Can someone please paste the configuration yaml for an M5Stack Atom Echo that is currently working as a voice assistant satellite for Home Assistant using open wake word? (remember to redact your private data)

I installed a bunch of these Echos following these instructions back when they were first introduced. They have tiny little speakers which are essentially useless, but I routed the output sound to a media player in the same room. At that time the only option was to use open-wake-word - Nabu Casa even provided instructions and virtual-gpu resources to train your own wakeword, which I did.

The Echos worked great with my own custom wakeword for a long time!

Then sometime within the past year they stopped working. Their "wake word" entity is unavailable. I know Home Assistant came out with micro-wake-word, but I wasn't aware they ended (or broke) the open-wake-word functionality. I'd love to get my Echos working again - I'd prefer to use open-wake-word, but if the only way they're going to work now is with a pre-set wakeword, that's better than no voice assist at all!

Thanks for any help you can provide.
