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?
