Home Assistant Custom Integration for Midea dehumidifiers (Inventor EVA II PRO WiFi / Comfee MDDP-50DEN7 appliances).

Author: Andrea Barbaresi =2020-2024=

This repo contains a Home Assistant custom integration for EVA II PRO WiFi Smart Dehumidifier appliance by Midea/Inventor. It has been reported that the custom integration can work also with Comfee MDDP-50DEN7 appliance.

This custom component is based on python library midea_inventor_lib.: see library's readme and prerequisites to be able to control your device on Home Assistant.

You can buy Midea/Inventor/Comfee smart dehumidifier appliances (WiFi version) on Amazon sites (the links below contain my referral code):

Installation instruction

HACS

Update HomeAssistant to version 0.96.0 or newer
In HACS Store, search for [barban-dev/midea_dehumidifier]
Install the custom integration
Activate midea_dehumidifier custom integration on your HA's configuration yaml file (see instructions below)

Manual

Update HomeAssistant to version 0.96.0 or newer
Clone this repo
Copy the custom_components/midea_dehumidifier folder into your HA's custom_components folder
Activate midea_dehumidifier custom integration on your HA's configuration yaml file (see instructions below)

Activate midea_dehumidifier custom integrations

Add the following section in your configuration.yaml & restart HA (use the same username and password of your INVmate II App):

midea_dehumidifier:
  username: user@example.com
  password: passwordExample

As usual, you can hide your secret password by means of !secret notation by specifing it in secrets.yaml

Alternatively, if you prefer, sha256password parameter can be used instead of the password one to specify password's sha-256 hash

midea_dehumi:
  username: user@example.com
  sha256password: cf76d55503cdee3....

If everything is ok, you will find the following two new entities in your HA dashboard:

humidifier.mideadehumidifier[Device_ID]
sensor.mideadehumidifier[Device_ID]_humidity

By means of the humidifier entity, you can control your appliance whereas the sensor reports the detected current humidity on your environment.

Lovelace card for midea_dehumidifier entity

Add the following part of code to have a lovelace card representing your device and able to control all its features (change "12345678901234" with your device's ID):

configuration.yaml

  dehumidifier_fan_mode:

Installation Troubleshooting

After installation, final result should look similar to this:

\\<ha_ip_address>
    └── config

        │   └── midea_dehumidifier
        │       ├── __init__.py
        │       ├── humidifier.py
        │       ├── manifest.json

                            └── libfiles...

If you cannot find the midea_dehumidifier entity on HA, check the logs generated by HA to track the issue. In order to set DEBUG level for midea_dehumidifier, add the following in your HA's configuration yaml:

logger:
  default: info
  logs:
    custom_components.midea_dehumidifier: debug
    custom_components.humidifier.midea_dehumidifier: debug
    custom_components.sensor.midea_dehumidifier: debug

Copy /midea_inventor_lib folder on \deps\lib\python3.6\site-packages\ of your HA's configuration shared folder.
