Knowing the toggle is the key to use your charger!
From the Emporia app, tap home >> electric pump icon >> in the middle of the screen you see the toggle. When it’s gray, it’s in the PAUSED mode, no power will be sent from the EV Charger. When it’s blue, it’s in the READY mode, and it’s going to charge as soon as you plug into the vehicle (as long as the vehicle is ready to accept charge).
