Lighting

Light switch and switch

The simplest devices: something that is either ON or OFF. A Light switch is a light; a Switch is any other on/off device (a socket, a fountain, a towel dryer). Both behave identically.

At a glance: name, icon, and a pill-shaped toggle. The toggle and the panel glow orange when ON.

Controls:

ControlWhat it does
ToggleTurns the device ON or OFF. The switch flips instantly, then settles on the state the device reports.

There is no detail page — everything happens on the row or tile.

Push button

A momentary button: it sends a single press, like a doorbell or a garage-door impulse. It does not stay ON.

At a glance: name, icon, and one round press button.

Controls:

ControlWhat it does
Press buttonSends one impulse. The button lights briefly while the press is sent.

Sub-types (chosen by your installer):

  • ON — every press sends ON.
  • OFF — every press sends OFF.
  • Toggle — each press flips the device to the opposite state.

No detail page.

Frequently Asked Questions

How is a push button different from a switch?

A push button sends a momentary command and does not stay on. Its configured sub-type sends ON, OFF or Toggle.

Does switching a dimmer off erase its brightness level?

No. On/off controls preserve the stored level, and switching on returns to the last level.

How do I set a dimmer precisely?

Open its detail page for a brightness slider, 5% minus/plus steps and presets at 25%, 50%, 75% and 100%.

How do I change an RGB light’s color?

Tap a color swatch for quick selection or open the detail page to use the color wheel, favorites and white shades.

Can tunable-white lights change warmth as well as brightness?

Yes. Their detail page provides brightness and color-temperature controls with warm, neutral and cool presets.
