is that there's no hard-wire communication option (I have 4 conductor wires with power and RS-422 at every window).
I'm surprised there aren't any commonly available blinds that include an internal tilt motor with external manual fallback. Bonus point would be if it also included a lift motor.
I ended up getting WiFi blind chain motors from Aliexpress. This allows me to integrate with the existing blinds that have chains. Also, if I ever need to remove them and go back to manual, it's easy.
Related: recently, I put up WiFi blind motors on all of them. With HomeKit automations, these now go up at sunrise and go down at sunset.
Has been an unexpected life-changer by bringing in natural light and boosting mood. I'd highly recommend it.
