HOBO® MX Gateway (MXGTW1) Manual

The HOBO MX Gateway provides near real-time data monitoring for most MX series loggers by
automatically uploading logged data to the HOBOlink® website. You can easily set up the
gateway with the HOBOmobile® app on your phone or tablet. Once configured, the gateway
uses Bluetooth® Low Energy (BLE) to regularly check for measurements from up to 100 loggers
within range. Logger measurements are then uploaded from the gateway via Ethernet or WiFi
to HOBOlink, where you can set up automatic email or text alarm notifications, display your
data in a dashboard, and export data for further analysis. Note: All MX loggers except the
MX100 series are supported by the gateway. Contact Onset Technical Support for questions on
MX100 logger compatibility with the gateway.

5. Configure the gateway.

a. If HOBOmobile is not already connected to the gateway,

tap Devices and then tap the gateway to connect to it.

b. Tap Configure.

MX series loggers must be configured to use them with the
gateway. If any of your loggers are already logging, you will
need to reconfigure them as described in the following
steps.

Note: MX100 series loggers are not supported by the
gateway. Contact Onset Technical Support for questions on
MX100 logger compatibility with the gateway.

To configure a logger for use with the gateway:

a. Tap Devices, and then Loggers at the top of the screen.

b. Tap the logger to connect to it and then tap Configure.

c. Make sure “from a Gateway” is checked under Upload

Data to HOBOlink.

d. Choose other logger settings keeping in mind the

following:

• A logging interval of 5 minutes or slower is optimal for
the gateway, although it can support a logging interval
down to 1 minute (see Viewing Data Uploaded from
the Gateway for details).

• If you select a logging interval faster than 1 minute, the
data logged at the faster rate will not be available for
the gateway to upload. Use HOBOmobile to read out

The gateway will regularly check loggers within range and
upload data to HOBOlink. See Viewing Data Uploaded from the
Gateway for details on working with data.

the logger and retrieve this data.

• Burst logging and statistics are not supported by the
gateway. Use HOBOmobile to read out the logger and
retrieve this data.

• For MX2200, MX2300, and MX2501 loggers, Bluetooth
is automatically enabled to ensure regular gateway
uploads can occur.

• The gateway uses Bluetooth Low Energy to
communicate over the air with loggers within range. If
MX2200 or MX2501 loggers or the top end of an
MX2001 logger is deployed in water, the gateway will
not be able to communicate with them.

• MX2200 loggers deployed in water must be out of the
water to communicate with

within range of your WiFi router (if using WiFi).

• The range for successful wireless communication between
the gateway and loggers is approximately 30.5 m (100 ft)
with full line-of-sight. If there are obstacles between the
gateway and the loggers, such as walls or metal objects,
the connection may be intermittent and the range
between loggers and the gateway will be decreased. Test
the range by positioning your phone or tablet where you
