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.
