Xiaomi Mi Robot Vacuum - Domoticz Python plugin

This plugin uses the Python-miio library.

See this link for more information on the Domoticz plugins.

How it works

Plugin provides: Status, Control, Fan Level, Battery, Care status devices

Status: show current status in readable layout of switch. Status updates by polls (interval) and when you click Control device (for instant status change).

Control: for sending commands.

Fan Level: for adjusting suction power. (MiHome app related: Quiet=38, Balanced=60, Turbo=77, Max=90)

Battery: since 0.0.4 as new device

Care: since 0.1.0 new 5 devices (care status + reset tool)

Since 0.1.0 plugin uses wrapper-server for python-miio lib. It helps to use this plugin in Domoticz without blocking mode.

Since 0.1.2 wrapper-server (MIIO Server) runs outside plugin due limits of domoticz python plugin system.

Installation

Before installation plugin check the python3, python3-dev, pip3 is installed for Domoticz plugin system:

sudo apt-get install python3 python3-dev python3-pip

Make sure you have libffi and openssl headers installed, you can do this on Debian-based systems (like Rasperry Pi) with:

sudo apt-get install libffi-dev libssl-dev.

Also do note that the setuptools version is too old for installing some requirements, so before trying to install this package you should update the setuptools with:

sudo pip3 install -U setuptools.

Also need to install virtualenv:

sudo pip3 install -U virtualenv.

Then go to plugins folder and clone repository:

cd domoticz/plugins
git clone https://github.com/mrin/domoticz-mirobot-plugin.git xiaomi-mirobot
cd xiaomi-mirobot
virtualenv -p python3 .env
source .env/bin/activate

# and then:
pip3 install -r pip_req.txt 
# or pip3 install gevent msgpack-python python-miio==0.3.1

Since 0.1.2 need some prepare of MIIO Server to run as service:

Open and edit miio_server.sh by vi/nano:

nano miio_server.sh

# 1. Check and update absolute path to miio_server.py
# 2. Update IP and TOKEN for robot
# 3. Optional. Change MIIO server host-port bindings if need it

# file miio_server.sh
DAEMON_USER=root
DAEMON=/home/pi/domoticz/plugins/xiaomi-mirobot/miio_server.py
DAEMON_ARGS="192.168.1.12 476e6b70343055483230644c53707a12"
DAEMON_ARGS="$DAEMON_ARGS --host 127.0.0.1 --port 22222"
#

Check path to python3 which python3. By default is /usr/bin/python3. If your path different than default, update miio_server.py first line with your path.

#!/usr/bin/python3

For run as system service:

sudo chmod +x miio_server.py
sudo chmod +x miio_server.sh

# check your path here:
sudo ln -s /home/pi/domoticz/plugins/xiaomi-mirobot/miio_server.sh /etc/init.d/miio_server

# add to startup
sudo update-rc.d miio_server defaults
sudo systemctl daemon-reload

# if you want to remove from startup
sudo update-rc.d -f miio_server remove

Run server and test script:

sudo service miio_server start
sudo chmod +x test.py
sudo ./test.py

# to stop miio server service
sudo service miio_server stop

Also you can run MIIO Server manually and look log output:

sudo ./miio_server.py 192.168.1.12 476e6b70343055483230644c53707a12 --host 127.0.0.1 --port 22222

# then you can run test
sudo ./test.py

If server and test is ok, time to restart the Domoticz:

sudo service domoticz.sh restart

Now go to Setup -> Hardware in your Domoticz interface and add type with name Xiaomi Mi Robot Vacuum.

Field	Information
Data Timeout	Keep Disabled
MIIOServer host:port	by default 127.0.0.1:22222
