Z-wave reset

I have just remove location on my hub and all devices disappear. I was trying to connect them again but i am having some difficulty connecting the z-wave power plugs. From what i read I should exclude the plugs before I connect them again but i do not know how?
Any suggestion?

In the ST app, click on the More menu option, then click on the Hub is Online, then select Z-wave Utilites and choose General Device Exclusion.

works perfectly.

thank you
