Within the Hydrosys4 app Settings page in the actuators test section I can set the app to pulse the GPIO and I get the LED indicator on the relay board and the relay engagement but the relay does not disengage after the specified on period.
I have verified via the command line that I can turn on and off the relay board using the wiringpi GPIO interface library commands.
gpio mode 7 in turns off the relay and the command
gpio mode 7 out turns on the relay.
To reiterate my question: I can trigger via command line the relay to turn on and off but within the Hydrosys4 App I can get the relay to turn on but not off. I'm asking if anyone has any experience with Hydrosys4 and this issue of the relay NOT turning off? How did you fix this issue?
