Missing UI for Temperature Level Control in Matter Refrigerator and Freezer (Profile: TL)

[Mbadra96]

What is Wrong:

• For profile (TL), both refrigerator and freezer are configured with TemperatureLevelControl.
• However, no control UI is displayed for adjusting the temperature level for refrigerator (But works well for the freezer) in the SmartThings app.
• This affects the user experience as the temperature levels cannot be selected or modified through the app interface.

---

Steps to Reproduce:

1. Commission a refrigerator or freezer device with profile (TL) on the SmartThings app.
2. Open the device controls for TemperatureLevelControl.
3. Observe that no UI is available for selecting or modifying temperature levels.

---

Expected Behavior:

• The UI should provide a slider or selection control for TemperatureLevelControl to allow users to adjust temperature levels within the supported range.

---

Additional Information:

• Device Details:
  • Controller: ESP32-S3
  • Matter Version: 1.4
  • IDF Version: 5.2.3
• Logs:
  Attached below are logs from the ESP-Matter setup and exported JSON attributes from the SmartThings app showing the missing UI issue.

@Mbadra96
Thank you for checking the problem and contacting us. This is a problem caused by mismatching the settings between the profile and the device-configuration. I will solve it as soon as possible.

@HunsupJung Ok thank you

Hello,
The step attribute within the Temperature Control Cluster is read correctly by the CHIP stack as it should be 1 degrees but 0.1 degrees interval was assigned.
(as evidenced in the logs and feature map), but:
UI Rendering: The step value isn’t being displayed in the UI correctly it was set to (0.1 C)
JSON Export: The step field is not assigned correctly in the exported attributes JSON.
