I am developing smart lights using the BrightnessController. I am sending proactive updates to Alexa and it seems to be responding to Query directives. I can see the states and brightness in the Alexa app just fine.
However, when I try to query the state using voice commands (e.g. "Alexa, what is <device name> set to?") I get the response of "<device name> doesn't support that." Is there a setting or extra configuration that has to be sent to in order to enable voice commands?
