I have two bedrooms each with an RRD-6NA dimmer, an RRD-2ANF fan control and an Amazon Echo. A group was setup for each bedroom in the Alexa app and when I stand in one bedroom and say, "Alexa turn on the light" the correct light turns on. If I say, "Alexa, turn on the fan" suddenly Alexa doesn't know which fan I mean and wants me to add the name of bedroom. Have I configured this wrong? Is there a way for Alexa to treat the fan the way it does the lights? Thanks.
