Smart strips

Note

Feel free to open a pull request to improve the documentation!

Command-line usage

To command a single socket of a strip, you will need to specify it either by using --index or by using --name. If not specified, the commands will act on the parent device: turning the strip off will turn off all sockets.

Example: Turn on the first socket (the indexing starts from zero):

$ kasa --type strip --host <host> on --index 0

Example: Turn off the socket by name:

$ kasa --type strip --host <host> off --name "Maybe Kitchen"

API documentation

class kasa.SmartStrip(host: str, *, config: Optional[DeviceConfig] = None, protocol: Optional[BaseProtocol] = None)

Representation of a TP-Link Smart Power Strip.

A strip consists of the parent device and its children. All methods of the parent act on all children, while the child devices share the common API with the SmartPlug class.

To initialize, you have to await update() at least once. This will allow accessing the properties using the exposed properties.

All changes to the device are done using awaitable methods, which will not change the cached values, but you must await update() separately.

Errors reported by the device are raised as SmartDeviceExceptions, and should be handled by the user of the library.

Examples:

>>> import asyncio
>>> strip = SmartStrip("127.0.0.1")
>>> asyncio.run(strip.update())
>>> strip.alias
TP-LINK_Power Strip_CF69

All methods act on the whole strip:

>>> for plug in strip.children:
>>>    print(f"{plug.alias}: {plug.is_on}")
Plug 1: True
Plug 2: False
Plug 3: False
>>> strip.is_on
True
>>> asyncio.run(strip.turn_off())

Accessing individual plugs can be done using the children property:

>>> len(strip.children)
3
>>> for plug in strip.children:
>>>    print(f"{plug.alias}: {plug.is_on}")
Plug 1: False
Plug 2: False
Plug 3: False
>>> asyncio.run(strip.children[1].turn_on())
>>> asyncio.run(strip.update())
>>> strip.is_on
True

For more examples, see the SmartDevice class.

add_module(name: str, module: Module)

Register a module.

property alias: Optional[str]

Return device name (alias).

children: List['SmartDevice']

property config: DeviceConfig

Return the device configuration.

async static connect(*, host: Optional[str] = None, config: Optional[DeviceConfig] = None) → SmartDevice

Connect to a single device by the given hostname or device configuration.

This method avoids the UDP based discovery process and will connect directly to the device.

It is generally preferred to avoid discover_single() and use this function instead as it should perform better when the WiFi network is congested or the device is not responding to discovery requests.

Parameters:

• host – Hostname of device to query

• config – Connection parameters to ensure the correct protocol and connection options are used.

Return type:

SmartDevice

Returns:

Object for querying/controlling found device.

property credentials: Optional[Credentials]

property credentials_hash: Optional[str]

The protocol specific hash of the credentials the device is using.

async current_consumption() → float

Get the current power consumption in watts.

property device_id: str

Return unique ID for the device.

If not overridden, this is the MAC address of the device. Individual sockets on strips will override this.

property device_type: DeviceType

Return the device type.

async disconnect()

Disconnect and close any underlying connection resources.

property emeter_realtime: EmeterStatus

Return current energy readings.

property emeter_this_month: Optional[float]

Erase energy meter statistics for all plugs.

property features: Set[str]

Return a set of features that the device supports.

async get_emeter_daily(year: Optional[int] = None, month: Optional[int] = None, kwh: bool = True) → Dict

Retrieve daily statistics for a given month.

Parameters:

• year – year for which to retrieve statistics (default: this year)

• month – month for which to retrieve statistics (default: this month)

• kwh – return usage in kWh (default: True)

Returns:

mapping of day of month to value

async get_emeter_monthly(year: Optional[int] = None, kwh: bool = True) → Dict

Retrieve monthly statistics for a given year.

Parameters:

• year – year for which to retrieve statistics (default: this year)

• kwh – return usage in kWh (default: True)

async get_emeter_realtime() → EmeterStatus

Retrieve current energy readings.

get_plug_by_index(index: int) → SmartDevice

Return child device for the given index.

get_plug_by_name(name: str) → SmartDevice

Return child device for the given name.

async get_sys_info() → Dict[str, Any]

Retrieve system information.

async get_time() → Optional[datetime]

Return current time from the device, if available.

async get_timezone() → Dict

Return timezone information.

property has_children: bool

Return true if the device has children devices.

property has_emeter: bool

Return True if device has an energy meter.

property host: str

The device host.

property hw_info: Dict

Return hardware information.

This returns just a selection of sysinfo keys that are related to hardware.

property internal_state: Any

Return the internal state of the instance.

The returned object contains the raw results from the last update call. This should only be used for debugging purposes.

property is_bulb: bool

Return True if the device is a bulb.

property is_color: bool

Return True if the device supports color changes.

property is_dimmable: bool

Return True if device is off.

property is_on: bool

Return if any of the outlets are on.

property is_plug: bool

Return True if the device is a plug.

property is_strip: bool

Return True if the device is a strip.

property is_strip_socket: bool

Return True if the device is a strip socket.

property is_variable_color_temp: bool
