I tried to implement the Smart home API ModeController to control Blinds in french locale fr-FR.
The discovery response is the one mentionned in the documentation : https://developer.amazon.com/fr-FR/docs/alexa/device-apis/alexa-modecontroller.html
The discovery is fine.
However, when I request "Ouvre volet" (Open blind), I got the error message saying that this feature is not supported by the device "volet".
Did I miss something ?
Thank you for your help
