am wondering if there was a bad connection somewhere. As they are all
working I will try to see if I can recreate the problem, but not sure I
will be able to. I'll get back to you if I discover anything further.
Thanks

at the sensors. So I am pretty confident it is not a wiring or power
supply problem.
Is there any way to determine if the simultaneous command is getting
