I too am having the same problem. I went to alexa.amazon.com and removed all devices and then pressed discover and its not discovering any HA devices/entities.
I thought I saw something yesterday about some infrastructure updates happening Oct 27 or 28 - don’t remember which. Maybe its related to that.
Hi. All entities that are supposed to sync with Alexa are without function for at least 4 hours. They are all shown as “unavailable” in the Alexa app. So obviously the “Home Assistant Skill” has a big problem since the maintenance. This is one of the main features of the Nabu Casa subscription. So please push this post accordingly if you have the same problem. Thank you.
Same here too, noticed it this morning but only got round to troubleshooting now.
Restarted Home Assistant, no change. Disabled and re-enabled the HA skill, no change. Removed a device and tried discovering new devices, it wasn’t found. Removed that device from Alexa section of Home Assistant Cloud and added back and ran discovery again, and it was found, but immediately says “there was a problem” again.
The power button in the Alexa app is able to toggle lights on, but not off.
