Function: useSwitch()

useSwitch(device, name, element): boolean | undefined

Subscribe to one switch, as a boolean. See useNumber.

Boolean rather than the "On"/"Off" token because that is what a checkbox or a toggle wants; undefined still distinguishes "not there" from "off".

Parameters

device

string

The device name.

name

string

The property name.

element

string

The element name.

Returns

boolean | undefined

Whether the switch is On, or undefined when absent or of another kind.
