I just finished my build of the OpenSprinkler v2.1u and it was a great experience. Very well thought and quality product.
So far everything looks good during my “dry” tests with the exception that the contrast and the LCD back light need some adjustment.
I’ve seen some screen shots with those settings, but I don’t see them in my Options page. The firmware is ver. 2.0.3.
Do I miss something?
The LCD backlight and contrast are only available on the controller when you enter Setup Options (by holding button B3 while turning on the controller). These are not available on the web interface. You can check the user manual for details: http://rayshobby.net/?page_id=3775#setup
