One wired hub for multiple compatible Renogy devices
Bring supported RS485 and CAN equipment together before adding one BT-2 connection.
The Renogy RCM-HUB Communication Hub connects multiple compatible Renogy devices through RJ45 RS485 or CAN links and presents the supported system through a single BT-2 module. It reduces the need for a separate Bluetooth adapter on every compatible device.

RJ45 is the connector—not Ethernet
The hub's RJ45 ports carry Renogy RS485 or CAN communication. Do not connect the hub to an Ethernet network, router or incompatible device.
Why this Renogy product
Cleaner monitoring for a compatible multi-device system
Shared Bluetooth pathA single optional BT-2 can expose supported data from multiple connected Renogy devices.
Two protocolsThe hub supports documented RS485 and CAN communication paths with status LEDs indicating the active protocol.
Low overheadRenogy lists less than 0.35W operating consumption across a 9–60V input range.
System fit
Build the connection map from exact model compatibility.
Every connected device must support the correct Renogy RS485 or CAN protocol, port pinout and cable. Confirm topology, termination, firmware and maximum device count in the current compatibility documentation before installation.
Bluetooth separateThe communication hub is not itself the BT-2 radio. Add a compatible BT-2 module if app connectivity is required.
Cable cautionA generic network cable may have the right plug but the wrong pinout, shielding or application. Use Renogy-specified cables.

Common questions
Buyer FAQ
Does it include Bluetooth?
No. A compatible BT-2 module is separate.
Can I plug it into my router?
No. Its RJ45 ports are for Renogy RS485/CAN communication, not Ethernet.
Will it work with every Renogy product?
No. Each device must be listed as compatible and use the required protocol and cable.
Can it combine RS485 and CAN devices?
Renogy documents support for both protocols, but the exact topology and device combination must follow current compatibility guidance.
