here is the yaml, everything works without any issues. I tried looking into the firmware thing and it looks like it has to be added on the esphome side and there has been a feature request put in. If it will ever happen is another story though. I did get some warnings about the microphone and during the tensorflow.
Also, it was actually working with OpenWakeWord still until I looked into it. I realized after looking into the repository I am pointing to and if has an option to work with both. When looking more closely at the logs, it wasn’t, they are totally different (as far a cli output) when being triggered and processing a wake word. Remember to create a new pipline with no wake word defined. If you use your default, I believe it will use OpenWakeWord. Another fun thing is since I set the board to esp32-s3-devkit-1, it formatted the ROM at 4MB or either 8MB. It was saying 19344 bytes was to large for my flash of 18345 bytes, which I interpreted as 19MB and 18MB which is obviously WAY off. I probably spent a good 2 hours trying to figure this out when I noticed that when I got that message the PSRAM was more than double the size!!!. So all I had to do was add one simple line to specify flash size as 16MB. DOH. Oh well, it’s working, that is all that matters.
Remember to add the API key below and change wifi if not using the same secret format I am using also. For some reason, a few releases ago all the LED’s stopped working. I don’t know if if it’s just a weird LED thing or if only one mic is working. I was pretty much relying on that repo for a lot of stuff because he had the actual espressif files with the includes to the driver files and specific hardware firmware. Stuff like that. So, you could just specify the mic and one of the mic gpio’'s, but I doubt it will work out as well as this because it won’t be utilizing all the hardware. I honestly can’t say if all of it is working with this either. The 3.5mm output works fine, haven’t tried the speaker output and all my speakers are passive, I also don’t have a jst adapter that will fit it either.
Just remember, you may forever have a new entity wanting to be adopted after this, just leave it alone, even though it shows up as red it just works and outside someone adding the firmware to esphome, it will always be that way. What is really odd is there is a line in there that points to a github url that doesn’t exist for the firmware. If I comment it out, flashing fails, so it has to be in there, even though the the file doesn’t exist in the main esphome repository it’s pointed to 
Lastly, it took over 600 seconds to compile, and I am running HA on a 7 year old intel Nuc with an I5 so if you are using a raspberry pi 4, it could take a while longer so make sure to just wait until it flashes or times out. Actually , if it’s your first time flashing it you will have to plug it into a PC or the HA server so you will see the CLI output. The tensorflow part takes quite some time. You have to hold the boot button when plugging the power cord in to put it into boot mode. The USB cable for for communication should already be plugged into your PC when doing this.
