Also, all of my home switches (X,Y,Z,A) do it, I only used the Z to illustrate what was going on.
The vid just shows the LED on the diagnostics screen jittering, I jog the Z so the home is on, then off, then on. Then do the same while looking in the control box. There's no contacts, so they shouldnt be "dirty", and I am fairly certain that the voltage is sufficient. The last time I checked the switches were seeing ~13V which was about a month ago, but I will check again.
Thanks for the replies, they are giving me new ideas to investigate.
