Output on/off not working with Bang-on Bang-off

I am attempting to build my first mycodo ph controller. The ph probe shows the current PH value in ‘live measurements,’ the ‘input,’ section of Mycodo, and also on my configured ‘dashboard’. I then configured two generic GPIO peristaltic pumps in the ‘Output’ section of Mycodo. From the output page I can turn on/off the pumps and I can do the same from the dashboard; this portion works without issue. I setup a bang-bang function to raise/lower the ph of the water with a .01 hyst targeted at 6.0. The function shows up in the Mycodo logs, but never turns on the pumps. Am I missing something?

The Bang-Bang (On/Off) Function only works with On/Off Outputs. Similarly, the Bang-Bang (PWM) only works with PWM Outputs. I just updated the docs to reflect this.

Hi Kyle I was going to attempt doing a similar thing. How do we control outputs such as PWM or uln2003 stepper motor?

Is there a suitable controller for uln2003 stepper motor output?
