I ended up adding cloud: to my configuration.yaml and quickly found that tons of my groups and entities were suddenly listed in my Alexa account’s Smart Home devices. I’d like to clean all of that up, so I edited/added the following to configuration.yaml:
cloud:
alexa:
filter:
include_entities:
- group.arlo # Until we're ready to actually give Alexa something
Unfortunately, I still see the huge list of smart home devices that Home Assistant linked over the first time. I’ve tried manually deleting them, but they reappear. I’ve tried unlinking the Skill in Alexa, then deleting them - yet they still reappear.
I was having issues with Alexa picking up old devices after deleting them…What I believe now is that the amazon servers do not clear cache daily. If you delete all devices from Alexa and give it a few days or longer when you re-add they will be gone. The question would be how often they purge the cache.
Finally figured out how to get it all fixed. I had to go to alexa.amazon.com, Smart Home, and then click Forget All at the bottom of the page (after I’d already either disabled the HA skill or setup the proper filtering in my configuration).
