Data Loggers

zxweather works by having independent data logging services which are responsible for interfacing with weather station hardware, acquiring data and storing that data in a weather database. This page provides a brief overview of the data loggers included with zxweather.

Davis Logger

This is the data logger service for all supported Davis weather stations:

• Supports the:
  • Vantage Pro2
  • Vantage Vue
  • Weather Envoy.
• Supports optional extra sensors on wireless stations
• Optionally handles adjusting the consoles clock for daylight savings in regions where the console can't do this on its own.
• Can broadcast current conditions via either the database or a RabbitMQ message broker (useful for systems running on a Raspberry Pi)
• Redirects downloaded data to a log file should the database become unavailable for whatever reason

FineOffset WH1080 Logger

This should work with any weather station that uses the same memory layout as the FineOffset WH1080. It makes an effort to synchronise its reads with the wireless transmitters update schedule in order to avoid crashing the console.

This data logger is a little less "no maintenance required" than the Davis logger due to the poor design of the WH1080 USB interface so some special procedures are required after resetting the console. This is covered in the WH1080 Utilities Users Guide.

Image Logger

This service downloads snapshots via HTTP from an IP camera on a schedule and stores them in the weather database. It can be configured to start and stop taking photos based on calculated sunrise/sunset time or it can use the stations solar and UV sensors (if available) as a trigger to start and stop the schedule.

Time-Lapse Logger

This works in much the same way as the Image Logger but instead of saving each image to the database they're saved to a temporary location. At the end of the day these are assembled into a time-lapse video which is stored in the database.

Autosat

This program uses an RTL-SDR dongle, wxtoimg and a suitable antenna to download APT images broadcast by passing weather satellites. Its not been used in a few years and wxtoimg is apparently unsupported and unbuyable now so its possible autosat may not work anymore.
