Hello,
I have an M5StickC plus that I want to use as a voice remote for the new Assist feature, just like in the example with the M5Atom Echo, but on a StickCplus.
Is this possible, and if yes, how?
Thanks in advance
Aaron
The stick has a microphone, so you should be able to use it at least for that.
No speaker, though.
What is your level of “how”? 
@koying My level of “how” is that I don’t know how to set up the microphone on the StickCplus in ESPhome (the pin assignment is very confusing for me) and I need the YAML for the mic.
Thanks for your help
Aaron
The base YAML would be media-players/m5stack-atom-echo.yaml at 836631e8ca446c84485bba2199f21fdfb398ba89 · esphome/media-players · GitHub
Remove everything speaker / media player related.
GPIO-wise, just play with it
How far along have you gotten with this? I decided to break out my old Stickc and install the voice stuff on it. I would like the response printed on the screen but I have no idea how to do that. It prints in the log so it should be possible. This little thing would make a nice little Home Assistant remote since we don’t have a wake word option yet.
I initially tried it but my problem was that the pins of the mic weren’t known
The problem is that we don’t know the pins for this:
Which is required when using a mic
any progress so far? thanks
I found project - M5StickC with speaker hat. Could that hat be used as speaker function?
I also have one of these and would love to use it as my voice remote. Just chiming in to bump and follow this thread.
Hi,
I built a barometer with the M5StickC Plus2 and an ENV III Hat with ESPHome.
I’m going to try a voice assistant with the M5Stickc Plus 2 and an SPK2 Hat. I’m waiting for my parts and to assemble this. I’ll keep you informed.

Hi,
I managed to get the speaker (SPK2) to work with this configuration to make a media_player.
i2s_audio:
i2s_lrclk_pin: GPIO0
i2s_bclk_pin: GPIO26
media_player:
- platform: i2s_audio
id: media_stickc
name: Media Player
dac_type: external
i2s_dout_pin: GPIO25
mode: mono
But for the microphone, I can’t do it yet. This configuration doesn’t work.
i2s_audio:
i2s_lrclk_pin: GPIO0
microphone:
- platform: i2s_audio
id: stickc_microphone
i2s_din_pin: GPIO34
adc_type: external
pdm: true
Yes !!!
I managed to get the microphone to work. I’m doing some more testing and will share the code.

Could you please provide the full YAML file for the Voice Assistant setup you showed in the picture?
I would like to replicate it, also like the answer being displayed on the screen. I have one question though:
Are you able to turn off the screen completely from within HA? I would need that functionality because even with nothing displayed the back-light is still on…
Best regards
Aaron Eisele
Would this also work with the original M5StickC plus (non-2 model)? I only have that on hand atm and this would be the perfect project to give it a use
Normally yes, you will need to change LED port on the GPIO10 (GPIO19 for the Plus2).

Have you had any luck getting the M5StickC Speaker Hat to work with the M5StickC PLUS v1.1?
I have been banging my head against the wall because the Media Player shows up in Home Assistant but sound no comes out of the speaker.
I have reduced the code to the BARE MINIMUM to test the media player.
I’ve tried various combinations of GPIO pins 0, 25, and 26…the result is still silence.
