I built a free installer that automatically turns off the display on compatible Samsung air conditioners
Hi everyone!
I created an open-source tool for Samsung air conditioner owners who want the unit’s display to turn off automatically whenever the AC is turned on.
The installer creates a Rule directly in your own SmartThings account. When the air conditioner changes to on, the Rule waits five seconds—or another delay you choose—and sends only the command that turns off the display.
Once configured, everything runs in the SmartThings cloud. You do not need to keep your computer running, maintain a server, use Home Assistant, create an Alexa Skill, or pay a subscription.
The guided setup:
- Finds your SmartThings locations and compatible air conditioners automatically
- Lets you choose the device and delay
- Shows the exact action before making any changes
- Requires confirmation before creating, updating, or deleting a Rule
- Can run an optional guided test
- Provides commands to check, update, or remove the configuration
You do not need to create a Personal Access Token, find a deviceId, configure OAuth, or edit an .env file. Authentication is handled in the browser by the official SmartThings CLI, and the project does not receive or store your credentials.
Basic installation:
- git clone https://github.com/m3ryck/samsung-ac-display-automation
- cd
- npm install
- npm run setup
Requirements:
- A compatible Samsung air conditioner already connected to SmartThings
- Display/lighting control available for the device in the SmartThings app
- Node.js 24.8.0 or newer
- Windows, macOS, or Linux
After setup, you can close the terminal and even delete the downloaded project folder. The automation remains active in SmartThings.

Feedback, compatibility reports, and contributions are welcome — especially if you can share which Samsung AC model you tested it with.
