System Requirements:

HOBOware 3.7.14 has some basic common System Requirements that are presented in the list below. If using HOBOware as the data collection server for a network of Indoor Wireless HOBO data nodes you may want to consider the configuration guidelines provided in the table. There are more detailed configuration recommendations available on the Onset Web site at

  High End Mid Range Low End Lowest End
CPU 2.9 GHz 2.0 GHz 1.8 GHz 1.8 GHz
  dual core dual core single core single core
RAM 3 GB 2 GB 1.5 GB 1 GB
Disk Space 256 MB+ (see note) 256 MB+ (see note) 256 MB+ (see note) 300 MB
User Model 4 3 2 1

The User Model row suggests some guidelines for using the Processor Speed and Memory table:

User Model 1 - Using HOBO Data loggers only, no data nodes - traditional desktop user
User Model 2 - Using HOBO Data loggers and up to 5 data nodes, 20 sensors
User Model 3 - Using HOBO Data loggers and up to 50 data nodes, 100 sensors
User Model 4 - Using HOBO Data loggers and up to 100 data nodes, 200 sensors

Disk Space – Defining the disk space requirements for HOBOware depends on the proposed use.   The table above describes the disk space needed for a traditional desktop user, allowing for installation of the program and storage of data files.  For users of HOBO data nodes, the space requirements depend on a variety of factors, including the number of nodes, the number of sensors, the frequency of data sampling, the longevity of deployments, and other factors.  Please see the FAQ on the Onset Web site for more details, at


HOBOware 3.7.13 is built with Java 1.7.0_71 on Windows and on OS X.  HOBOware no longer runs on Java 6.  Use of Java v1.4.x, Java 5 and Java 6 are specifically no longer supported.
