Description
Hello there! Thank you for this library; it has been immensely useful in automating my smart home full of mostly TPLink devices.
I am having an issue simply querying and printing several of a bulb's properties using the current version of python-kasa. I checked the documentation and my code seems to be in line with the examples.
I'm running this code in a clean VM with only python-kasa installed using sudo pip3 install python-kasa
Ubuntu 20.04.3 LTS
Python 3.8.10
kasa, version 0.4.0
Code:
#!/usr/bin/env python3
import os
import time
import asyncio
from kasa import SmartBulb
bulb = SmartBulb('10.10.10.123')
count = 0
while True:
count = count + 1
asyncio.run(bulb.update())
os.system('clear')
print ('\n\n')
print (f'\tCount: {count}\n')
print (f'\tPower: {"On" if bulb.is_on else "Off"}')
print (f'\tHue: {bulb.hsv[0]}')
print (f'\tSat: {bulb.hsv[1]}')
print (f'\tVol: {bulb.hsv[2]}')
print (f'\tTemp: {bulb.color_temp}')
time.sleep(1)
Error message:

On a side note, when I install(ed) python-kasa, there is an error with requests and idna:
sudo pip3 install python-kasa --force-reinstall
ERROR: requests 2.25.1 has requirement idna<3,>=2.5, but you'll have idna 3.2 which is incompatible.
Also, on my "prod" machine, I use the code from PR-117 installed and this code functions without issue, although a lot of newer HW versioned switches don't show up (out of scope).
