Switching to V3 created duplicates

[Dannodapter]

After receiving the V2 Amazon notice of sunset I enabled the V3 skill.  I removed the V2 first.  After doing this I ran device discovery.  The problem I'm having is that Alexa created a new device for any alternate spoken word. What happens with numerous devices is Alexa says "A couple things share that name, which one did you want?  I then repeat the same thing and she turns the light on.

Looking in Alexa the only option is to disable a device and then I lose that ability.  It seems there is no option to remove all devices which I thought might work if I then searched again.  I did try removing the alternate for 1 device and running discovery. This worked and the duplicate device was removed. I don't want to lose that ability but it is also time consuming. 

I was thinking about saving my ISY data > removing everything > Alexa device discovery > restore ISY > run discovery again. 

I imagine many do not use alternate spoken commands but has worked flawlessly when for example someone says turn on kitchen ceiling and another says kitchen over head as an example.

Anybody else run into this?

Here's a few tips regarding Alexa.

When troubleshooting, always use the Alexa app, instead of voice commands. This way, you are sure about what device is being controlled. When controlling via voice, Alexa may be confused with a device or room using a similar name.

If you find you have duplicates, you need to delete them from the Alexa app. You may be tempted to start fresh and delete your mappings on portal, but there is no need to do that. The only case where it may be useful is if you are mapping an ISY node that no longer exists on your ISY (or eisy/polisy). 

When using V3, when adding/editing/removing a mapping, it should be updated directly in the Alexa app. There is no need for a device discovery. That's if the skill is linked. If you change your mapping while the skill is not linked, then when linking it will get discovered.

I don't think the problem you are having is the alternate spoken. Alternate spokens are treated exactly the same way as the primary name you gave. Using alternate spoken just creates additional Alexa devices mapped to the same ISY node.

One thing to watch for are Alexa scenes, especially if you had some when using V2. Alexa scenes are kind of hidden. So if you have an Alexa devices with the same or similar name as an Alexa scene, then Alexa will see multiple device with the same name. That's why it's important to first test controlling devices directly with the Alexa app - you know which one you are controlling.
