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)[source]

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.

children: List['SmartDevice']
async current_consumption() → float[source]

Get the current power consumption in watts.

Return the device type.

property emeter_realtime: kasa.emeterstatus.EmeterStatus

Return current energy readings.

property emeter_this_month: Optional[float]

Return this month’s energy consumption in kWh.

property emeter_today: Optional[float]

Return this month’s energy consumption in kWh.

emeter_type = 'emeter'
async erase_emeter_stats()[source]

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[source]

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[source]

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() → kasa.emeterstatus.EmeterStatus[source]

Retrieve current energy readings.

get_plug_by_index(index: int) → kasa.smartdevice.SmartDevice

Return child device for the given index.

get_plug_by_name(name: str) → kasa.smartdevice.SmartDevice

Return child device for the given name.

async get_sys_info() → Dict[str, Any]

Retrieve system information.

async get_time() → Optional[datetime.datetime]

Return current time from the device, if available.

async get_timezone() → Dict

Return timezone information.

property has_emeter: bool

Return True if device has an energy meter.

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 the device is dimmable.

property is_dimmer: bool

Return True if the device is a dimmer.

property is_light_strip: bool

Return True if the device is a led strip.

property is_off: 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

Return True if the device supports color temperature.

property led: bool

Return the state of the led.

property location: Dict

Return geographical location.

property mac: str

Return mac address.

Returns

mac address in hexadecimal with colons, e.g. 01:23:45:67:89:ab

property model: str

Return device model.

modules: Dict[str, Any]
property on_since: Optional[datetime.datetime]

Return the maximum on-time of all outlets.

async reboot(delay: int = 1) → None

Reboot the device.

Note that giving a delay of zero causes this to block, as the device reboots immediately without responding to the call.

property rssi: Optional[int]

Return WiFi signal strength (rssi).

async set_alias(alias: str) → None

Set the device name (alias).

async set_led(state: bool)[source]

Set the state of the led (night mode).

async set_mac(mac)

Set the mac address.

Parameters

mac (str) – mac in hexadecimal with colons, e.g. 01:23:45:67:89:ab

property state_information: Dict[str, Any]

Return strip-specific state information.

Returns

Strip information dict, keys in user-presentable form.

property supported_modules: List[str]

Return a set of modules supported by the device.

async turn_off(**kwargs)[source]

Turn the strip off.

async turn_on(**kwargs)[source]
