I have exactly the same problem discussed in this thread : https://www.ghielectronics.com/community/forum/topic?id=12385
I have a cerberus board with the latest firmware (i’ve also tried with an older firmware without more success).
I just want to control AC 250v lights and for example, i call EnableRelay(1).
the problem is sometimes (or often) the relays (sometimes all, sometimes few…) enter (with the help of some kind of magic) in the ON state.
I’ve tried to call EnableRelay or disableRelayin another thread, in the Program dispatcher, same result.
the mainboard is powered by usb.
the relay board is powered by dedicated 12V power supply.
Like in the previous thread, when i test the switching of the relays without having plugged anything on them, it works perfectly, but as soon as i plug my 250v AC led lights, the “strange behavior” occurs.
If it’s possible, i’m looking for a software solution without having to buy additionnal hardware…
Thanks for your help.
