Neo Smart Blinds is actually compatible with:
Control4, Savant, Indigo, IFTTT, Creston, Siri, Google Assistant and Alexa.
Nonetheless, I've found some possible indications of a local API. But I haven't found any documentation, so you'll have to contact Neo Smart Blinds team for the documentation.
For the local API usage, I think you may need their Neo Hub (needs confirmation).
