Some people have a hard time choosing between Home Assistant and SmartThings as their main Smart Home hub. But I will say why don’t you have them both working at the same time. I will show you how to do that in this video.

Home Assistant and SmartThings Integration

What will you see in this article

I will integrate the Samsung SmartThings hub and Home Assistant, so every device connected to the SmartThings will be also visible and controllable by Home Assistant.

Check the current Amazon price of the Samsung SmartThings Hub v3 here – link

You may wonder why I’m doing this? Why I don’t just use Home Assistant or SmartThings only? And the simple reason is that I want to easily add Zigbee and Z-wave devices to my Home Assistant and SmartThings will greatly help me with that.

I know that there are some Zigbee and Z-wave dongles out there that I could use and they are working locally, but as far as I know their support is not as good as with the SmartThings and they are almost the same price as the v3 hub. So I decided to give the Home Assistant and Samsung SmartThing v3 a try.

Let’s see what will happen.

Token for the Home Assistant and SmartThings Integration

You will need a Personal Access Token with enough permissions to be able to integrate Home Assistant and SmartThings. To get it just follow these steps:

Generating PAT for the Home Assistant and SmartThings Integration

  • Click ‘Generate token’. Copy this token and save it somewhere safe you will not be able to see it again after you close this window.

You’ll need a SSL Remote Connection

You will need a SSL enabled remote access to your Home Assistant to proceed further.

You have two options for that:

  1. To use the Home Assistant paid cloud service called Nabu Casa
  2. To read and implement the instructions in my article absolutely for free.

I recommend the second option, so go read my article and come back right here after you are ready.

Adding SmartThings integration in Home Assistant

The Home Assistant and SmartThings integration is very clean as there are no additional dependencies or bridges.

That means this should work without issues for a long time and you don’t have to worry so much that it will break with the next Home Assistant release.

So let’s just integrate the Home Assistant and SmartThings.

Open Home Assistant and go to:

Configuration > Integrations > Big Plus Orange Button (lower right corner)

Search for “SmartThings” and click on it

Click “SUBMIT” on the Confirm Callback URL dialog. Again double check that you are using the SSL enabled Home Assistant Remote Access.

Next, just paste the token (PAT) from the Samsung SmartThings in the next dialog and click “SUBMIT” again.

Then you can choose a location, click on OPEN WEBSITE button, after that click on DONE and finally Allow.

When you return back to your Home Assistant you should see a similar Success window.

When you click FINISH you will see the SmartThings in the Home Assistant integrations list with all devices and entities that you have added in SmartThings available and ready to use.

Have in mind that you have to restart your Home Assistant if you add new devices in SmartThings and they will be automatically synchronised.

Question for You!

I cannot see my Amazon Echo (Alexa) device in Samsung SmartThings v3 for some reason.

Maybe i’m missing something.

They are in the same WIFI and I even added SmartThings skill in my Echo which is working fine, but under voice assistant category I see only Google Assistant.

Only Google Assistant is available in SmartThings app under Voice assistant category

Can you give me a hint in the comments below? I will be very thankful.

Home Assistant and SmartThings demo

I will quickly demonstrate you how I can control in Home Assistant the devices added in Samsung SmartThings v3 hub.

The easiest way to manually test if everything is working is to create an Entities card in Home Assistant with all the Entities from the Samsung SmartThings integration.

Just click on the three dots in the upper right corner of the Home Assistant web interface, choose “Configure UI”, and the big plus orange button after that. Select Entities card

From the dropdown menus of the card just select your SmartThings entities and click SAVE button.

Now you can open the SmartThings App and enable and disable your devices from Home Assistant and from the SmartThings App to check if they are in sync.

When enable the Device in Home Assistant it gets enabled in the SmartThings app and Tuya Smart life as in the example above

A single device added in SmartThings may be represented by one or more of the available Home Assistant Platforms. If you need more info just read the Home Assistant documentation about SmartThings – it is very good.

Enabling Debug log level

When creating an automation or script in Home Assistant with a device added from SmartThings you may need some additional information to catch fired events or pressed buttons. In that case it is a good idea to set the log level to debug.

Here is how:

Just copy and paste the lines below in your configuration.yaml file

logger:
  default: info
  logs:
    homeassistant.components.smartthings: debug

Then you have to restart your Home Assistant and you can see the detailed log of your devices under the Configuration > Logs menu.

You can catch the events that you want to integrate Home Assistant and SmartThings better.
