I have two Amazon Echo devices installed in two rooms. I have created groups and added devices of the rooms to their respective groups. But I have some devices with the same name. For example, I have two devices named Light, one in the bedroom and another in the office room. When I try to turn on/off the light of the bedroom by speaking into the Echo device of the bedroom, it turns on/off the light of the office room. When I speak to the Echo device of the office room, it turns on/off the light of the office room, which matches with the normal behaviour.
How can I make Amazon Echo devices to control the devices in the same group, in case of duplicate names among all my devices?
