How did you update the firmware to 2.1.5? If you did it in command line, there is possibility that you may have uploaded the wrong firmware. Also, when you say ‘none of the stations is actually on’ did you connect actual solenoids to the stations or did you just use a multimeter to measure the output voltage?
