Somfy Tahoma Switch?

I’ve had the misfortune to purchase a Somfy Tahoma Switch and after several months of arguing with their tech support finally managed to get it working on two separate mobile phones. I’m trying to following the instructions @ Somfy Open API Developer Portal | APIs & Docs but I can’t get past this error message either authenticating via Home Assistant or directly using Chrome or Postman against the app I created.

Does anyone else have one of these boxes and managed to get it working with Home Assistant?

You can use iMicknl/ha-tahoma: Custom component for Home Assistant to interact with smart devices via Somfy TaHoma or other OverKiz based API’s. (github.com) in the mean-time.

Hopefully this will be added to core in the coming months.

I did your suggested trick of setting up a scene - I’ve now been able to set up the Somfy integration using the cloud setup but specifying the OAuth credentials in configuration.yml was still not working.
