CloudWatcher Firmware v5.8.9

Required for user-upgraded units equipped with the sky-quality grade light sensor. Enables sky quality readings (mpsas) and activates support for the optional atmospheric pressure and relative humidity sensor. Only install if you have performed this hardware upgrade.

Hardware upgrade required
Legacy

Archived Software

This software is no longer required or actively maintained, but remains available for users who need it. The CloudWatcher now natively measures wind speed and relative humidity, making external weather station integration unnecessary.
Legacy — Not Required Since 2017

AAG WeatherCentre v2.3

Originally used to combine CloudWatcher data with readings from a standard weather station (Virtual Weather Station, Weather Display, or Cumulus). Now redundant as the CloudWatcher measures wind speed and humidity natively. Provided as-is, no longer updated.
