Xiaomi Humidifier support

Currently only Xiaomi AirPurifier is supported, but Xiaomi Humidifier is also supported by miio. Looks like adding support for Humidifier is not something needed to be done from scratch.
I tried to customise xiaomi_miio platform, but not much luck for now :slight_smile: Would be great to have it supported.

miio docs: https://github.com/aholstenson/miio/blob/master/docs/devices/humidifier.md

The linked miio is different one from one that is used in homeassistant, however, the support for those is also available (https://github.com/rytilahti/python-miio/blob/master/miio/airhumidifier.py), so it would “just” require someone to write a platform to support this.

Ok, got it working with slight modification of AirPurifier platform.
Here is the link to two source files:

I think you’d better delete a ‘#’ in line 163 :slight_smile:

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 --token 3d5f7ae53b51aa312e464b150b37453b -d info

bin/mirobo --ip --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 --token 689c4056fe28ebb3a2e8c2fe350e51ba raw_command get_prop '["power", "mode", "temp_dec", "humidity", "buzzer","led"]'
mirobo --ip --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 :slight_smile:

Your screenshots are showing some missing features:

  1. Target humidity
  2. Sounds (Volume?)
  3. Parental controls

We can extend the component if you provide some further testing. :slight_smile:
