WMR300

A single WMR300 console supports 1 wind, 1 rain, 1 UV, and up to 8 temperature/humidity sensors.

The WMR300 sensors send at different rates:

WMR300 transmission periods

sensor	period
Wind	2.5 to 3 seconds
T/H	10 to 12 seconds
Rain	20 to 24 seconds

The console contains the pressure sensor. The console reports pressure every 15 minutes.

The station emits partial packets, which may confuse some online services.

The rain counter has a limit of 400 inches (10160 mm). The counter does not wrap around; it must be reset when it hits the limit, otherwise additional rain data will not be recorded.

The logger stores about 50,000 records. When the logger fills up, it stops recording data.

When WeeWX starts up it will attempt to download all records from the console since the last record in the archive database. This can take as much as couple of hours, depending on the number of records in the logger and the speed of the computer and disk.

Configuring with weectl device

The WMR300 stations cannot be configured with the utility weectl device.
