Zaptec Sense optimises energy use for EV charging, making charging smarter and more efficient. If you have a smart energy meter with a HAN port (RJ45), this guide will help you set up Zaptec Sense for HAN connectivity. Both electricians and homeowners can install this version of Zaptec Sense.

If you don't have a smart meter or a HAN port, you can check out our other installation guides for different setups, such as Zaptec Sense – P1 connectivity or Zaptec Sense – RS485 Modbus and Ethernet connectivity.


Activating the HAN port

Before you can connect the Zaptec Sense - HAN connectivity, you'll need to make sure that the HAN port (on your energy meter) is activated. The HAN port is often deactivated by default, so contact your electricity provider to activate it. For more details, visit the NEK website.

  Note:

Zaptec Sense complies with HAN-NVE push list.

 


Step 1: Connect Zaptec Sense to the energy meter

Follow these steps to connect your Zaptec Sense: 

  1. Locate the HAN port on your energy meter. This is a RJ45 port, similar to a network cable port. 
  2. Connect Zaptec Sense to the HAN port using the included communication cable.
  3. Wait 3 minutes for the device to start up (it will blink orange when ready).

Installation and configuration 

  Tip:

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.

 


Step 2: Pair Zaptec Sense with the installation

Now, you'll pair your Zaptec Sense with the Zaptec app:

  1. Open the Zaptec app and log in. 
  2. Go to Dashboard > Tap the three dots in the corner > Install Product.
