Hi all,
I built a SmartThings Schema Connector for LG refrigerators using LG’s official ThinQ Connect API (Personal Access Token based - no cloud scraping or unofficial APIs).
What it does:
- Fridge and Freezer temperature - view and adjust, with decimal precision (0.1°)
- Express Mode (ice boost) - toggle on/off, pressable from the app
- Power Save status - view
- Door status - open/closed, via standard Contact Sensor (so it works in Routines automatically)
- Water Filter - months used
Automatically shows temperatures in Fahrenheit for US accounts and Celsius everywhere else, based on your SmartThings account’s country.
How to install:
- Get a Personal Access Token from connect-pat.lgthinq.com (must be logged in with a native LG account - Google/Facebook/Amazon social logins won’t work with the API)
- Open this invitation link on your phone with the SmartThings app installed: SmartThings Channel and Drivers
- Log in with your PAT and country code
Known limitations:
- LG’s hardware only stores whole-degree Celsius setpoints internally, so there’s a small unavoidable rounding when displaying in Fahrenheit
- Tested primarily on a 2-door model (2RES1VE62PFWA) - other models may report slightly different data, let me know if you hit issues
Big thanks to @homeagain, who tested this extensively on his real fridge and helped me track down and fix several bugs before this was ready to share.
Free to use, same as my other LG integration (washer/dryer). Let me know if you run into any problems!
