FAQs

The serial number and device key are found inside the door of the station. Keep track of these values as you will need them to register the device to your HOBOlink account.

You cannot stop regular connections to HOBOlink for a registered, powered station even if it is not logging. You can change to a slower connection interval in Readout Configuration. Unplug all power sources if you do not want it to connect to HOBOlink.

Yes. The graphs are displayed in the same order as the sensors are listed in the Conditions panel on the device overview page. Drag the sensors in the Conditions panel to the desired order and then the graphs will automatically be updated to the same order. Note that graphs must be enabled to appear on the page.

The Conditions panel shows the rain that fell in the last logging interval only. For example, if the logging interval is set to 1 minute and there wasn't a tip in the rain gauge bucket during that minute, then the rainfall shows as zero.

The channel count on the station for a manager module reflects the measurement channels and battery for all motes in the wireless sensor network. For example, if the network has one temperature mote, one soil moisture mote, and one temperature/RH mote, then the channel count reported on the station LCD would be 7: one for the temperature channel, one for the soil moisture channel, two for the temperature and RH channels plus three mote battery channels.

If the motes in your wireless sensor network have a poor connectivity rating or low signal strength, make sure there are no obstructions between the motes and that it is within communication range of the next mote. See Tips for Working with Wireless Sensors for monitoring network connectivity and adjusting mote positions.

If you do not see your MX Gateway in the list when you click Devices and then MX Devices, make sure you have set the HOBOlink settings in the HOBOconnect app, the gateway is powered up, and the network settings have been configured correctly. See Getting Started for details.

To ensure graphs can be viewed in HOBOlink without a delay, they are created at the time the device contacts HOBOlink. Therefore, graphs in the new units will be available after the next time the device connects.

Since graphs are created at the time the device connects, the new labels will not appear on the graphs until the next time the device connects to HOBOlink.

You must use HOBOware to configure an analog sensor port. Connect the device to a computer with HOBOware and select Manage U30 from the Device menu. Channels configured in HOBOware will appear in HOBOlink. See the HOBOware User's Guide for more details.

You must use HOBOware to set the default state of the relay in real time. While you can see the state of the relay and set up alarm conditions to trip the relay in HOBOlink, it does not allow real-time control of the relay.

HOBOlink is designed to be the primary software for the U30 Station. If you launched your device in HOBOware with different launch or readout settings than HOBOlink, the U30 Station will be relaunched the next time it connects to ensure it is configured to match the settings in the HOBOlink account.

You cannot stop a powered U30 Station from logging or connecting with HOBOlink as it is designed to run continuously without any user interaction. To stop logging and/or connecting to HOBOlink, unplug the battery. When you are ready for the device to begin logging again, you will likely need to select the Force Relaunch on Next Connection setting in Launch Configuration.

As soon as one system alarm trips on a U30 station, all system alarms are disabled. For example, let's say the Battery Low and Sensor Failure alarms have all been configured and the Battery Low alarm trips. The Sensor Failure alarms will then be disabled until the Battery Low alarm is resolved and you re-enable all system alarms.

If you change the launch description, logging interval, sampling interval, or select Force Relaunch on Next Connection, the device will relaunch automatically. If you only change the Full Readout Upon Power Reset setting, then the device will not be relaunched at the next connection.

If the device's memory fills in a time period that is less than the length between scheduled connections, some of the data will be overwritten in the device. This can happen on devices that have a full suite of sensors, are set to a 1-minute logging interval, and have a connection/readout interval of more than 24 hours. To avoid this problem, set the connection interval in Readout Configuration to less than 24 hours or increase the logging interval.

Because the battery is not a sensor and the dew point is a derived channel (temperature and RH data is needed to calculate the dew point), they do not have a presence in the header of the .dtf file. Therefore, there is no place to store those values for use in HOBOware. The labels for battery and dew point are saved in HOBOlink and only viewable there. Labels from all other channels are displayed in HOBOware when opening the downloaded .dtf file.
