xiaomi-mqtt

A Bridge between the Xiaomi Mi Smart Home Gateway and the Mqtt broker.

Xiaomi-mqtt exchanges data between the xiaomi gateway and the mqtt-broker at a low-level, principally based on the device sid (Security Identifier?). The automation and dashboard tasks are implemented at a higher level. Node-RED is the perfect tool to use for this purpose.

Installation

sudo npm install -g xiaomi-mqtt

Installation from GitHub

Clone the source repository directly from GitHub to a local folder:

git clone https://github.com/cflurin/xiaomi-mqtt.git

Local Installation:

cd xiaomi-mqtt
npm install

Configuration

Copy the config.json file to the .xiaomi-mqtt folder inside of your home folder.

mkdir ~/.xiaomi-mqtt
cp config.json ~/.xiaomi-mqtt/

On Linux the full path for your config.json would be ~/.xiaomi-mqtt/config.json.

Edit ~/xiaomi-mqtt/config.json to fit your requirements:

{
  "xiaomi": {
    "serverPort": 9898,
    "multicastAddress": "224.0.0.50",
    "multicastPort": 4321,
    "password": "FFF..."
  },
  "mqtt": {
    "url": "mqtt://127.0.0.1",
    "port": 1883,
    "username": "foo",
    "password": "bar",
    "topic_mode": "short",
    "topic_prefix": "xiaomi"
  },
  "loglevel": "info",
  "heartbeatfreq": 6,
  "dataFormat": "parsed"
}

"topic_mode": <"short"> | <"full"> | <"both">

• short default
• full allow you to do some topic filtering directly on client side.
• both 2 topics are sent, short and full.

"loglevel": <"debug"> | <"info"> | <"warn"> | <"error">

Replace 127.0.0.1 with the address of your mqtt broker.

Set dataFormat to raw to get data without parsing.

By default the gateway send heartbeat every 10s which can do some pollution when testing/debug, the counter parameter in config named heartbeatfreq avoid this, in the example above set to 6 means only send a MQTT message each 6 heartbeat, so each 60s. Note this apply only to gateway heartbeat not the device's one.

Usage (global installation)

Use xiaomi-mqtt or xm to run xiaomi-mqtt. Use ctrl c to stop xiaomi-mqtt.

Usage (local installation)

In the xiaomi-mqtt folder.

Use npm start to run xiaomi-mqtt. Use ctrl c to stop xiaomi-mqtt.

mqtt API

If the configuration option topic_mode is set to short or both, the data (payload) is sent/received in a JSON format using following topics:

• xiaomi/from
• xiaomi/to/read
• xiaomi/to/write
• xiaomi/to/get_id_list

Note: Have look at: How to benefit of the full topic option

Howto examples

At start and stop xiaomi-mqtt sends following messages.

start
