Hi, is there a way to add a microphone for sound level measurements to the outdoor monitor? I’m also interested in measuring sound pollution. Thanks

I see that the Sensor.Community group is developing a noise monitor in addition to their air quality monitors but the project appears stalled unfortunately.
Looks like they are using ICS43434 I2S Digital Microphone from Pesky Products on Tindie
It is I2S and it looks like ESPHome supports this, but I’m not familiar with this protocol or know what ports might be needed
I²S Audio Microphone — ESPHome
It can also be added with Arduino code, but I’m not aware of this being on the AirGradient’s roadmap, at least not on the indoor model, so I don’t expect official support coming from them. But if you wanted to modify the code to add the feature, it would be possible.
