This programm allows to controll and monitor Luminea smart plugs via mqtt. This should also work with almost all other tuya devices, provided therre is a fitting device class. At the moment, only the nx-4458 is supported. More will follow.

This bridge is mostly based on the work of: https://github.com/codetheweb/tuyapi

• Easy intigration of luminea (tuya) device into HomeAssistant
• Auto reconnect to tuya device
• Supports Homeassistant Auto-Discovery
• Easily extendable

At the moment:

• luminea nx-4458

More devices may follow when I can test them.

• nodejs (https://nodejs.org/en)
• nvm (https://github.com/nvm-sh/nvm)

The bridge requires node.js version 18 and is based on the following libs:

• https://github.com/codetheweb/tuyapi
• https://github.com/mqttjs
• https://github.com/log4js-node/log4js-node
• https://github.com/tj/commander.js

nvm install 18
nvm use 18
sudo ln -s $(realpath `which npm`) /usr/local/bin/npm
sudo ln -s `which node` /usr/local/bin/node
sudo useradd luminea2mqtt -s /bin/bash -d /opt/luminea2mqtt
sudo mkdir /opt/luminea2mqtt
sudo chown luminea2mqtt /opt/luminea2mqtt -R
sudo su - luminea2mqtt
git clone https://github.com/dennis9819/luminea2mqtt.git /opt/luminea2mqtt/bridge
cd bridge
npm install
cp config-example.yaml config.yaml

Configure your devices and mqtt settings (still as user luminea2mqtt):

vim config.yaml

sudo -u luminea2mqtt node /opt/luminea2mqtt/bridge/src/index.js -c /opt/luminea2mqtt/bridge/config.yaml

sudo cp -p /opt/luminea2mqtt/bridge/luminea2mqtt.service /etc/systemd/system/luminea2mqtt.service
sudo systemctl daemon-reload
sudo systemctl start luminea2mqtt

The bridge requires a config file to specify mqtt connection information and the device configuration.

An example is given in config-example.yaml

mqtt:
  host: "127.0.0.1"
  port: 1883
  username: "username"
  password: "password"
  clientid: "test"
  prefix: "luminea2mqtt"

These values define the port and ip of the server, as well as the credentials for this client. All values must be specified. Make sure that the clientid is unique. The prefix is the prefix of all mqtt topics.

autodiscover:
  enabled: true
  topic: homeassistant

This enables auto discovery for home assistant. (See https://www.home-assistant.io/integrations/mqtt/#mqtt-discovery)

• enabled: enables autodiscovery.
• topic: topic prefix for discovery messages

devices:
  - id: "sqy709956ply4inkx6ac87"
    key: "xxxxxxxxxxxxxxxx"
    friendlyname: "device1"
    refresh: 30 #refresh intervall in s
    type: luminea_nx_4458

• id and key: Specify id an local key of tuya device. There are severeal tutorials avaliable online on how to get these keys. This depends on the app you have used to register your devices if you don't want to reset them. If you use iO.e, see extractkeys.md on how to get extract these values.
• friendlyname: The displayname of the device. Also sets the base topic for this device as following: /{mqtt.prefix}/{friendlyname} If this property is not set, friendlyname defaults to the id. /get and /set topics are also used for turning the switch on or off.
• refresh: refresh intervall in s
• type: name of device class. Class files are located in ./src/modules

Device classes are located in ./src/modules. On intialization, each device in the config is initialized one by one. The js file, specified by type is loaded and a new instance of the exported class is created.

You can create your own devices in ./src/modules. You can use luminea_nx_4458.jsas an example. Your class should extend DeviceBase:

class Lineplug extends DeviceBase {
    init() {
        
    }
    startWatcher() {
        
    }
    stopWatcher() {
        
    }
}

These functions must be implementd:

• init is called on creation. You can setup variables here
• startWatcher is called after the connection is established
• stopWatcher is called after disconnect (stop timers, unsubscribe mqtt,...)

These functions can be implemented:

• pushAutodiscover(deviceConfig) is called to publish the device config

These variables are available:

• this.mqtt reference to the mqtt client
• this.topicname String: topic prefix
• this.topic_get String: topic get
• this.topic_set String: topic set
• this.topic_state String: topic state
• this.deviceid String: device id
• this.intervall_refresh Number: refresh intervall (ms)
• this.reconnect_timout Number: reconnect intervall (ms)
• this.lastdata Object: buffer for last state
• this.logger reference to log4js logger
