José Antonio Jiménez Campos edited this page May 19, 2023 · 26 revisions

Stateless buttons can be used to trigger state changes in HomeKit based on the type of press placed on the button.

Type Service Type
3 Stateless Button
13 Stateless Button + Doorbell

The following configuration is available for stateless buttons and doorbells:

Section Key Description
Actions "0", "1" etc. The actions performed by the service
Initial Lock State "ks" Lock state at boot
State & Status Inputs "f[n]" & "g[n]" Inputs that manage service state
Service Notifications "m" Notifications to send to another service
Historical Data Characteristics

Doorbell service works like a stateless button, and it sends a notification when single press type is triggered. All Stateless Button functions will work too.

Example

{
  "c": {
    "io": [ [ [ 0 ], 6 ] ],
    "b": [ [ 0, 5 ] ]
  },
  "a": [{
    "t": 3,
    "f0": [ [ 0, 1 ] ],
    "f1": [ [ 0, 2 ] ],
    "f2": [ [ 0, 3 ] ]
  }]
}

This is an example of a stateless button ("t": 3) connected to GPIO 0 with 3 state inputs defined; single press (1), double press (2) & long press (3)
