Many not intelligent appliances communicate with us via Audio with beeps and sounds and fire alarms. Those sounds are never as cool as R2D2 and are overheard frequently when it is too loud, nobody home or in the basement.
Some voice assistants can react on those sounds but I would prefer a solution directly in homeassistant.
Wouldn’t it be cool if we had the info about it in homeassistant and could trigger notifications and so on.
There could be an implemented database and perhaps also a recording feature to classify new appliances. With the help of the community this database could grow very fast.
