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.
