HAN and P1 are different output ports located on the smart meter inside your home. These ports provide real-time information about your electricity consumption to external devices, such as the Equalizer.

Your smart meter will normally have either a HAN-port or a P1-port, depending on where you are located. In general, the HAN-port is most common in Norway, while the P1-port is more common in Sweden and the Benelux region. Some countries use a mix of both. If you are unsure which port your meter has, we recommend contacting your energy provider.

Regional differences and compatibility

Across Europe, the type of output port varies depending on national standards, grid operators, and meter manufacturers. As a general guideline:

• Norway → HAN-port is standard

• Sweden → Primarily P1-port

• Netherlands & Belgium (Benelux) → P1-port is standard

• Denmark → Mix of HAN and P1

• Germany, France, and other countries → Mostly P1 but varies, often proprietary or without a standardized consumer port

In some cases, the physical port may appear identical, but the communication protocol differs, which can affect compatibility.

For this reason, the HAN Equalizer and the P1 Equalizer are two different products and are not interchangeable. These ports use different communication protocols and require different connector cables, and choosing the wrong Equalizer model will result in incompatibility.

How it works

The smart meter output provides real-time consumption data to the connected device, such as the Equalizer. The port is usually closed by default, meaning you will need to contact your grid owner to have it opened. If the port is not activated, the Equalizer will not function.

While both HAN and P1 provide the same type of data, they use different communication methods. The main difference is the physical connection: the HAN-port typically uses an RJ45 connection and requires a RJ45 to RJ12 cable, while the P1-port uses a standard RJ12 to RJ12 cable. The Equalizer itself connects via RJ12.

Verification and recommendations

Even within the same country, there may be differences depending on the grid operator, smart meter model, and installation year. You should therefore not rely solely on regional assumptions.

We strongly recommend verifying your setup by contacting your energy provider or grid operator, or by checking your meter documentation. You can also refer to our list of supported meters: 👉 Supported meters (HAN/P1)

Regional patterns can provide a useful indication, but there is no universal standard across Europe. Always confirm your specific setup to ensure compatibility and avoid installation issues.
