Displaying Device Power Status

You can display the power status of your end users' devices in your app.

You can display the power status of your end users' devices in your app, including whether the device is wired or battery-powered. Further, for battery-powered devices, you can also display information about the battery status, such as the battery charge level and the battery status.

To display this information, use either of the following Seam mechanisms:

• Use the properties.has_direct_power, and properties.battery properties of the device object.

• Use the device.low_battery and device.battery_status_changed events.

Get Device Power Status Using Device Properties

Seam polls connected devices and accounts every ten minutes and updates the following device properties accordingly:

Property	Type	Description
properties.has_direct_power	Boolean	Indicates whether the device has direct power, that is, whether the device is wired
properties.battery	Object	Battery information, including level and status If the device is offline, Seam does not return this property.
properties.battery.level	Number (0-1)	Battery level of the device as a decimal value between 0 and 1, inclusive If the device is offline, Seam does not return this property.
properties.battery.status	Enum (string)	Current status of the battery charge level. If the device is offline, Seam does not return this property. Values are: critical: Indicates an extremely low level, suggesting imminent shutdown or an urgent need for charging. low: Signifies that the battery is under the preferred threshold and should be charged soon. good: Denotes a satisfactory charge level, adequate for normal use without the immediate need for recharging. full: Represents a battery that is fully charged, providing the maximum duration of usage.

Use a Get Device request to retrieve the current power status of a device. First, determine whether the device is wired. If the device is battery-powered (that is, not wired), get the battery level and status. Then, display the retrieved device power status in your app.

You can also use the prebuilt device details Seam Component, which includes a device power status display.

Get Device Power Status Using Battery-Related Events

Seam generates the following battery-related events:

• device.low_battery

• device.battery_status_changed

You can retrieve these events using a List Events request or through webhooks and then display the corresponding status in your app.

Get Battery-Related Events Using a List Events Request

When issuing a List Events request to retrieve device.low_battery or device.battery_status_changed events for a specific device, include the following parameters:

Parameter	Type	Description
device_id	String (UUID)	ID of the device for which you want to retrieve device.connected or device.disconnected events
event_type	String	Event type that you want to retrieve, that is, device.connected or device.disconnected
since	String	Desired starting event generation date and time You must include since or between.
between	Set of two strings	Desired starting and ending event generation dates and times For example: ["2024-01-01T00:00:00Z", "2024-02-01T00:00:00Z"] You must include between or since.

The following example uses the List Events request to retrieve all device.battery_status_changed events for a specific device since January 1, 2024:

Retrieve Battery-Related Events Using a Webhook

You can set up webhook endpoints to receive device.battery_status_changed and device.low_battery events. Then, you can use the receipt of these events to display the corresponding device status in your app. For more information about configuring webhooks, see Webhooks.
