Expose reboot through the feature interface. This can be useful in situations where one wants to reboot the device, e.g., in recent cases where frequent update calls will render the device unresponsive after a specific amount of time.

|
|
|
|
You don't usually want to initialize this class manually,
|
|
but either use :class:`Discover` class, or use one of the subclasses:
|
|
|
|
* :class:`IotPlug`
|
|
* :class:`IotBulb`
|
|
* :class:`IotStrip`
|
|
* :class:`IotDimmer`
|
|
* :class:`IotLightStrip`
|
|
|
|
To initialize, you have to await :func:`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
|
|
:class:`KasaException <kasa.exceptions.KasaException>`,
|
|
and should be handled by the user of the library.
|
|
|
|
Examples:
|
|
>>> import asyncio
|
|
>>> dev = IotDevice("127.0.0.1")
|
|
>>> asyncio.run(dev.update())
|
|
|
|
All devices provide several informational properties:
|
|
|
|
>>> dev.alias
|
|
Bedroom Lamp Plug
|
|
>>> dev.model
|
|
HS110(EU)
|
|
>>> dev.rssi
|
|
-71
|
|
>>> dev.mac
|
|
50:C7:BF:00:00:00
|
|
|
|
Some information can also be changed programmatically:
|
|
|
|
>>> asyncio.run(dev.set_alias("new alias"))
|
|
>>> asyncio.run(dev.set_mac("01:23:45:67:89:ab"))
|
|
>>> asyncio.run(dev.update())
|
|
>>> dev.alias
|
|
new alias
|
|
>>> dev.mac
|
|
01:23:45:67:89:ab
|
|
|
|
When initialized using discovery or using a subclass,
|
|
you can check the type of the device:
|
|
|
|
>>> dev.is_bulb
|
|
False
|
|
>>> dev.is_strip
|
|
False
|
|
>>> dev.is_plug
|
|
True
|
|
|
|
You can also get the hardware and software as a dict,
|
|
or access the full device response:
|
|
|
|
>>> dev.hw_info
|
|
{'sw_ver': '1.2.5 Build 171213 Rel.101523',
|
|
'hw_ver': '1.0',
|
|
'mac': '01:23:45:67:89:ab',
|
|
'type': 'IOT.SMARTPLUGSWITCH',
|
|
'hwId': '00000000000000000000000000000000',
|
|
'fwId': '00000000000000000000000000000000',
|
|
'oemId': '00000000000000000000000000000000',
|
|
'dev_name': 'Wi-Fi Smart Plug With Energy Monitoring'}
|
|
>>> dev.sys_info
|
|
|
|
All devices can be turned on and off:
|
|
|
|
>>> asyncio.run(dev.turn_off())
|
|
>>> asyncio.run(dev.turn_on())
|
|
>>> asyncio.run(dev.update())
|
|
>>> dev.is_on
|
|
True
|
|
|
|
Some devices provide energy consumption meter,
|
|
and regular update will already fetch some information:
|
|
|
|
>>> dev.has_emeter
|
|
True
|
|
>>> dev.emeter_realtime
|
|
<EmeterStatus power=0.928511 voltage=231.067823 current=0.014937 total=55.139>
|
|
>>> dev.emeter_today
|
|
>>> dev.emeter_this_month
|
|
|
|
You can also query the historical data (note that these needs to be awaited),
|
|
keyed with month/day:
|
|
|
|
>>> asyncio.run(dev.get_emeter_monthly(year=2016))
|
|
{11: 1.089, 12: 1.582}
|
|
>>> asyncio.run(dev.get_emeter_daily(year=2016, month=11))
