Why are Some LED grow lights not Controlled by the Controller?

Control Led Grow Lights

A friend uses a controller to control 70 lights in one road, but the 48th and 49th lights are not controlled by the controller. After he changed the driver, the controller was able to control the two lights, but after two or three months, they couldn’t control it again.

What is the reason?

According to our analysis, this may be a signal conflict between the network port board and the driver. It is necessary to make a good isolation design when designing. The ground wires of the main driver and the auxiliary driver should be independent and cannot be conducted. You can use a multimeter to test to see if the two can be connected.
