I have two home assistant set ups and having this issue on both.
I discovered blueprints and used
“Do something when Alexa Timer has expired”
Worked great
But last week all the Alexa sensors are showing not available.
Is this a issue with the new security patch?
Hi, i have the same issue. Hope someone can fix this soon.
The sensors still show unavailable but my kitchen timer turned on my kitchen LED tonight as I was making dinner
So I don’t know what is going on.
Have not tested to see if it was just a one time thing.
Hmm, now its working again. Maybe something was changed by Amazon?
I have the same issue.
