Just attach the bluetooth mic/speaker device to RPi bluetooth
And that will work as a satellite that reacts to wake words?
I dont think anyone has gotten that to work yet.
Been googling this but can’t see to find how to do it. Any pointer?
It just acts like a plain microphone / speaker for the system whatever you have on that system should be able to use it as such.

Here is my esphome config for the esspressif esp32s3 korvo-1 development board. I ended up getting it since an S3 Box is impossible to get. It works, all the LED’s work as they should but it could probably use some tweaking to take full advantage of the hardware. Now I just need to design a 3D case. Best part is it has speaker outputs for low power or powered speakers and a 3.5mm output for pretty much anything you want to hook it into for sound output. No onboard speaker though.

For anyone looking for an elegant, 3d printed (that is covered with a textile speaker grille) enclosure for the Korvo and Korvo1, have a look at my WIP over here Far field satellite with an Elegant 3d printed enclosures
I’ve been following this thread, but it would be great if someone could wrap it up, with some simple to follow instructions on the board in regards to how it all finalized with what works best. both for the S3 dev board and the regular esp board.

Hello, with my ESP32 N16R8 I was able to control the RGB LED, use the wake word, the actions are well done but despite all my attempts I did not manage to output sound via the Max98357 either in speaker mode or media_player. So also a taker of a connection / code that works with the ESP32 S3 
Here is a link to the code I use on N16R8. It works, but has a few false positives when the radio is on in the background. So need to do some fiddling about with settings.
Thanks to BigBobbas
As an update to my crackling speaker issues, I replaced the max98357 and it was fine. So one non working amp.

hi
i seen your post, i tried the same setup with my esp32 wroom32 but have issues with the media_player, when i play a file the esp32 crashes.
is the ESP32-s3-N16R8 Dev Board better than the “ESP32 wroom 32” ?
how do you make it which the command to stop the music?
i read something about custom commands with the assist, or is it possible to mute the sound when the wake word is speaken?`
Everyone with noise problems… it is the 3.3V or 5V supply voltage… I run an OrangePI 2W with USB Audio and it was noisy. The solution is to Boost 5V to 8V and use an analog Voltage regulator such as 7805. I cut the red and black cables in an USB extention cable being careful of the data wires, and connected the MT3608 Boost converter and the regulator 7805 supplying smooth voltage to the USB audio module. Be aware if you need 3.3V you need a 3.3V regulator and no Boost converter if you have 5V somewhere. For me the noise disapeared completely /Mikael

Well, I was wrong, i thought the repository was handling microwakeword and it wasn’t, here is the updated working esphome code for microwakeword. Also, if you flashed it with the board as esp32-se-devkitc-1, it only formats as either 4MB or 8MB, I was pulling my hair out until I realized the PSRAM was more then double the ROM showing in esphome. It said the BIN file was 19xxx bytes and the flash was 18xxx bytes so I automatically assumed 18MB when it’s nowhere close to that… Just had to specify the flash size, one line…
Remeber to change API key, and wifi as I have it statically IP’d. Also, it points to a non existent file for the firmware, because of this, it shows up as red in esphome but everything works and you will always be prompted to install a “new” device. Just leave it alone, don’t adopt it. From what I understand, it will need to be added on the esphome side and there has been a feature request to add it. If that will happen or when, if ever, I have no idea. If you comment it out, it fails to flash… Everything works without issues although I’m pretty postie the buttons don’t do anything. There are some warning during install and they are way above my skill set as I am not a developer but can cut and paste other peoples code and mess around with it and usually can get things to work. Most credit goes out to whoever wrote the repository I am pointing to because I never would have been able to do it without that

Many people have already written about the fact that crackling and noise are primarily caused by interference in the wiring between the ESP and the sound module board. Because it is not just a relay or LED control wire, but a digital serial data bus operating at high frequencies. The best solution is to use no wires at all. I’m sure everyone has these things, they are usually bundled with the boards. I made such an assembly, I’m sharing the pictures. No noise when turned on, in operation, crystal clear sound in music and voice.
In my opinion, this is more reliable and compact.
The sound module board (amplifier) should be powered directly from 5 volts, the microphone board from 3.3 volts. I took out a separate type-c power connector and soldered it to the esp directly to the inputs of the 3.3 volt step-down converter (don’t mess it up). This gives the least amount of voltage dropout.
And yes, I confirm that microphones can be easily killed when soldering. In my case, flux got into the hole and I couldn’t get it out with alcohol and other cleaners.
p.s.: And another mounting option (this is not for a speaker, but as an adapter to a 5.1 system)

I have a question. If we use a Bluetooth speaker like the one in this build, why using audio output through amplifier (that may generate noises and headaches)? Can we use instead the bloototh connection (that is usually available in all ESP32 boards) to connect to the speaker itself for audio output? Hoping, by doing so, we can use the volume controls on the speaker without supplementary programming (I’m guessing), and remove the problematic amplifier from the build. Esp32 board will be used for wakeword, incoming audio through microphone and led lights. Can it be done?
I don’t believe this is currently possible. Most examples I’ve seen or used turn off Bluetooth when microwakeword is enabled. Someone in another thread said you can output audio to a media player, but it has to be defined in the ESPHome configuration and you may or may not have to allow the device to make HA service calls. Just be sure to enable it on the device after it’s added to HA. You would use one of the 2 services below

I have had some time to look at this. And the microphone part is not possible, unless you have a device with headset_head_unit profile. PulseAudio does not support handsfree_head_unit profile, which most Bluetooth speaker would have, like mine. I could use the audio output of the speaker with the add-on, but unfortunately I couldn’t get the microphone work through Bluetooth.
If PulseAudio would have ofono as well, then it could work, but I guess, that is a different issue with HAOS.
Honestly, I wish I knew because on my Korvo-1 there is an annoying popping sound before playback. I believe it’s because there is a pin and if it detects something plugged into the 3.5mm jack it’s high and if not it’s low and uses the jat output to a non passive (powered ) speakers which nobody has gotten to.ork. S3 box is gone and this is decently priced.
It’s just super annoying but looking at alternatives the M5Stack CoreS3 which has the yaml out there for being a voice assistant. It also has several modules although.Im not sure how ESPHome would handle them as they have an RCA module with left and right channels. They also have one doe Ethernet. Problem is it can’t just be plug and play in ESPHome. They do have the code out there though and it’s essentially an S3 box made by m5stack but you can stack modules like batteries to Lora modules, only 2 that interested me are below but like I said, it won’t just be plug and play.
I doubt this will ever do audio over BT. It’s listening for the wake work ever 15ms or even higher by default and uses the PSRAM to hold on to what it heard just to see if it was triggered so listening for the wake word is it’s full time job. I guess not once your in the actual voice pipeline as it’s just STT and TTS but I’ve always gone by the S3 box examples and they disable BT once they connect to HA so it won’t take up resources (per comments in YAML). The thing is the below might just end in the same situation because outside the S3 boxes it seems hit or miss. I have read lots of people ha ing some audio issues of various degrees
And after typing all that out, that has audio issues also according some GitHub discussion. Try the below, it might work but I haven’t tried yet. I e watched a few of his videos and so if he said he has it working I don’t doubt him.
Honestly, I ended up spending 10 dollars and I am going to try this because while vice commands are nice, they certainly still have some issues. I’m sure they will get worked out over time but 8 dollars for physical keys to run anything would be nice to have around and you can do that with.a direct WiFi num pad, just need an available USB port on your HA server.
Ive moved on from these ESP32 options to the Wyoming Satellite. They are much better.
Oddly I just figured out how to do it but yeah, Wyoming satellite can actually run Openeakeword and some other stuff like Wyoming and piper on the pi. which was never ported to ESP32 and I honestly don’t think it has the power to. Just leaving this here for others in case they run into this. You also have to go to devices, then ESPHome, click configure on the voice assistant and check allow this device to make home assistant service calls. After that I unplugged the 3.5mm audio output. Problem solved.
