I was able to get Swagger running on my hub, but I had to use the IP address rather than the “name” of the hub. These are blinds that were installed in August 2022. I have used the app on the my phone to update both the gateway and the blinds.
Using the commands above, I’m now able to get a full working swagger API for my blinds.
Enable Swagger on your hub: http://<hub-ip-address>/gateway/swagger?enable=true
Get the Swagger results: http://<hub-ip-address>:3002
I’m able to list blinds, jog them and correctly set their position.
I think @DocBrown’s solution are a reasonable intermediary. But I’m a semi-retired programmer with two sets of these blinds (home and cottage), so I’m happy to contribute here.
