fix: add 'device' param to Broadlink remote.send_command for HA 2026 compatibility

[gabrielcolceriu]

Problem

Starting with HA 2026 (confirmed on 2026.6.4), the native Broadlink integration requires a device parameter when calling remote.send_command. Without it, the following error appears in the logs:

homeassistant.components.broadlink.remote: Failed to call remote.send_command: You need to specify a device

This causes all IR commands sent via SmartIR + Broadlink to silently fail — no IR signal is emitted.

Root cause

BroadlinkController.send() in controller.py builds service_data without a device key:

service_data = {
    ATTR_ENTITY_ID: self._controller_data,
    'command': commands,
    'delay_secs': self._delay
}

The HA 2026 Broadlink remote.send_command handler now validates that a device is specified before processing raw b64: commands.

Fix

Add 'device': 'smartir' to service_data. The value is used only as a label by the Broadlink integration and does not affect the IR signal transmitted — raw b64: codes are passed directly to the hardware.

service_data = {
    ATTR_ENTITY_ID: self._controller_data,
    'command': commands,
    'device': 'smartir',
    'delay_secs': self._delay
}

Tested

• HA 2026.6.4
• Broadlink RM Pro (remote.rmpro_remote)
• SmartIR 1.18.1, device code 1060 (Samsung TV)
• Volume up/down confirmed working after fix
