Managing Custom Attributes

Custom attributes allow you to track user-defined attributes as part of the Device Details view.

When creating or editing a stored custom attribute you may specify a unit string for it. A valid unit string contains a list of unit names that meet the following criteria:

• Each unit name consists of a combination English letters and numbers, the percent symbol (%), or the Unicode symbols for degrees (°), degrees Celsius (℃), or degrees Fahrenheit (℉).
• Unit names must not start with a number
• Unit name may be followed by a caret (^) and an integer indicating the power the unit is raised to. For example “m^2” indicates square meters.
• The unit string may have one division character (/) between any pair of unit names.

The unit string may be prefixed with a real number, indicating a multiplier of the units.

Examples of valid unit strings:

• m/s – meters per second
• in^2 – square inches
• 0.1 inch tenths of an inch
• ft/s^2 – feet per second squared
• % - percent

Most common units will be recognized and converted to the preferred unit system for display. Arbitrary units can also be used, but will not be converted. For example:

• “m/s” will be recognized as being a metric set of units, and will be converted to “ft/s” or similar when the user has the Imperial units preferences set.
• “distanceUnits” is valid as a unit string, but will not be converted to a different set of units.
