Lights control with no neutral
Shelly 1L is a Wi-Fi-operated smart relay that requires no neutral wire, making it suitable for all electrical installations! Easy to install in less than 10 minutes, Shelly 1L can grant you full control over your home lighting and help improve its efficiency. By using smart schedules and remote control, you can ensure that no lights are left switched on while you're away.
Shelly will set the lights on the porch to automatically switch on around the time you come home from work, and together with a motion sensor, never let you walk in a dark room again. And don’t worry – light switches can still be used manually to suit the needs of everyone in your home.
Endless use applications
Many light switches are wired with no neutral present, which makes them difficult to automate. Shelly 1L can convert any existing wall switch into a smart switch. You don’t need to change the wiring, run new cables, or anything else - just put it behind an existing wall switch. There is no limit to the type of lights you can use with Shelly1L – LED, CFL, Incandescent, Halogen, or Luminescent lights can be controlled.
