Reduce unnecessary monthly costs with Shelly smart lighting solutions. Shelly Pro 4PM can measure and control four separate light circuits and give you full control over common spaces such as halls, garages, and storage rooms, which usually have their lights constantly switched on. Now you can make them energy efficient using Shelly Pro 4PM's built-in scheduling and scripting functionalities. To fully automate your premises, add Shelly Motion2 to switch on the lights automatically when someone enters, and its pre-set smart timer will switch the lights off once the premises are empty.
