For more information on the derivation of wave parameters, see the Spotter Bulk Wave Parameters PDF available on the support site.

Overview

<aside> 💡

A new CSV data format was introduced on February 1, 2025. Accounts created before this date can switch to the new format in display preferences. Switching to the new format is highly recommended, as it is faster to generate and allows downloading up to 6 months of data at a time. For Spotters not using full spectrum mode, the columns and data have not changed. For Spotters using full spectrum mode, see new column definitions below.

</aside>

The CSV will always have all columns present in its header row, but the columns with data actually populated depend on which sampling mode the Spotter was using at the time the sample was reported.

Common columns

These columns are used for samples in standard mode, and will also be present for Spotters in other modes.

Battery Voltage (V)

Battery voltage in Volts.

• Full battery: 3.8 - 4.1V, Mid level (25%-75%) capacity: 3.6-3.7, Low: 3.5, Critically low: 3.3V, Empty battery: 3.0V

Power (W)

Battery power in Watts.

Negative indicates the battery is supplying power to the system.

Positive indicates the solar system is recharging the battery.

Humidity (%rel)

Internal relative humidity %.

Sharp increases in absolute humidity (must account for temperature) may indicate a leak. If relative humidity exceeds 70%, recommend replacing desiccant.
