Pan/Tilt/Zoom Button

This script creates a button that can pan, tilt, or zoom a PTZ camera. This button can then be synced to platforms like HomeKit, which do not natively support PTZ commands.

class PTZButton extends ScryptedDeviceBase implements OnOff, Settings {
    timeout: any;

    constructor(nativeId: string) {
        super(nativeId);
        // make this device a switch so it can be synced.
        setTimeout(() => {
            systemManager.getDeviceById(this.id).setType(ScryptedDeviceType.Switch);
        });
    }

    async turnOn() {
        this.on = true;
        clearTimeout(this.timeout);
        // reset the switch after a second so you can press it again!
        this.timeout = setTimeout(() => this.on = false, 1000);

        const ptzCamera = systemManager.getDeviceById<PanTiltZoom>(this.storage.getItem('ptzCamera'));

        // when the button is pressed, spin 90 degrees.
        // range is between -1 (-180 degrees) and 1 (180 degrees)
        await ptzCamera.ptzCommand({
            [this.storage.getItem('command') || 'pan']: parseFloat(this.storage.getItem('distance')) || .5,
        });
    }

    async turnOff() {
        this.on = false;
    }

    async getSettings(): Promise<Setting[]> {
