Garadget Alexa

I have integrated Garadget with HA using MQTT. It works via the HA app but I’d like Alexa to be able to handle voice commands. In the Alexa app where you select via voice, is it not available. Power, open, close, and custom are selectable but when you do it say server unresponsive. I found in developer mode that the supported feature was 11, when changed to 3 it gave me exactly what I needed in Alexa. Whats is generating that 11? how do I save it to a 3? I have looked in the config but found nothing.
