2.2—October 7, 2019

Cloud detection delay to avoid a single passing cloud closing the observatory. Smoother ambient temperature/humidity graph for units with an external RH sensor. Firmware update ability with no Windows PC needed. More configuration options (Pushbullet, Zeroconf, DNS). Trace of unsafe-detection events. Option to revert to an older software version.

2.1—August 15, 2018

Option to choose the ambient temperature source (RH or IR sensor). SMB2 protocol fix for a Windows 10 update issue.

1.9—March 14, 2018

Rain value logic changed from "greater than" to "greater than or equal". Mostly made version 1.8 official.

1.8—February 27, 2018
