Hello!

I am experiencing an issue with my GHL controller, where I have set a pulse/pause interval to 00:00:01/00:01:00 on a smart switch based on readings from a pH sensor.

I have a CO2 solenoid valve regulator plugged into the corresponding smart switch.
The GHL is ignoring the set pulse pause interval and instead is supplying continuous power to the assigned outlet, thus duping CO2 into my system (the light also lights up, indicating power to the outlet). Thankfully, I was testing in an empty aquarium and not a populated one, because this dramatically dropped the pH. The solenoid functions normally.

I have swapped out the original power bar with another and experienced the same issue. So I believe there is an issue with the program or with the settings not registering.

I have used both a computer (PC, running Windows 11) with the GHL Control Center and the GHL Connect mobile app on my phone (Android) to adjust and save the settings.

Is there a way to get around this by utilizing the Gate functions (I am relatively new to the GHL and still learning)?

Has anyone else experienced this?
Thanks for your time and advice!

FIX UPDATE: Hello again. I eventually found a solution to this issue.
I required a firmware update, which I was unable to complete at work due to the lack of internet access. I took the GHL main computer home, updated it, and reset my required configurations at work. After this, I noticed that one of the options in the pH sensor settings was not set to Pulse/Pause. Once I corrected this, saved, and rebooted, the GHL was operating as intended.

Shout out to the GHL team! They have been super helpful with troubleshooting, especially Gaël.
