Look like linting is failing, I will try to correct it.

Also the linting errors need to be addressed. Otherwise it looks good to me. I'd appreciate a review from @rytilahti as I haven't looked into the HS300 code.

kasa/smartstrip.py
emeter_rt[field] += value

# Voltage is averaged
emeter_rt['voltage_mv'] /= count

I get the idea here, but have you ever noticed the individual plugs reporting different voltage? Normally you should get the same voltage from each child-plug.

kasa/smartstrip.py
emeter_rt: DefaultDict[int, float] = defaultdict(lambda: 0.0)
count = 0
for plug in self.children:
if not plug.has_emeter:

Is this a real-world case, where some sockets on the same strip have and some sockets don't have emeter? If not I think this would be redundant

Testing with changes:

import asyncio
from kasa import SmartStrip
strip = SmartStrip("172.25.100.114")
asyncio.run(strip.update())

print(strip.alias)

for plug in strip.children:
   print(f"{plug.alias}: {plug.emeter_realtime}")

Output shows same data for each plug, unlike the app.

I am guessing this isn't the expected behavior?

Just wanted to say that it would be great to see kasa officially support tplink powerstrips with emeters. I don't have mine yet, but from the looks of the last comment, it's not reporting real time data correctly.

Last I checked it didn't report any emeter data.

Looks like the PR has gone stale, so you'd need to manually add the changes from the PR to your local codebase to test it. Unfortunately we don't have the device at all in Europe, so people who have the device (I think it's available only in the US) should provide at minimum a json dump and do the real-world testing.

Superseded by #203, thanks for the PR though :-)
