So… painfully… I am still struggling…
I have managed to run su - homeassistant. which changes the user to homeassistant@hassbian:
As pi@hassbian or homeassistant@hassbian when I run source svr/homeassistant/bin/activate it returns:
-su: /svr/homeassistant/bin/activate: No such file or directory
EDIT:
Please see the below
Apologies, I am a complete and utter n00b. I have finally got it all up and running and am so very happy! If anyone runs into the same trouble and wants a hand feel free to msg me!
Thanks for all of the help!!
Has anyone ever managed to get around the original issue of having more than one plug running?
Congratulations! I can see on your screenshot you wasn’t inside of the python-virtualenv. 
I don’t know much about python, home assistant and I cannot test the suggestion on my own. Nevertheless:
https://github.com/xavV/xiaomi/blob/master/xiaomi/protocol.py
I suspect the “@staticmethod” annotation of the method key_iv(). Can you remove all the @staticmethod annotations of the file and restart home assistant? In the best case the checksum error will be gone. Please report! 
Hi, apologies I have only just had a chance to test! (I am based in New Zealand) Thank you so much for your help and trying to get this working!! I replaced the protocol.py located in homeassistant/xiaomi with your version the result was:
2017-07-13 20:45:27 ERROR (Thread-1) [homeassistant.util.yaml] while scanning for the next token
found character '\t' that cannot start any token
in "/home/homeassistant/.homeassistant/configuration.yaml", line 101, column 44
2017-07-13 20:45:27 ERROR (MainThread) [homeassistant.bootstrap] Error loading /home/homeassistant/.homeassistant/configuration.yaml: while scanning for the next token
found character '\t' that cannot start any token
in "/home/homeassistant/.homeassistant/configuration.yaml", line 101, column 44
It works fine without the additional switches in the yaml. But as soon as I add the following below the working switch:
- platform: xiaomiplug
host: xx.xx.xxx.xxx
name: Spare Plug
token: {token redacted}
- platform: xiaomiplug
host: xx.xx.xxx.xxx
name: Lounge Lamp
token: {token redacted}
Then its back to error logs and having to sudo reboot out of PuTTY.
Can you try again by removing the complete line? You left the tab in front of the annotation. You are safe if you remove the linebreak also. I hope your configuration.yaml is indented properly:
- platform: xiaomiplug
host: xx.xx.xxx.xxx
name: Spare Plug
token: {token redacted}
- platform: xiaomiplug
host: xx.xx.xxx.xxx
name: Lounge Lamp
token: {token redacted}
For clarification: https://gist.github.com/syssi/4da06e2c2d1e897984b0c53778cc4da4
Apologies I was being perhaps a little lazy with my pasting. I have my yaml configured in the second version below.
When I input the suggested format above:
switch:
- platform: xiaomiplug
host: 10.39.167.132
name: Bedroom Heater
token: 611b12ecbf1cbfdf3270b6a3ec689cb6
- platform: xiaomiplug
host: 10.39.167.147
name: Spare Plug
token: 4c7f07159d7f566def6e57be95a00c4a
- platform: xiaomiplug
host: 10.39.167.102
name: Lounge Lamp
token: 7020d183d02942cc939b7bbab0047902
The error it returns is:
2017-07-13 22:02:47 ERROR (Thread-1) [homeassistant.util.yaml] mapping values are not allowed here
in "/home/homeassistant/.homeassistant/configuration.yaml", line 100, column 11

in "/home/homeassistant/.homeassistant/configuration.yaml", line 100, column 11
Then when I use the following (which is how it works with one single socket):
switch:
- platform: xiaomiplug
host: {IP Here}
name: Bedroom Heater
token: {Token Here}
- platform: xiaomiplug
host: {IP Here}
name: Spare Plug
token: {Token Here}
- platform: xiaomiplug
host: {IP Here}
name: Lounge Lamp
token: {Token Here}
Returns:
2017-07-13 22:04:42 ERROR (Thread-1) [homeassistant.util.yaml] while scanning for the next token

in "/home/homeassistant/.homeassistant/configuration.yaml", line 110, column 44

in "/home/homeassistant/.homeassistant/configuration.yaml", line 110, column 44
Oh, I have misinterpreted the error message. It’s complaining about a tab (“\t”) which isn’t allowed. Please check your yaml file for tabs and replace it with spaces? And you are right. The correct format is:
switch:
- platform: xiaomiplug
host:
name: Bedroom Heater
token:
- platform: xiaomiplug
host:
name: Spare Plug
token:
- platform: xiaomiplug
host:

A pity. My guess was wrong. I cannot help from here, sorry.
Good news: I found a proper piece of code here: https://github.com/rytilahti/python-mirobo/blob/master/mirobo/protocol.py
I think the context[‘_’][‘token’] parts will do the magic and fix the checksum error. The best approach would be to extend the mirobo component by an additional device (xiaomi wifi plug). The quick and dirty solution is a merge of the protocol.py into @xavV component.
I have done some work: https://github.com/syssi/xiaomiplug
Can you test the component? It’s untested. You have to remove the old implementation (xiaomi folder & custom_component/switch/xiaomiplug.py) and use the new one. The new component is now called “xiaomiplug”.
Working fine for me.
I have two WIFI devices: a smart socket and a smart strip.
I tested both of them and switch with correct states from Xiaomi Mi Home and Home Assistant.
THANKS a lot
Please update the component. The current state of the plug is polled again now.
Updated and keeps working. Although it takes almost 20 seconds to update state in Home Assistant when my “smart strip” is switched from “Mi Home” app. I don’t know if it took less before or it’s the same.
By the way: I’ve been experimenting a little with the miio command line and it seems to me that both smart socket and smart strip have temperature sensors in addition to switch status.
When I try:
miio --control MY_STRIP_IP --method get_prop --params ‘[“power”,“temperature”]’
it answers:
INFO Attempting to control 192.168.1.218
INFO Got result:
[
“on”,
46.22
]
So it seems that it measures internal temperature.
¿Any way that this sensor could be incorporated?
The below are my sensors for a air purifire
You may refer to it.
platform: command_line
name: Air Purifier Humidity
command: miio --control 192.168.0.15 --method get_prop --params ‘[“humidity”]’

scan_interval: 120
platform: command_line
name: Air Purifier Mode
command: miio --control 192.168.0.15 --method get_prop --params ‘[“mode”]’

scan_interval: 120
I will provide the temperature as attribute. Do you know more interesting attributes? The plug does not provide a power consumption, right? The zigbee version does report the power consumption f.e.
The interval is unchanged. Good to know the state is populated properly again.
Thanks, that was my “Plan B” if it couldn’t be done elseway. But it seems to me that this way we are throwing too many “requests” to the same device: one via the python component to retrieve the power state another one for each property… An optimal way could be to retrieve all of them in a single call providing the array of params in the same request…
Thanks any way.
