From the developer:
Signals for HomeKit comes with a convenient way to communicate in your home without all the shouting. Signals works with any of your bulbs, switches or outlets with lights attached. Whether you have kids, or someone in the family with a hearing disability, Signals for HomeKit can help quiet things down, and keep the conversations face to face, rather than shouted through the house.
