Hello,
i would like to read watt's from my zigbee socket so i make a script like for my weather sensors:

#!/usr/bin/env python3
import sys, os

from miio import Gateway
gateway = Gateway("192.xxxxx", "token")
gateway.discover_devices()
devices = gateway.devices
plugzigbee = devices["lumi.4cf8cdf3c7e54c7"]
plugzigbee.update()
#print(plugzigbee.status)
print(plugzigbee.status["load_power"])

but it throws an error on plugzigbee.update():

Traceback (most recent call last):
  File "/etc/zabbix/scripts/./socket_zig.py", line 18, in <module>
    plugzigbee.update()
  File "/usr/local/lib/python3.10/site-packages/miio/click_common.py", line 179, in _wrap
    return func(self, *args, **kwargs)
  File "/usr/local/lib/python3.10/site-packages/miio/gateway/devices/subdevice.py", line 119, in update
    values = self.get_property_exp(list(self.get_prop_exp_dict.keys()))
  File "/usr/local/lib/python3.10/site-packages/miio/click_common.py", line 179, in _wrap
    return func(self, *args, **kwargs)
  File "/usr/local/lib/python3.10/site-packages/miio/gateway/devices/subdevice.py", line 191, in get_property_exp
    raise GatewayException(
miio.gateway.gateway.GatewayException: unexpected result while fetching properties ['neutral_0', 'load_power']: [50.7] on model ZNCZ04LM

but the load power is fetched, in this case 50.7 watts ;)
any advices?

The PR to fix the issue is here: #1449
However that requires a new version of python miio to be released.

In the mean time you can use the following command to get the status and load power:

from miio import Gateway
gateway = Gateway("192.xxxxx", "token")
gateway.discover_devices()
devices = gateway.devices
plugzigbee = devices["lumi.4cf8cdf3c7e54c7"]
print(plugzigbee.get_property_exp(["load_power"]))
print(plugzigbee.get_property_exp(["channel_0"]))

I think the unexpected result comes as it is requesting two properties and just getting one back. Maybe @starkillerOG knows what's the solution here :-)

@exeq89 rytilahti is right, we are requesting both the status (on/off) and the load power and only getting the load_power back.
That is causing the issue.

It is a simple fix, we just need to figure out the correct name of the status property.

Could you try the following script:

from miio import Gateway
gateway = Gateway("192.xxxxx", "token")
gateway.discover_devices()
devices = gateway.devices
plugzigbee = devices["lumi.4cf8cdf3c7e54c7"]
print(plugzigbee.get_property_exp(["neutral_0"]))
print(plugzigbee.get_property_exp(["channel_0"]))
print(plugzigbee.get_property_exp(["status"]))
print(plugzigbee.get_property_exp(["power_status"]))

These are my best guess for what the correct name of the status property is.
If none of these work, we will have to sniff the trafic from the mi home app to figure out the correct name.

Comment out the ones that do not work, to prevent the script stopping on the first error.

Hello
only one command worked: print(plugzigbee.get_property_exp(["channel_0"]))
i run commands in python and the output is:

greath that is all that is needed, channel_0 is the correct property, I will make a PR to fix it.
