Hi Pete,
Thanks for the response. I have downloaded the firmware from this URL: http://www.raysfiles.com/ospi/ospi2.img.7z stated in this document (page 6): http://rayshobby.net/docs/ospi14_manual.pdf
it says “The latest version: OSPi SD Card Image 2 (with Unified Firmware, update 05/31/15) MD5SUM: edc2264a267d7330441855bafdb69dea”
When I go home, I can give you the exact firmware version. So if I am in the right version, OpenSprinkler is ready to be used with my setup? I was reading some of the threads today and came across one that suggested to use this plugin: https://github.com/KanyonKris/relay_board/wiki
Do I still need this plugin? Do I need to install the “Alternative Firmware: the sprinklers_pi Program” ? or the Unified Firmware is good?
Thanks again for helping me with this.
