The Doppler sandman shows as a device in the Alexa app under "Echo & Alexa" as circled in blue.
When trying to add the device to a Smart Group it is not listed. Refer to the 3-side-by-side screen images below. The yellow box indicates the overlap in images 1 and 2. The purple box indicates the overlap in images 2 and 3. However, the "Doppler Smart Button 1" and "Doppler Smart Button 2" are listed, which are from the "Sandman Doppler"
Any thoughts on how to correct this?
