@CrackerStealth: as Samer said, in the latest firmware, we have explicitly disabled the ability to set any station to run indefinitely. My suggestion is to use the maximum t value (64800) and if needed have some way to periodically (every 18 hours or so) resend the command to renew it for another 18 hours.
@mpenzoh: seems OpenHAB and OpenSprinkler are both using the same port (8080) so they cannot both run at the same time. You need to change the HTTP port number on one of them.
