- Find out your model does not have the same points, since it is a different version. Contact JBL, Harman Kardon, ask nicely for a manual, be denied and disappointed of your wasted time.
Leave it sit for a couple of months, be sad.
-
2 . Then just put it back together as before, but before just for fun put some wires against random points and be happily surprised that something has happened. Try again and log what happened. Some turned speaker on, some controlled volume.
-
Regain enthusiasm. Attach your ESP to the points you found
To your surprise it works.
Try to put it back inside the case.
Just shove it and hope no wires come loose.
- Nobody suspects that one is not like the other.

Parts list:

- Lolin Wemos ESP32S3 mini
- Max98357A I2S DAC
- INMP441 MEMS MIC
Hijacked the “Pair” button to trigger voice assistant, but now since wake_word is available my HA is unstable and reboots every 10 minutes 
YAML is nothing special, just the base config, media_player, microphone, voice_assistant, sensors and switches for controlling the JBL. Already forgot the touchpoints for my version, not going to risk opening it again and loosening the connections.
