Hi Guys, I have 4 wire nodes string, X nodes in and it stops working. However some times it must work for a few seconds or milliseconds and lights stay on above the nodes that are working and no not change until it works again for a few milliseconds. Which sort of indicates the data signal is having issues. I have swapped output cables from the control e.g. Move the issue string onto a different output, no difference. However tonight a colder night (few drops of rain), all the lights/nodes in the string are working find. The wires and square nodes are black so you can not see any of the inner working. Any thoughts on tools etc to use to solve the problem.
