Anyone know of any sound level sensor that can be linked into HA?
Can be mains/USB powered or battery powered. Zigbee or Wifi. Need to be as compact as possible, hence wanting off the shelf solutions.
I want to install sound level detector in my hallway, near the front door. I hear there are burglery going on in the neighbourhood, where they knock on people’s doors at night while monitoring the house, if no activity is seen, they come back later to burgle the house.
trigger if high sound level is detected
condition: away mode or night mode is on, hallway and stair motion sensor clear
action: randomly turn on light bulb(s) in bedrooms for a short random period
