Blind/shade/cover motors that use the existing cord

I’m looking to make my roller blinds smart. I have found a few options that use external motors which just work with the cord. Does anyone have any experience with any of these or others that aren’t listed? Specifically I would be interested in knowing more about the speed, the setup with Home Assistant and the general quality.
