Triac commands not working

[MGLove]

I have a V4 HAT for the RPi. I am having trouble with a few Megabas commands, the Python megabas command to turn the 24 V off ,the command to test all 24v states and the Togle Triacs. I can get the "setTriac() " to work but will only turn on not off. Any ideas?
Thanks

Hi,
If you use the vard with DC power, the triacs will never turn off.
Please use AC power to be able to turn the triacs properly.

What is a Triac?​

Triacs are semiconductor devices that are widely used for switching medium power AC - their advantage is that they can switch both halves of alternating cycle.​
