I can’t figure out how to make a HUE light blue … this is code that works for red:

```auto
let devices = await Homey.devices.getDevices();
_.forEach(devices, device => {
    if(!device.capabilities.includes("light_hue")) return;
    device.setCapabilityValue('light_hue', 1);
    device.setCapabilityValue('light_saturation', 1);
    device.setCapabilityValue('light_temperature', 2);
    device.setCapabilityValue('light_mode', 'null');
});

```

Any idea how to set it to blue?

its a normalized value between 0 and 1. So red 360 becomes 360/360 = 1. Blue becomes 240/360 = 0.66.
