Class: SirenControl<TStorage> ​

Defined in: sensor/siren.ts:52

Siren control sensor. Override setActive()/setInactive() to drive your hardware, then await super.setActive() / await super.setInactive() to sync the SDK state. For hardware-pushed updates, call the super methods from your event handler. That bypasses any plugin override and only syncs state.

Methods ​

getValue() ​

Call Signature ​

getValue<K>(property): SirenControlProperties[K] | undefined

Defined in: sensor/base.ts:345

Get the current value of a sensor property. Calling the generic overload with a property enum value gives a properly typed result.

Type Parameters ​
K ​

K extends keyof SirenControlProperties

Parameters ​
property ​

K

Returns ​

SirenControlProperties[K] | undefined

Inherited from ​

Sensor.getValue

Call Signature ​

getValue(property): unknown

Defined in: sensor/base.ts:346

Get the current value of a sensor property. Calling the generic overload with a property enum value gives a properly typed result.

Parameters ​
property ​

string

Returns ​

unknown

Inherited from ​

Sensor.getValue

getValues() ​

getValues(): Readonly<TProperties>

Defined in: sensor/base.ts:362

Get a read-only snapshot of all property values.

Returns ​

Readonly<TProperties>

Shallow copy of every property currently held by the sensor.

Example ​

ts
const snapshot = sensor.getValues();
console.log(snapshot);

Inherited from ​

Sensor.getValues

hasCapability() ​

hasCapability(capability): boolean

Defined in: sensor/base.ts:388

Check whether the sensor advertises a capability.

Parameters ​

capability ​

string

Capability flag to look for.

Returns ​

boolean

True if the sensor currently advertises it.

Example ​

ts
const dimmable = sensor.hasCapability('brightness');

Inherited from ​

Sensor.hasCapability

onStart() ​

protected onStart(): void | Promise<void>

Defined in: sensor/base.ts:651

Lifecycle hook, called once the sensor is registered and live (storage and RPC are wired up). Override it to start work whose lifetime matches the sensor's: polling loops, event subscriptions, timers.

Errors thrown here are swallowed, not logged. Handle failures inside the override. Paired 1:1 with onStop, which runs on removal, plugin shutdown or cleanup.

Returns ​

void | Promise<void>

Example ​

ts
protected override onStart(): void {
  this._timer = setInterval(() => this.poll(), 5_000);
}

Inherited from ​

Sensor.onStart

onStop() ​

protected onStop(): void | Promise<void>

Defined in: sensor/base.ts:664

Counterpart of onStart: tear down whatever it started, such as timers, subscriptions and external resources.

Returns ​

void | Promise<void>

Example ​

ts
protected override onStop(): void {
  if (this._timer) clearInterval(this._timer);
}

Inherited from ​

Sensor.onStop

setActive() ​

setActive(): Promise<void>

Defined in: sensor/siren.ts:82

Activate the siren. Override to drive hardware and call await super.setActive() after success to sync the SDK state.

Returns ​

Promise<void>

Example ​

ts
await siren.setActive();

setDisplayName() ​

setDisplayName(value): void

Defined in: sensor/base.ts:337

Set the display name (the only mutable identifier on a sensor).

Parameters ​

value ​

string

Human-readable label shown in the UI.

Returns ​

void

Example ​

ts
sensor.setDisplayName('Front Door Motion');

Inherited from ​

Sensor.setDisplayName

setInactive() ​

setInactive(): Promise<void>

Defined in: sensor/siren.ts:95

Deactivate the siren. Override to drive hardware and call await super.setInactive() after success to sync the SDK state.

Returns ​

Promise<void>

Example ​

ts
await siren.setInactive();

setVolume() ​

setVolume(value): Promise<void>

Defined in: sensor/siren.ts:110

Set volume. Override to drive hardware and call await super.setVolume(value) after success. The default implementation clamps the value to [0, 100].

Parameters ​

value ​

number

Volume level in the range 0-100.

Returns ​

Promise<void>

Example ​

ts
await siren.setVolume(80);

updateModelSpec() ​

updateModelSpec(): void

Defined in: sensor/base.ts:565

Re-announces the model spec, e.g. once the models finished loading.

The spec a detector reports at registration is what it knows at that moment: models that load in the background are missing from it. Call this after loading, the server replaces its copy.

Returns ​

void

Example ​

typescript
async onStart(): Promise<void> {
  await this.loadModel();
  this.updateModelSpec();
}

Inherited from ​

Sensor.updateModelSpec
