Our master bath has a triple gangbox for 1) room lights 2) shower can light & fan combo and 3) vanity lights.
I had a Monoprice dual-relay add-on connected to the #1 room light and #2 shower light/fan. I changed #1 room light to a GE 12724 Dimmer, and connected the relay to the #3 vanity lights.
Prior to making any changes, I renamed the Master Bath Light to Master Vanity Light. After changing the relay to the vanity lights, I installed the GE Dimmer and named it Master Bath Light (same name as when it was previusly connected with the dual-relay).
After running Discovery on the Echo, then trying to turn the light on, Echo replied “I found more than one device with the name Master Bath Light. Please give them unique names, then run discovery again…”
In the Echo app, I chose “Forget” on the Master Bath Light, then ran Discover again. Then, as expected, Echo could not find Master Bath Light when I tried to turn it on.
However, when I added the Master Bath Light back into the Alexa ST app, ran Discovery, then tried to turn it on, again I got the reply that there is more than one with the same name.
How can I get the old “phantom” device out of Echo?
