TOPIC: Raspberry PI Server.

Raspberry PI 4 doesn't have GPIO 32 or GPIO 40 like in your project. It has pins with this number, but not GPIO. You have to setup GPIO.

I tired changing the PIN number to 18 and 20. But the same issue not able to set, reset or toggle the GPIO pins.
Can you suggest any pin number to be checked.

I don't know the reason of your problems. I can't check your scheme remotely. As you've seen in our video tutorial it works in our project. Some of our clients also had success in working with Raspberry PI projects.

Actually I tried your project also. But the PINS are not changing. One thing, Do I need to connect the output also to some relay board or is it okay.

You can use GPIO you want. It's not mandatory to use relays.

Now I am able to control the GPIO pins using TeslaSCADA. Actually earlier I was using Node red for logic building and GPIO control, may be it was interfering with teslascada.
My observation is that when the GPIO pins are triggered using Node red , it is not updated in TeslaSCADA.

TeslaSCADA can be used for HMI, but for logic building I have to used python or Node red. so how is it possible to use both, since the IO status is not updated in TeslaSCADA if triggered from other application like python or node red.
