Hi Jamal,
I'll need a little more information to properly help you.
How many batteries are you monitoring?
If you are only monitoring 6 batteries, make sure they are wired to the correct screw terminal and that they are facing the correct direction.
If you are monitoring more than 6, make sure you select "Both Devices" from the Device Selector drop-down menu.
If this a software issue?
What happens when you click the "Connect" button?
