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:

Get Device Power Status Using Device Properties

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

PropertyTypeDescription

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

properties.battery.level

Number (0-1)

Battery level of the device as a decimal value between 0 and 1, inclusive

properties.battery.status

Enum (string)

Current status of the battery charge level.

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.

Request:

device = seam.devices.get("36cf1a96-196d-41b0-9804-88154387f1f9")
if device.properties.has_direct_power == True:
  pprint("Power Source: Wired")
else:
  pprint("Power Source: Battery-powered")
  pprint("Battery Level: " + str(device.properties.battery.level))
  pprint("Battery Status: " + device.properties.battery.status)

Response:

'Power Source: Battery-powered'
'Battery Level: 0.9999532347993827'
'Battery Status: full'

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.

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:

ParameterTypeDescription

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:

Request:

device_battery_status_changed_events = seam.events.list(
    device_id = "36cf1a96-196d-41b0-9804-88154387f1f9",
    event_type = "device.battery_status_changed",
    since = "2024-01-01T00:00:00Z"
)
pprint(device_battery_status_changed_events)

Response:

[{'connected_account_id': 'c1413928-f527-4e12-abf9-d5e18d92dd33',
  'created_at': '2024-01-01T02:25:10.158Z',
  'device_id': '36cf1a96-196d-41b0-9804-88154387f1f9',
  'event_id': 'de4314a2-903d-53e9-bb5e-ded5d19ad074',
  'event_type': 'device.battery_status_changed',
  'occurred_at': '2024-01-01T02:25:10.158Z',
  'workspace_id': '398d80b7-3f96-47c2-b85a-6f8ba21d07be'}]

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.
