or add to your package.json

"node-red-contrib-smartthings": "*"

this is how it will looks like:

Every device node will have an Account property which must be configured.

You only have to create this configuration once and use it in all device nodes.

Configuration Node Edit Window:

Configuration Node Configuration Node

As you can see, the only relevant information here is a token


In order to allow the plugin to have access to your devices using Smartthings API you must provide a token

You can get a Smartthings Token here:


In order to receive events from SmartThings we need to Install a custom SmartApp.

You can find the SmartApp code here: SmartApp

To install the SmartApp you can follow these steps:

NOTE: You need to use the SmartThings Classic mobile app for installation AFTER which you can access the installed SmartApps using the new SmartThings mobile app

  1. Copy the SmartApp code to clipboard ( Ctrl + C )
  2. Login to the IDE at (create a Samsung Account one if you don't have one)
  3. Click on "My Locations" and then click on the name of the location where you want to install the SmartApp
  4. Click on "My SmartApps"
  5. Click on "+New SmartApp" on the top right
  6. Click "From Code"
  7. Paste the code (Ctrl+V) copied from Step 1 into the editor and click "Create"
  8. Click "Publish" and then "For me" on the top right
  9. To install the SmartApp, open your SmartThings Classic App on your phone, click on the Automation icon at the bottom bar right corner of the main screen. Now click on the "SmartApps" tab on the top right of the screen. Scroll down to the bottom and click on "+Add a SmartApp". Then scroll down to the bottom and click on "My Apps". (NOTE: if you don't see "My Apps" you need to use the SmartThings Classic app, if you don't see the SmartApp in "My Apps", then you may have installed the code in the wrong location, check step 3 again)
  10. Scroll down the "My Apps" section until you see the new SmartApp you just created and click on it on install it. You're done! To open/configure the app in future follow step 11.
  11. After installing the SmartApp, configure/open it by clicking on the "Automations" icon and then click on "SmartApps" on your phone. NOTE: Clicking on the SmartApp in the "My Apps" section will install a NEW instance of the SmartApp instead of opening the existing installation.

Configuring the SmartApp

  1. The first field is the webhook address. This must be your NodeRed public address followed by /smartthings/webhook. So, if your NodeRed public address is it will be something like this You must use HTTPS. Otherwise Smartthings hub will not call your webhook

  1. Has been added an option Local Network. You can turn this on if NodeRed is running inside your local network. Like: http://192.168.0.xx/smartthings/webhook. This option will only work with a local ip address.

  2. Select all your devices. Only the selected devices will send events back to NodeRed. Those not selected will not have theirs status updated.

Debugging the SmartApp

If you are having any issue with the nodes not updating after the deploy, usually, it is a misconfiguration of the SmartApp.

To debug the communication between the SmartApp and the NodeRed WebHook you can follow these steps:

Device Nodes

Once in NodeRed at SmartThings group you will see many devices nodes. Switch, Level, Color, Humidity, Motion, Contact, etc..

Every node will keep its state. Every time a device state changes a message will be send to the output node with the msg.topic of device with all relevant informations at the msg.payload property.

Device changes are received through the webhook you set up at SmartThings Developers Portal.

All device nodes can receive at its input a message with the msg.topic of update to force the output of the current device state. This is useful when handling a request, for example.

Some devices can have their state changed. You can turn on a light, change level and color, or, open your door.

For example, to turn on a switch you can send a message to its device node:

    topic: "switch",
    payload: {
        value: 1

This will turn on the device using Smartthings API and send the current status to the output.

This will be documented inside the NodeRed help window for each node.


And... if this helps you to save time and money. Pay me a coffee. :-)
