Hi,
I have multiple always on PCs in multiple locations in the house. I would like to listen the microphones of these PCs to get baseline for volume and tone. I have figured out that it could be something like this:
- Start ffmpeg process
- Run the process for 1 minute. Calculate max volume and avg tone in Hz.
- Send volume and tone with MQTT to HA.
- Restart the process
Have anyone tried anything similar? This would allow applications like:
- Detect any unexpected noises when house is empty.
- Detect firealarms
- Detect if HVAC or other machines start generating unexpected noises (and those are about to break soon)
I have seen some partial solutions on the web but nothing I could use out of the box with HA.
