Hello

i try your component and if i use advanced example code i have 121db and if i speak or clap my hand nothing happend.

I try the minimal sample code and i get 104db and same, not a lot of difference if i speak or clap my hand close to the mic nothing change.

I use a SPH0645 like this :

i2s:
  bck_pin: GPIO23
  ws_pin: GPIO18
  din_pin: GPIO19
  sample_rate: 48000            # default: 48000
  bits_per_sample: 32           # default: 32

any idea please why i doesnt work?

Now that ESPHome has an official i2s_audio component https://esphome.io/components/i2s_audio.html do you have any plans to update the sound level meter to use that implementation?

Hello,

First thanks for the nice component. Works very well! I use it as a barking detector when we're not home ;)

I faced a small issue : despite having is_on: true in the yaml (as defined in the example config on the repo), when the ESP boot the sound level meter is turned off. I have to use the switch in HA to enable it.

While digging in the logs, I saw that the switch has a default restore mode to off. Adding restore_mode: ALWAYS_ON solved my issue. But his makes the is_on: true parameter useless (in case the switch is configured). So maybe there's a nicer way to work around this or a small information to add to the the docs/examples.

Hope this helps.
Thanks again for the nice work!

Olivier B.

Hi.

I know this is not the purpose of this cool project, but could anybody think of a way to capture the audio and stream it to Home Assistant, so we can feed it to any media_player device?

Voice Assistant already does it, but I cannot find a way to use the audio for another purposes apart from STT or even replay it in HA. Thus I'm looking for another approaches, like streaming to FFmpeg integration or something like that.

Any ideas are welcome. Thanks!!

Hi, thx a lot fort that !
I just use the dBA peak sensor for my needs, with a 0.1ms refresh time.
Is it possible to have a boolean switch to turn the sensor on/off, to avoid to send datas when I don't need ?
I don't know if it's possible in the yaml config ?

Hej I have an issue that it is only working with wrong channel. f.eks. when i set L/R to GND so the channel should be left but it is only working with right channel which is teoritically wrong. and the lowest i get is 75 dBA in a quiet room which is totally wrong.
Do you have any tips that i can do?
I am using INMP441 mic and ESP32 devkitc v4.
Have you had also those issue when u working with Ivan's code.

Using an Olimex esp32-c3 with an INMP441. Im not able to get any measurements:

Max always reports: -256.29 dBA
Min and peak are on: -inf dBA

I've tried switching left and right as in #10 .

The hardware does work with this Arduino code: https://iotassistant.io/esp32/smart-door-bell-noise-meter-using-fft-esp32/

Any tips on how to debug further?

hey buddy
I hope that u can maybe help me, everything is working fine but when i implement wifi somehow it is not working with freertos i get constantly this error:

WiFi Connectivity Implementation

This C++ file manages WiFi connectivity using the WiFi library and NeoPixel feedback.
It includes functions to connect to WiFi networks, handle multiple network options, and indicate connection status.

Purpose:

• Connect to available WiFi networks using stored credentials.
• Provide feedback using NeoPixel LEDs to indicate successful or failed WiFi connection attempts.

what do i do wrong

Hello,

I'm trying to use this component with AtomS3U - SPM1423, but this has only MIC_CLK & MIC_DATA pins.
Any ideea what to do with the ws_pin? It looks like it's mandatory.

I tried also this external mic (based on the same chip) - pdm - the same, the WS pin is missing.

Regards,
V

Sorry to bother, I am fairly new to EspHome and have little skill in programming. I am running EspHome on a Home Assistant Yellow.
My aim is building a small and cheap dnms device with solid measurement quality and good wifi. People in my town are asking for this to record their noise environments. I have selected a seeed xiao ESP32-S3 with PSRAM and a ICS43434 mic for this and want to send measurement data to sensor.community for general logging and make this data available to others like our RIVM and city council.
Searching for the right software for this I found your topic.

I copied and tried to install your sensor-community-example-config.yaml but I get compilation errors pointing to wdt functions/files not found.

Could you point me in the right direction to get your yaml installed?

Best Regards,
Peter
