I have upgraded to the new Alexa+ service (AI version of Alexa), and its now telling me the existing skill (ISY Optimized for Smart Home V3) will no longer be supported in a week. Every time I give Alexa a command for an ISY device, it executes it, but then says:

"The skill for <device name> hasn't upgraded to support the latest version of Alexa. You will no longer be able to use this device with Alexa starting November 4th"

How can we get an upgraded skill that is supported by Alexa+? I don't want to lose all my device control via Alexa. The only alternative is to unregister for Alexa+ and go back to the original Alexa experience.

Apparently they have new SDKs for developing new AI compatible skills.

Add a few clarifications and additional info about the new SDKs available.

What is being removed on November 1st is support for the Amazon Smart Home API V2. This used to be the case for our older "ISY Optimized for Smart Home V2" skill.

The "ISY Optimized for Smart Home V3" skill uses the Amazon Smart Home API V3. This is still supported and the only current way to implement a Smart Home skill for Alexa.

When using Alexa+, this still works with smart home skills. The new "AI-native SDK for Alexa+" allows to develop custom skills. I guess it could be used to control devices, just like the older Alexa custom skill API could do. But regardless, smart home skills using the V3 API is still the current way to develop smart home skills.

Now, I have had many reports of users receiving the warning you mention. I do not know for sure why. I believe this may happen if you used to have the older ISY Optimized for Smart Home V2. Either it's still there (along with the V3 skill), or there's some remnants of the older devices existing in the account.

In preparation, make sure the skill you are using is "ISY Optimized for Smart Home V3".

On November 1st, if you see some devices are no longer responding, please do this:

• Login to the Alexa app, test the device there.

• If you see it is not working, delete it from the Alexa app.

• Ask "Alexa, discover my devices".

  • This should recreate the device in your Alexa app based on the configuration you have on my.isy.io.

  • If it doesn't, login to my.isy.io, look under Select tool | Connectivity | Alexa.

  • Make sure that your device is there. If it is not, create it. It may be that device was created a long time ago using the V2 skill. With the V3 skill, the device discovery will create a V3 device in your Alexa account.

when I added the V3 skill, I looked for the V2 skill to remove it and it was nowhere to be found. Perhaps there is a way to find it and remove it?

and by the way; its actually "after November 4".

Yes, I also had the V2 skill earlier and when I switched to V3 I always felt the V2 skill was still running but it was not listed in the app, and there seems to be no way to delete a skill. Having both active could explain other strange behaviors. I guess I will see what happens after Nov 4, hopefully it will continue working via the V3 skill, and I do appreciate the great writeup from bmercier with the tips.
