COMMUNICATION
HUB
The Renogy Communication Hub allows you to connect multiple Renogy
appliances with an RJ45 port and RS485 communication protocol to just one
BT-2 Bluetooth module. Now you can use your phone to monitor multiple
devices at the same time! The Renogy Communication Hub also supports both
RS485 and CAN communication protocols – giving you a wider selection of
compatible devices.
Monitor multiple devices at the same time with a single Bluetooth module.

Operation
Connection
Connect the battery to the POWER port
of the HUB using the power cable;Press
the orange spring terminal, insert the
power cable,and connect it tightly.
Step 1
When connecting multiple Renogy devices to Bluetooth through the HUB for the first
time, each device needs to be connected to the HUB and registered on Renogy DC
Home App SEPARATELY. This process is used to assign an address to each device,
which is equivalent to registering an
''ID card''. After each device performs
data transmission, all devices can be
connected to the HUB and operate
together with the App. The "ID card"
won’t be affected by the power
failure, so this process is only needed
at the first connection.
04
Connect the BT-2 Bluetooth module to
the PRIMARY port of the HUB; Put the
switch at RS485.
Step 2
05
Connect one Renogy device to the
HUB; Register the device on the DC
Home App via BT-2 Bluetooth module.
Note：In this step, only one
SECONDARY port can be used to
connect to devices.
Take the Smart Lithium Battery as an
example. Use a communication cable
to connect the UP port of the battery to
any SECONDARY port of the HUB.
Open the Renogy DC Home app,
connect your phone/tablet with BT-2 via
Bluetooth. After successfully registering
the battery as a device on the App, you
can read the battery data on your
phone.
