I`m a little frustated now, since I can not find my error. Hopefully someone here can help me out.
In my SmartHome-Alexa-Skill I implemented the "alexa-thermostatcontroller-schedule Interface (including the Alexa.ThermostatController). This interface can not be accessed by voice-interactions only by the alexa app. But there is the problem, the "Thermostat Schedule"-option (like in this article https://www.amazon.com/-/de/gp/help/customer/display.html?nodeId=GT936T2J7AKMVYFW&ref_=hp_GMCQK6C7JTCG6NCA_c_Program-Your-Home-Temperature- ) is not visible in my alexa app, only some manufacturer informations.
My Alexa.StateReport and Alexa.Discovery response looks the same in like on the developer-documentation.
I changed also all language settings to englisch (since my skill is developed for german commands, but this should not matter)
Can some one help me out please?
