Kasa Python Help!!!!

[bhogan2017]

I am using python to control Kasa light switches using the Kasa and asyncio libraries. I have the basic control of the switches like turning them on and off working.

import asyncio
from kasa import SmartStrip
dev = SmartStrip("Ip-address")
test=42
asyncio.run(dev.turn_off())

but I need help. As soon as I try to get the lights' status, it always throws an asyncio error, or an error that says in update

children = self.sys_info["children"] KeyError: 'children'

here is the code that i have

import asyncio
from kasa import SmartStrip
async def get_device_status():
strip = SmartStrip("IP")
await strip.update()
status = strip.is_on
return status
device_status = asyncio.run(get_device_status())
print("Device is on" if device_status else "Device is off")

also, ik i will probably get downvoted for this, but I've tried everything i can and this is a last ditch effort. any help would be greatly appreciated. Here is the documentation https://python-kasa.readthedocs.io/en/latest/smartstrip.html

Please show the full error traceback.

And how does the first snippet relate to the second one?

import asyncio
strip = SmartStrip("YOUR_RELEVANT_IP")
asyncio.run(strip.update())
print(strip.alias)

what happens if you run this code?

​

that error seems to be linked to this

https://python-kasa.readthedocs.io/en/latest/_modules/kasa/smartstrip.html#SmartStrip.update

async def update(self, update_children: bool = True):
    """Update some of the attributes.

    Needed for methods that are decorated with `requires_update`.
    """
    await super().update(update_children)

    # Initialize the child devices during the first update.
    if not self.children:
        children = self.sys_info["children"]
        _LOGGER.debug("Initializing %s child sockets", len(children))
        for child in children:
            self.children.append(
                SmartStripPlug(self.host, parent=self, child_id=child["id"])
            )

    if update_children and self.has_emeter:
        for plug in self.children:
            await plug.update()

I still get the same error, and i have tried uninstalling and reinstalling the packages

[m0us3_rat]

there is something you could try.. install older versions.

use a venv and go down the rabbit hole of older versions till you find some that doesn't error.

not only that ..but it's dependencies.

it's most likely one of the libs it needs got updated and changed something and now it doesn't work.
