Zaptec Sense helps optimise energy usage when charging your EV. If you have a smart energy meter with an HAN port (RJ45), this guide will help you connect and activate Zaptec Sense for HAN connectivity.
This version of Zaptec Sense can be installed by both electricians and homeowners.
Don't have a HAN port?

1. Activating the HAN port
Before setup, make sure the HAN port on your energy meter is activated. The port is often deactivated by default, so contact your electricity provider to activate it. For more details, visit the NEK website.
Zaptec Sense complies with HAN-NVE push list.
2. Connect Zaptec Sense to the energy meter
Follow these steps to connect your Zaptec Sense:
- Locate the HAN port on your energy meter. This is an RJ45 port, similar to a network cable port.
-
Connect Zaptec Sense to the HAN port using the included communication cable.
- Wait 3 minutes for the device to start up (it will blink orange when ready).
If the HAN port is already in use by another device, you can use a Y-splitter. Just connect a regular 5vdc phone charger to the micro USB input on the Zaptec Sense.
3. Pair Zaptec Sense in the Zaptec app
- Open the Zaptec app and log in.
-
Go to Dashboard > Tap the three dots in the corner > Install Product.
- Scan the QR code on the device or user manual.

Follow the instructions to set the main fuse, confirm the meter connection, and connect to Wi-Fi.
-
If this is your first installation, select Pair with a charger and enter the charging station serial number.
The installation is complete when the light on Zaptec Sense turns solid white. The device will appear under your active add-on services in the app.
