I bought an Amazon Dot for Black Friday. Took an evening to setup and I have 60 some devices/scenes/programs. Worked very well. Was very happy.
This evening I tried to turn off the living room lights, and Alexa replied "Command doesn't work for device living room lights". I tried a couple of more commands, and got the same results.
I opened the Alexa app on my iPhone, and checked the "Smart Home" devices. Instead of my 60 some devices, I had 90 devices. There were 26 devices that weren't mine. They were named in French. I decided to try to clean things up, so I told the app to "Forget all devices and groups". They I clicked "Discover devices". Now none of my ISY devices show up. Only the 26 French devices, and my 3 Nest Thermostats.
I only have 2 skills: ISY and Nest.
It appears that the Alexa ISY skill somehow got linked to someone else's ISY.
Things were working this evening around 6PM. But they were broken around 10PM. I didn't touch any configurations in between.
Sorry if this was covered in another topic. I couldn't find one.
