Ultimeter

The Ultimeter driver operates the Ultimeter in Data Logger Mode, which results in sensor readings every 1/2 second or so.

The Ultimeter driver ignores the maximum, minimum, and average values recorded by the station.

Configuring with wee_device

The Ultimeter stations cannot be configured with the utility wee_device.

Station data

The following table shows which data are provided by the station hardware and which are calculated by WeeWX.
