Hello everyone! I recently connected my Samsung OCF Washer to the SmartThings app and have been exploring its capabilities. One thing I wanted to achieve was controlling the washer’s water temperature through the API, which led me on a bit of a journey. Here’s what I discovered and how I made it work!
First, I found that the washer supports the custom.washerWaterTemperature capability, which is a great starting point. However, figuring out the exact API request format was a bit tricky. After some digging and testing, I realized that the request body needs to include the desired temperature value in a specific JSON format.
For example, to set the water temperature to 40°C, the request body should look something like this:
{
“temperature”: 40
}
This sends the temperature value to the washer, and it adjusts accordingly. I also found that the washer accepts a range of temperatures, so you can customize it based on your needs.
If you’re using a service like IFTTT or a custom automation script, you can integrate this API request directly into your workflow. This opens up possibilities for scheduling wash cycles or adjusting settings based on specific conditions.
I’d love to hear from others who have experience with Samsung OCF Washer API integration. Have you tried any advanced automation setups or encountered any unique challenges? Share your insights and tips below—I’m sure we can all learn from each other!
Happy washing and happy automating!
