SmartIR climate (1680 Mitsubishi Heavy) – fan modes work but swing / airflow direction not available in UI

[cowanmax]

Hello everyone,

I’m using SmartIR with a Broadlink RM4C Mini to control a Mitsubishi Heavy air conditioner (device code: 1680).

The integration is working correctly for the main functions:
HVAC modes: off, cool, heat, dry
Fan modes: low, med, high, auto
Temperature control: 18–30°C
IR commands are being sent successfully via Broadlink

However, I have an issue regarding airflow direction (swing / louver control):

Although the IR configuration (1680.json) appears to include airflow/swing-related commands, I cannot see or control swing/airflow direction from the Home Assistant UI. In the climate.ac entity state, I do not see any swing_mode or airflow direction attribute exposed. Only fan modes are available.

States:
hvac_modes: off, cool, heat, dry
min_temp: 18
max_temp: 30
target_temp_step: 1
fan_modes: low, med, high, auto
current_temperature: null
temperature: 18
fan_mode: low
last_on_operation: cool
device_code: 1680
manufacturer: Mitsubishi Heavy
supported_models: SRK25ZJ-S1, SRK13CRV-S1
supported_controller: Broadlink
commands_encoding: Base64
friendly_name: AC
supported_features: 393

But there is no option in UI or entity attributes for: swing mode for ex.
