gateway to attach it to the four clips on the mounting 
plate. 

 

Connecting to the Gateway 

To connect to the gateway with your phone, tablet, or device: 

1.

 

Tap Devices. 

2.

 

Tap the gateway in the list to connect to it. 

If the gateway does not appear in the list or if it is having 
trouble connecting, follow these tips: 

 

Make sure the gateway is within range of your mobile 

device or computer when connecting to it. If your mobile 
device or computer can connect to the gateway 
intermittently or loses its connection, move closer to the 
gateway, within sight if possible. Check the gateway signal 
strength icon in the app to make sure there is a strong 
signal between the mobile device or computer and the 
gateway. 

 

Change the orientation of your device to ensure the 

antenna is pointed toward the gateway (refer to your 
device’s manual for the antenna location). Obstacles 
between the antenna in the device and the gateway may 
result in intermittent connections. 

 

Wait a few minutes and then try to connect again. The 

gateway will not be displayed in the app when it is booting 
or when an automatic firmware upgrade is underway. 

 

If you recently powered up the gateway and the LED is 

continuously flashing, but the gateway is not displayed in 
the app, then disconnect the power from the gateway and 
plug it back in. The gateway should then appear in the app 
after it powers back up. 

Once your device is connected to the gateway, you can check 
how many loggers are in range and set up network 
configuration as described in 

Setting up the Gateway

. You can 

also tap 

 to check on gateway status:  

 

 indicates the gateway is running. 

 

 indicates the gateway is not configured. 

 

 indicates there is a problem with the gateway. Check 

the network settings. 

Monitoring the Gateway 

A heartbeat is regularly sent from the gateway to HOBOlink to 
make sure the gateway is still active. If no heartbeat is sent 
after 15 minutes, then the gateway status will change from OK 

to missing. The gateway will continue downloading the loggers 
even if it is not able to connect to HOBOlink. The data will be 
stored temporarily in the gateway and uploaded the next time 
it is able to connect to HOBOlink. 

To check the status of the gateway in HOBOlink, click Devices 
and then click MX Devices. Each gateway is listed by name and 
serial number with the status and the last time data was 
uploaded with the gateway. 

You can also set up an alarm to notify you via text or email 
when a gateway is missing or when the loggers that are being 
monitored by the gateway are missing, tripped an alarm, or 
have low batteries. 

To set up a gateway alarm: 

1.

 

In HOBOlink, click Devices and then click MX Devices. 

2.

 

Click Configure Gateway Alarms. 

3.

 

Click Add New Alarm. 

4.

 

Select a gateway. 

5.

 

Select the alarms you want to add for the gateway: 

 

Missing gateway.

 A gateway has not sent a heartbeat to 

HOBOlink for 15 minutes. 

 

Missing logger.

 A logger has not been found by the 

gateway for 30 minutes. 

 

Logger alarm.

 A logger being monitored by the gateway 

has tripped or cleared a sensor alarm. 

 

Logger low battery.

 A logger being monitored by the 

gateway has a low battery. 

6.

 

Select whether you want gateway alarm notifications sent 
via email or text. 

7.

 

Enter the email address or country code destination plus 
cell number. 

8.

 

Click Save Alarms. 

Viewing Data Uploaded from the Gateway 

A running gateway uses Bluetooth to regularly monitor loggers 
within range that have been configured for use with the 
gateway. New logger data received by the gateway is then 
uploaded via WiFi or Ethernet to HOBOlink every 5 minutes.  

To check when the latest data was uploaded, click Devices and 
then MX Devices. In the MX Devices table, look for the logger 
(by name, serial number, and/or model number) and check the 
last sensor reading listed. You can also see the date and time 
the logger was configured and which gateway uploaded the 
data. 

To view logger data uploaded to HOBOlink from the gateway: 

 

Set up a dashboard for real-time monitoring of the 
conditions where the logger is located. 

 

Export the data to a file. 

 

Set up a data delivery schedule so that uploaded data is 
automatically delivered to you via email or FTP on a 
schedule you specify. 

See the HOBOlink Help for details on how to set up a 
dashboard, export data, or create a data delivery schedule. 

Use these holes 
to attach the 
gateway to the 
clips on the 
mounting plate
