Broadlink | RM4C mini

Description

BroadLink RM4C mini is a compact IR blaster that lets you control IR devices like TVs, AV receivers, and air conditioners from your phone or Home Assistant. It connects over 2.4 GHz Wi-Fi and learns infrared codes so you can automate IR devices without their original remotes.

Overview

My Implementation

I use the RM4C mini to bring IR-only devices into Home Assistant for automations like power control, input switching, and timed shutoffs.

Home Assistant Integration

Integration Method: Broadlink (native)

  • Requirements: Device joined to Wi-Fi using the Broadlink app
  • Entities: Remote entity for IR/RF learn/send
  • Setup: Settings → Devices & Services → Add Integration → Broadlink
  • Notes: The integration supports RM4C mini and uses local polling

Practical Considerations

  • Line of sight: IR requires line-of-sight to devices (8–10 m typical range)
  • Power: Micro USB power required; adapter not included
  • Placement: Central placement improves IR coverage
  • Setup: Use the manufacturer app to onboard to Wi-Fi before HA
