njsTuya

Openhab interface for Tuya home automation devices sold under various names.

This is a wrapper script for codetheweb/tuyapi. https://github.com/codetheweb/tuyapi and unparagoned/cloudtuya https://github.com/unparagoned/cloudtuya

There is support for local control after identifying the localKey for each device. And basic support for devices setup using the tuya or smartlife app. Using the tuya app login email and pass.

Install Instructions:

If nodejs and npm are installed, install the package from npm (otherwise obtain nodejs and npm first):

openhab=/etc/openhab2
cd $openhab/scripts
sudo npm install unparagoned/njsTuya

Test Install

Run the following which should find all devices on your netork and return their state.

node node_modules/njstuya

Configuration

To use create a rule which sends a command to the script

var resp = executeCommandLine("node /etc/openhab2/scripts/node_modules/njstuya" + command, 50000)
logInfo("Tuya", "Run Command: [{}] Result {}", command, resp)

To use the following items and rule as an example copy the files to Openhab configuration directories:

cp node_modules/njstuya/items/* $openhab/items/
cp node_modules/njstuya/rules/* $openhab/rules/

Once you have your id, ip, key for a device uncomment the first rule un temperature.rules and enter in your device details.

If you know the device id or ip try running, to get the state and dps options for a specific device

node njstuya.js -id 213klj349sdfjl324po32 -get '{ "schema": true}'
node njstuya.js -ip 123.0.0.2 -get '{ "schema": true}'

Cloud setup

You can pass the cloud email and arguments through the cli, or complete the key.json.rename and rename it to key.json

It is reccomended to put the details into key.json in the folder ./scripts/node_modules/njstuya/

 {
   "userName" : "d@yahoo.com",
  "password": "yourpassword",
  "countryCode": "44",
  "bizType": "smart_life",
  "region": "EU"
 }

bizType can be 'tuya', 'smart_life'

Then you just need to run

node njstuya.js -mode cloud -id DEVICEID COMMAND

Otherwise to pass all arugments without config enter the email/pass/international phone code/region

node njstuya.js -mode cloud -user email -pass password -biz smart_life -code 44 -region eu -id DEVICEID COMMAND

code = internatinal dialing code region = 'eu' | europe 'ay' | Asia 'az' | Americas biz = 'tuya' 'smart_life'

Node installation

using package manager

curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash -
sudo apt-get install -y nodejs

The following shouldn't be necessary but might be if you have old version of node and don't have timeout.

#update node if you have an old version and have problems
sudo npm cache clean -f
sudo npm install npm@latest -g

sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/nodejs
#install timout if you get errors about timeout
pip install timeout

Configuration to obtain private key

You have to create an item with with your devices ip, id and key.(Or if you just have one device you can hardcode the parameters into the exec command as below) This involves MIM of the connection.

Android

  1. Install "Package Capture" from play store.
  2. When you first open it it will ask you to install a certificate, this is needed for it to work.
  3. In the top bar there are two "Play" symbols. The one with a 1 allows you to capture packets from certain apps.
  4. Click on that and select "Smart Life" from the list of apps.
  5. It will popup about setting up a vpn and will then start capturing packets.
  6. Open Smart Life and on the screen showing "All Devices" pull down the screen to cause a refresh.
  7. Go back to Packet Capture and hit the Stop button at the top.
  8. You should now have an entry below showing x number of captures.Tap that to open it. In mine I had to open the last packet in the list that was marked as SSL.
  9. Scroll down through the first few blocks and you should see a large JSON block This contains a lot of code but if you scroll through it you should see line like the ones below

"devAttribute": 0 "name": Smart Socket 4" "timezoneId": "Europe/London" "localKey": "XXXXXXXXXXXXXXX"

All Other methods

There are alternative methods which can be found here: https://github.com/codetheweb/tuyapi/blob/master/docs/SETUP.md

Useage Instructions

Commands are:

  1. General command:
node njstuya.js -mode MODE -ip DEVICEIP -id DEVICEID -key DEVICEKEY COMMAND

MODE is:

where COMMAND is:

Example:

node njstuya.js -ip 10.0.0.2 -id 213klj349sdfjl324po32 -key 342kljerw98 ON

If no the ip and id are missing then the script will scan the network and return the state schema(state) of all devices.

node node_modules/njstuya

All commands return the state of the switch.

  1. GET/SET commands for dps:

dps is for local mode only, see below (2.b) for cloud option

node njstuya.js -ip DEVICEIP -id DEVICEID -key DEVICEKEY -set GETCOMMAND

Where the GETCOMMAND should be of the following format, including quote marks '{ "dps": 1 }'

WINDOWS COMMAND FORMAT

If you are on windows or just using the command line on linux you can use the old syntax "{ \"dps\": 1 }". But you may have issues using this format through the set command in openhab.

To get all the dps options for your device use the get command to get the schema Example:

node njstuya.js -ip 10.0.0.2 -id 213klj349sdfjl324po32 -key 342kljerw98 -get '{ "schema": true}'

Set commands are similar but also have a state

node njstuya.js -ip DEVICEIP -id DEVICEID -key DEVICEKEY -set SETCOMMAND

Where SETCOMMAND should be of the following format, including quote marks '{ "dps": 1, "set": true }' or '{"multiple":true,"data":{"1":false,"7":false}}' Note for windows you have to use the following format for the command line "{ "dps": 1, "set": true }". But you may have other issues if you have openhab running on windows.

Example:

node njstuya.js -ip 10.0.0.2 -id 213klj349sdfjl324po32 -key 342kljerw98 -set '{ "dps": 1, "set": true }'
node njstuya.js -ip 10.0.0.2 -id 213klj349sdfjl324po32 -key 342kljerw98 -set '{"multiple":true,"data":{"1":false,"7":false}}'

Get

You may need to play about with the dps if you have multiple function for your device.

2.b SET commands for cloud mode:

node njstuya.js -mode cloud -id DEVICEID -set "{\"command\": \"temperatureSet\", \"payload\" : { \"value\": 30 }}"
node njstuya.js -mode cloud -id DEVICEID -set  '{"command": "turnOnOff", "payload" : {"value": 1 }}'
node njstuya.js -mode cloud -id DEVICEID -set  '{"command": "colorSet", "payload" :{"color": "{ \"hue\": 50, \"saturation\": 50, \"brightness\": 50}" }}'

Habpanel

Here is how you would use a slider in habpanel to change the set temp.

<div class="name">Set Target Temp: {{itemValue('KitchenThermostatTargetTemp')}}</div>
<div ng-init="slider = { value: itemValue('KitchenThermostatTargetTemp'), options: { floor: 0, ceil: 40, step: 1, showSelectionBar: true } };"></div>
<rzslider rz-slider-model="slider.value" rz-slider-options="slider.options" ng-click="sendCmd('KitchenThermostatTargetTemp', slider.value)"></rzslider>

Usage

The following is an extract from Habpanel which shows how to send commands to the item. Send ON,OFF,TOGGLE to LivingRoomCommand.
