Description

LitBomb
opened on Jan 28, 2022

I am running:

  • Python 3.10.2
  • Python-kasa version 0.4.1
  • inside PowerShell 5.1.19041.1320 on Windows 10
  • Kasa Bulb KL135 firmware version 1.0.10

Every time I call:
kasa --type bulb --host <blubIP> hsv 0 100 100

I get the following exception. The bulb does turn to red though. Am I missing something? I also get other errors running kasa discovery. Thanks.

Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x0000015646DAE8C0>

    Looks like windows specific issue of event loop not being closed automatically, needs more investigation to figure out what's the best approach to fix this.

    Forget that, it looks like the event loop is closed already and something tries to close it again. @LitBomb is that all output you are getting? There is no code lines in that traceback from this library, so I'm wondering what is happening..

    @rytilahti Yes, that is all I get from the PowerShell console output when I run the bulb color command. I also get errors doing discovery. See below. I want to mention that I have two HS300 power strips (firmware version 1.0.21) and five KP115 plugs (firmware version 1.0.18) and a KL135 blub (firmware version 1.0.10).

    Please let me know if I can get you more debug output. Thanks for looking into this.

    I am also seeing this error using discover.

    Python code (from https://python-kasa.readthedocs.io/en/latest/discover.html):

    import asyncio
from kasa import Discover

devices = asyncio.run(Discover.discover())
for addr, dev in devices.items():
    asyncio.run(dev.update())
    print(f"{addr} >> {dev}")

    Output:
