Description
I'm relatively new to asyncio sooo maybe I use it in a wrong way.
Therefore maybe I call the methods wrongly.
My first goal was to just turn off an on the light and waiting 1 seconds in between those actions.
It works for the first bulb.set_brightness(0) call.
When I call bulb.set_brightness(100) it will set the brightness of my LB130 light bulb indeed to 100.
However the responds of the device raises a SmartDeviceException.
This is my current code:
from kasa import SmartBulb
import asyncio
import time
IP = "192.168.179.54"
bulb = SmartBulb(IP)
asyncio.run(bulb.update())
for i in range(10):
asyncio.run(bulb.set_brightness(0))
time.sleep(1)
asyncio.run(bulb.set_brightness(100))
time.sleep(1)The entire console output:

The above exception was the direct cause of the following exception:

raise SmartDeviceException(f"Communication error on {target}:{cmd}") from ex
kasa.exceptions.SmartDeviceException: Communication error on smartlife.iot.smartbulb.lightingservice:transition_light_state
Therefore the error gets thrown in the _query_helper function from the smartdevice.py module:
As mentioned above during the call of the brightness method I receive a responds that is perfectly fine.
However the second responds does not come through and raises the exception.

request = self._create_request(target, cmd, arg, child_ids)

response = await self.protocol.query(request=request)
