I think you’d better delete a ‘#’ in line 163 
I would love to use it. But when I am trying to test it, I am getting CheckSum error:
File “/usr/lib/python3.6/site-packages/construct/core.py”, line 2272, in _parse
raise ChecksumError(“wrong checksum, read %r, computed %r” % (hexlify(hash1), hexlify(hash2)))
construct.core.ChecksumError: wrong checksum, read b’ffffffffffffffffffffffffffffffff’, computed b’86f9dfc783dd2b635f17750e28fc898c’
Am I doing something wrong?
And maybe I should note that I am also using Xiaomi Air Purifier 2 bulitin integration.
Thanks, fixed now.
Sorry, no idea… Looks to me like this error is unrelated to the custom platform code.
I recommend you use python3.5.
If you use HASSBIAN, it works well.
Thanks @bezkod for the initial work. I didn’t know your custom_component and did the same like you as proof of concept:
If the component works fine I will merge the code into fan/xiaomi_miio soon in order to support the Xiaomi Air Humidifier officially in future.

@bezkod Our code differs in one feature: Is the LED of the Air Humidifier controllable? Did you remove set_led_on and set_led_off on purpose? Could someone (@af950833, @itchaboy) test all exposed services of the component? Thanks in advance!
Another request: Could someone provide the output of following mirobo (cli, part of python-miio) calls for the air humidifier:
# ip and token needs to be adapted
bin/mirobo --ip 192.168.1.71 --token 3d5f7ae53b51aa312e464b150b37453b -d info
bin/mirobo --ip 192.168.1.71 --token 3d5f7ae53b51aa312e464b150b37453b get_prop '["power", "mode", "temp_dec", "humidity", "buzzer","led_b", "led"]'
how do I go about adding a custom component? Would I add the following folder to my config folder? custom_components/fan/custom_component.py

from HA 0.61.0 the servicess are not working, so I removed all service in the code and using upper code as custom_components.
Also I wanna let you know that there is no LED Brigtness in Air Purifier Pro. I am also using it after removing the service"LED Brightness" in HA 0.61.1
It looks like there is not attribute “led_b” or “led” for the Air Humidifier. Could you execute this two commands for testing:
mirobo --ip 192.168.0.25 --token 689c4056fe28ebb3a2e8c2fe350e51ba raw_command get_prop '["power", "mode", "temp_dec", "humidity", "buzzer","led"]'
mirobo --ip 192.168.0.25 --token 689c4056fe28ebb3a2e8c2fe350e51ba raw_command get_prop '["power", "mode", "temp_dec", "humidity", "buzzer","led_b"]'
One of the outputs will contain a “null” value.
Just copy the file
to custom_components/fan/xiaomi_airhumidifier.py and add the configuration to your
# configurations.yaml

In the Xiaomi App’s Air Humidifier, there is no LED on/off but there is the LED brightness.
In the LED brightness, 2 is off, 1 is Dim light and 0 is Bright light.
I used it as a sevice in HA 0.60.1 and it worked well.
Perfect! I updated the component.
I always thank you
Your screenshots are showing some missing features:
- Target humidity
- Sounds (Volume?)
- Parental controls
We can extend the component if you provide some further testing.
I miscommented for LED level.
2 is off, 1 is Dim light and 0 is Bright light.(These are corrent)
What test do I have to do for extend component?
Please let me know it and I will follow it up~
Please provide the feedback of:
