it has been a LOOOOONG time since I purchased the OpenSprinkler ver 2.2
I am having a difficult time finding updates and support for my device. Tons of information EVERYWHERE and old customer back after many new products. this is confusing.
Is there a page that has everything I need concerning the hardware version 2.2 device?
All up to date information is at: support.opensprinkler.com
Version 2.2 was discontinued a long time ago. The current firmware supports hardware 2.3, 3.0 and above, and OSPi.
