Hey everyone, I wanted to share my recent experience connecting an older Samsung refrigerator (RS22HDHPNSR, 2014 model) to the SmartThings app on my iPhone 12. I thought it might be a breeze, but it turned out to be a bit of a puzzle! 
The Challenge:
I moved into a place that already had this fridge, and I was excited to integrate it into my smart home setup. The original manual mentioned a different app, which wasnât available on my iPhone. I followed the instructions from Samsungâs support page, but the âDIRECT-SMARTREFâ WiFi connection didnât work as expected. I kept getting a 04-100 error, and the troubleshooting steps didnât resolve the issue. Ugh, frustrating! 
The Solution:
After some research and trial and error, I found a workaround. Hereâs what I did:
- Ensure the Right App: Make sure youâre using the latest version of the SmartThings app. Older versions might not support all devices.
- Manual Setup: Instead of relying on the direct connection method, I manually added the refrigerator in the SmartThings app under âAdd Deviceâ > âBy Device Typeâ > âRefrigeratorâ > âSamsungâ.
- Follow the Steps Carefully: I opened the fridge door, pressed the Door Alarm button to unlock the temperature controls, and then pressed the Fridge button until âAPâ appeared. This put the fridge into pairing mode.
- Connect via WiFi: Once the fridge appeared in the app, I selected my WiFi network and entered the password. It connected without any issues this time!
The Outcome:
Now, I can control the fridgeâs temperature settings remotely, and itâs integrated seamlessly into my smart home ecosystem. Itâs amazing how this old fridge now works like a smart device! 
Tips for Others:
- If youâre having trouble with older models, try manual setup instead of direct connection.
- Make sure all firmware and apps are up to date.

I hope this helps someone else whoâs struggling with a similar issue. Happy smart home hacking!
