That means you are missing a neutral wire. It’s usually at the light fixture box. You have 3 options.

  1. You can install an on/off relay module at the light fixture box. Aeon, Emerwave and a few other brands.
  2. You can install a dimmer module behind the dumb switch. Aeon nano or fabiro
  3. Lutron Caseta dimmer switch but you will need the lutron bridge.
