Nursery Monitoring

Pre-requisite: The user has to be signed in to perform the following operations.

What a Baby camera watches beyond motion: crying, and — on cameras with sensors — the temperature and humidity of the room. Plus the night lamp. Sensor features are advertised through clusters; check device.hasTemperatureSensor() / hasHumiditySensor() / supportsNightLamp() before showing a control.

Cry Detection

Crying is an AI detection like person or vehicle. Switch it with the cry flag of AiDetection (under cloudAi or edgeAi on AiSettingsRequest — cameras that detect on-device advertise DeviceCluster.supportsEdgeAICry()), and mute its notifications with cryMute:

InstaVision.deviceServices.updateAiSettings(
  device = device,
  request = AiSettingsRequest(cloudAi = AiDetection(cry = true)),
  onSuccess = { }, onError = { error -> }
)
InstaVision.deviceServices.updateNotificationSettings(
  device = device,
  request = Notification(cryMute = false),
  onSuccess = { }, onError = { error -> }
)

A detection arrives as an event tagged EventTag.CRY.

Temperature and Humidity Alerts

Two clusters, each with an on/off switch and a high and low threshold:

Cluster (`DeviceClusterTypes`)	Attributes (`ClusterAttributeTypes`)	`DeviceCluster` helpers
`TemperatureSettings` (`0xFC23`)	`TemperatureAlertEnabled`, `HighTemperatureThreshold`, `LowTemperatureThreshold`	`supportsTemperatureAlert()`, `isTemperatureAlertEnabled()`, `highTemperatureThreshold()`, `lowTemperatureThreshold()`
`HumiditySettings` (`0xFC24`)	`HumidityAlertEnabled`, `HighHumidityThreshold`, `LowHumidityThreshold`	`supportsHumidityAlert()`, `isHumidityAlertEnabled()`, `highHumidityThreshold()`, `lowHumidityThreshold()`

Write thresholds with updateCluster (several attributes at once) or updateClusterAttribute — see Device Clusters. Crossing a threshold raises an event tagged HIGH_TEMPERATURE / LOW_TEMPERATURE / HIGH_HUMIDITY / LOW_HUMIDITY with the reading in event.sensorReading; temperatureMute / humidityMute silence the notifications.

While a live view is running the camera also pushes readings over the stream:

viewModelScope.launch {
  client.temperatureInfo.collectLatest { temperature -> /* Float?; null until the first reading */ }
}
viewModelScope.launch {
  client.humidityInfo.collectLatest { humidity -> /* Float?; null until the first non-zero reading */ }
}

The display unit is a space setting: Space.settings?.temperatureUnit holds TemperatureUnit.value ("C" / "F", default "F").

Night Lamp

The NightLampSettings cluster (0xFC25) has two attributes, NightLampEnabled and NightLampBrightness. DeviceCluster.isNightLampEnabled() reads the switch and nightLampInfo() returns a ClusterValueProperty with the brightness value and its min / max / step. Write them with the cluster APIs above.
