so small !! I didn't expect it to be such a small thing :) beautifully packaged, the case is great with a practical button.

The Echo was supposed to become a voice assistant quickly and easily in Home Assistant (OS). At first glance, it worked well (ESOHome integration). During the first language test, the module crashed during the second wake word (visible in the log). Reproducible. The i2c bus is shared between the microphone and the speaker and is not released properly. Unfortunately, I have no idea where I can get proper support in this regard. I trust the people who maintain the package (which is read into the SRC) that the problem will be solved sooner or later. At the moment, the Echo is a dead device. My criticism: A direct contact person (technology) for the EchoS3R should be there. The Adafruit 5639 High Power Infrared LED Emitter Module is excellent. The GPIO I2C pin expander Adafruit 4886 is for the "tinkering box". I trust that it has already proven itself many times over.
