Smartthings climate entity missing 'off' feature

[Cheiron1979]

The problem

Since updating to Home Assistant Core 2025.3.0, the thermostat card in Lovelace no longer displays the "off" mode icon. Previously, both "heat" and "off" icons were correctly displayed for climate entities that support these modes.

Now, only the "heat" icon appears, making it impossible to switch off the thermostat from the UI.

Expected behavior:

The thermostat card should display both "heat" and "off" mode icons if the entity supports them.

Actual behavior:

Only the "heat" mode icon is shown, even though "off" is listed in the entity’s hvac_modes.

Steps to reproduce:

1. Use a climate entity that supports both "heat" and "off" modes.

2. Add a thermostat card in Lovelace with the following YAML configuration:

type: thermostat
entity: climate.example_heater
features:

• type: climate-hvac-modes
  hvac_modes:
  • heat
  • "off"

3. Observe that only the "heat" icon appears, and the "off" mode is missing.

Additional information:

The issue was not present in Home Assistant Core 2025.2.x.

Confirmed on multiple devices and with different climate entities.

Restarting Home Assistant and clearing cache did not resolve the issue.
