Hi there,
I've installed x7 2.5ers as a roller shutters but the last two are not working correctly, they behave in a funny way. They both respond to software commands but they don't through the 230v inputs, the strangest thing happens when I use my screwdriver (the one with a small light used for detecting the phase wire) on either the SW1 and SW2 because as soon as I do this test the Shelly takes it as a SW activation so the shutter starts moving.
What is going on here? Are those two shellys defective? Am I?
Thanks in advance.
