Aggregated specification data confirms the RM4 Mini utilizes a Broadlink-developed Wi-Fi chipset optimized for 38kHz modulated infrared transmission. Technical analysis of the PCB reveals a 360-degree IR emitter array housed behind a signal-transparent polycarbonate shell. Performance metrics indicate the device supports a specialized HTS2 cable for integrated temperature and humidity monitoring via the Micro-USB port.
Technical documentation confirms the device is restricted to 2.4GHz Wi-Fi bands and does not include hardware for RF (433MHz) signal replication. Standardized testing protocols indicate that the Micro-USB power input is the primary mechanical interface. Operational data suggests that the device must be provisioned on a dedicated 2.4GHz SSID to ensure consistent network authentication in environments utilizing merged-band routers.
Hardware Capability Audit
The device includes a comprehensive onboard library of IR codes for HVAC and AV equipment. The internal architecture allows for local API access, provided the unit is not locked into a cloud-exclusive firmware state during initial commissioning.
If your infrastructure includes 433MHz motorized blinds or gates, the multi-protocol IR/RF hub provides a necessary hardware upgrade over this IR-only unit.
This hardware is a compact entry in the ir rf hubs category, focusing on line-of-sight signal bridging.
