P1 Output Port

The P1 Output Port (rj12) is located on the opposite side to the USB C port. It is plugged with a removable plug. Use this port to connect another p1 reader, note that external power is needed in this case as the power from the energy meter is not enough to drive two p1 meters.

Data Led

If there is no blinking of this light check that the p1 port on your energy meter is enabled. You usually need to contact your meter provider to enable the p1 port on your meter.

• hold for more than 5 seconds: The status led will start blinking fast, releasing the button now will reset the Zap. Resetting will clear the wifi credentials and require setting wifi using bluetooth in the Sourceful Energy App.
