Thank you for replying to my call for help
Below the requested pictures, like I stated above; the same setup works with a normal Raspbian build, simple Python scripts and a cronjob but I wanted to make use of the awesome GUI Cayenne offers.
RaspberryPi Model B, PiHeader and a prefabricated rainbow cable connecting to the 8-port SRD-05VDC-SL-C relay module. It's currently powered by the 5V PIN, when I tried connecting to the 3.3V PIN the relay LEDs were very fade and IN8 was flashing contineouslty. Currently only 6 relays (IN1 to IN6) are connected.
Next, screenshots from the Dashboard as requested. Note that currently the Relay is set up as a General actuator but I tried the available relay widget before.
I'm available to provide more info if requested, I would really like to get this working.
