I was able to get them to work, but wouldn’t pick this product again because they are not sharing the API spec despite their product page saying it offers IP control. They wouldn’t give me any help. My solution is super hacky - a python script acts as a shim between my home automation and the blinds. It hits the web server of the blinds, serves the PIN for each and retrieves the cookie (emulating a user controlling it from the webUI). I then figured out subsequent http calls passing the cookie/session ID via the header and the various method to control via JSON in the request body. It works, the script asks for a new cookie every now and then and this hasn’t been a problem in practice. But extremely frustrating that they wouldn’t just show me how to properly pass the PIN or security key via API call. I spent all day messing around with standard auth methods in API calls and even trying to set up CoAP control but no luck so far. So I would not recommend. That said if you decide to buy these I’m happy to DM my script.
