Zaptec Sense is available in different versions, each designed for various types of electricity meters and connection ports. Compatibility depends on your meter’s type, available ports, and local standards. This guide will help you identify the right Zaptec Sense version for your meter and highlight any known exceptions or special installation notes.

Not all e-meters are relevant or available in every country. For local details, change the help centre language to your region.

Which Zaptec Sense version do I need?

Check your e-meter for available ports:

Zaptec Sense with HAN connectivity

For e-meters with HAN (RJ45) port (27 009 70) - typically AMS in Norway and Sweden

Requirements: 

• Physical HAN (RJ45) port on the e-meter.
• HAN (RJ45) port must be open before installation (contact your network owner).
• Meter protocol/push list: NVE (does not work with EFS).
• Good Wi-Fi signal strength (at least -75dBm).
• 2.4GHz network with WPA-2 password protection (does not work on Wi-Fi without a password).

Some network owners have meters configured for EFS, and Zaptec Sense HAN will not work with those. Always confirm with the network owner before installation. Many can switch protocols remotely if needed.

Supported e-meters (AMS)

Zaptec Sense support most e-meters that have an active HAN (RJ45) or P1 (RJ12) port and use the supported protocols.

Known deviations

• Kamstrup Omnipower (with RJ45 module):
  • Requires external power if Zaptec Sense has firmware version 5.4.8.3. The Kamstrup Omnipower e-meter doesn’t deliver enough power through the HAN port to keep Zaptec Sense charged. Use the micro USB port with a DIN-mounted power supply (e.g. HDR-15-5) or a power adapter. Without external power, the meter may restart or fail to supply enough data.
  • In later firmwares, an external power supply is only required during installation or software updates. A power bank can be used if a fixed power supply is difficult to install. But a permanent supply is always recommended.
• Aidon 6534:
  • No external power adapter needed. For IT 3-phase, L2 is not measured directly by this AMS type. Zaptec Sense estimates this value based on L1 and L3 readings, which are usually accurate but may lead to slight overestimations.
• Kaifa/Nuri:
  • Usually has a built-in HAN module. But the Kaifa model MA304T3 doesn't measure L2, as stated in its specifications. This type of AMS with external current measurement is less commonly used in private homes.

More details are available in the troubleshooting guide. 

Installation notes

Some meters (especially Kamstrup Omnipower) may not provide enough power. Use the micro USB port for an external supply if needed. A permanent power supply is recommended for stability.

Solar panel support

• Not recommended: The HAN (RJ45) protocol does not provide production data, so solar production may be registered as consumption. This can limit charging when the solar panels produce. Always check if the customer has or will install solar panels before deciding which power guard to install.

Zaptec Sense with P1 connectivity 

For e-meters with P1 (RJ12) port - common in Benelux, and some Nordic countries.

Requirements

• Physical RJ12 port on the electricity meter.
• P1 (RJ12) port must be open before installation (contact your network owner).
• Meter protocol must be DSMR 5.0.2 (Swedish standard).
• Power supply via the RJ12 port.
• Good Wi-Fi signal strength (at least -75dBm).
• 2.4GHz network with WPA-2 password protection (does not work on Wi-Fi without a password).

Supported e-meters (AMS)

Zaptec Sense support most e-meters that have an active HAN (RJ45) or P1 (RJ12) port and use the supported protocols.

Landis Gyr E360: Works with Zaptec Sense P1 in Denmark (Verified with N1 and Trefor). 

Known deviations

• Kamstrup Omnipower:
  • This e-meter does not provide enough power to charge Zaptec Sense's built-in capacitor.
  • Since the USB port in Zaptec Sense with P1 connectivity is not active, an external power supply cannot be used via this port.
  • For Zaptec Sense with P1 connectivity to work with Kamstrup Omnipower, an active P1 switch that provides power via the RJ12 port to Zaptec Sense is required. This accessory is available from some distributors and wholesalers, but not from Zaptec.
  • Other meters may also require external power, but this is most common with Kamstrup Omnipower.
• STAR (models 2MSZ302X, 2MSZ303X, 2MSZ310X, 2MSZ314X)
  • For other STAR models, contact our support and be sure to document which network owner and model number it concerns.
  • Some STAR electricity meters stop sending data on the P1 port after about 10 minutes.
• Dutch Smart Meter Requirements v5.0.2 is the standard that Energiföretagen Sverige points to as the industry standard (read more here) for the RJ12/P1 port. Electricity meters with the older version DSMR 4. x.x are not compatible. However, it is very rare to encounter this in Sweden.

Installation notes

As mentioned above, it is not possible to use the micro USB port to power Zaptec Sense. The USB port in Zaptec Sense with P1 connectivity is not active. If Zaptec Sense P1 is installed in an electricity meter that does not provide power in the port, an active P1 switch must be installed. This accessory is available from some distributors and wholesalers, but not from Zaptec.

How to install Zaptec Sense - P1 connectivity.

Solar panel support

• Solar panels are supported with Zaptec Sense with P1 connection. The P1 port (DSMR 5.0.2) provides production and consumption data. When production exceeds the house's total consumption, charging is maximised. This is then presented as negative values, and our system will then give full power to the charging station (limited by the charging station's fuse) because the main fuses risk tripping.
• If consumption exceeds production again, the power to the charging station is limited as needed, just as usual. This happens completely automatically without any settings. The advantage of this is that instead of seeing production as consumption, the system can utilise the extra capacity that solar panel production provides.

Zaptec Sense with RS485 Modbus + Ethernet connectivity

For installations without HAN or P1 port.

Requirements

• No HAN or P1 Port on the e-meter.
• The customer interface is not in accordance with industry recommendations.
• Measurement cannot/should not be done at or near the electricity meter.
• Good Wi-Fi signal strength (at least -75dBm).
• 2.4GHz network with WPA-2 password protection (does not work on Wi-Fi without a password).

Supported e-meters (sold in bundles) 

Zaptec Sense is available in bundles with the following e-meters. Choose the bundle that fits your installation needs. For each, follow the manufacturer’s instructions and refer to the installation manual for wiring diagrams.

• Carlo Gavazzi: 
  • EM112 DINAV01XS1X1 - 1 phase, 100A DIN inline
  • EM340 DINAV23XS1X - 3 phase, 65A DIN inline
  • EM111 DINAV51XS1X - 1 phase, DIN, CT
  • EM330 DINAV53HS1X - 3 phase, DIN, CT 

Installation notes

• Zaptec Sense (Modbus version) is installed with an external e-meter and communicates via Modbus.
• The package includes a cable for connection to the electricity meter. Measurement can be performed with current transformer clamps or by connecting directly to the meter's terminal.
• An external power supply is always required with this version, as Zaptec Sense does not receive power from the electricity meter. Use the micro USB port on Zaptec Sense (modbus version) with a suitable cable, either to a DIN-mounted PS (e.g. HDR-15-5) or a topower adapter.

FAQs

What if my meter isn't listed?

Zaptec Sense support all e-meters that meet the requirements for your Zaptec Sense version (HAN, P1, or Modbus). The list of meters in this guide only highlights those with known deviations or special installation notes.

If your meter is not listed it is generally supported (as long as it has the correct port, protocol, and power supply). 

If you are unsure or have a unique situation, please contact Zaptec support with your meter’s brand, model, and network owner for confirmation.

Do I need an external power supply?

• HAN: Sometimes, especially with Kamstrup Omnipower.
• P1: If the meter doesn’t provide power, an active P1 switch is needed.
• Zaptec Sense for installations without AMS: Always (included in bundle). 

Can I use Zaptec Sense with solar panels?

• HAN version: Not recommended. Solar production may be counted as consumption, which can limit charging.
• P1 version: Yes. Solar production and consumption are both measured.
