Smart Meter P1 Extender / Bridge / Splitter

The Smart Meter WiFi gateway with active P1 splitter offers all the benefits of the well known Smart Meter WiFi gateway, with an additional advantage.

The gateway features a second port that can function both as an “Active Splitter ” and in “Remote Gateway Mode.”

Sometimes the smart meter is not always located near the device you want to connect. If the distance is too great (usually more than 5 meters), the signal becomes weak and not all P1 messages will be received correctly. In that case, the smart meter gateway can be used as an extension cable or extender.

These Smart Meter Gateways can therefore be used, for example, to connect your Alfen charging station to your smart meter via the network. This makes it possible to use load balancing in virtually any situation.

Active splitter or Remote Gateway mode

The Smart Meter WiFi Gateway with an active splitter has a second port that can be used as a splitter or replicate data from another gateway.

  1. Active Splitter Mode: In this mode, the second port functions as an active splitter. The data received by the primary port is forwarded to the secondary port. This allows, for example, connecting another P1 device to the gateway so you can use both at the same time.

  2. Remote Gateway Mode: In this mode, the gateway can be connected to another smart meter gateway via the network. The data from the remote gateway is forwarded to the secondary port of this gateway. This is particularly useful if your smart meter is located in a different place, such as at the charging station for your electric car.

Connecting the Gateways

1. Connect the first Smart Meter Gateway to the P1 port of the smart meter and connect it to the WiFi network as described in the manual. It is recommended to assign a static IP address to this gateway. Remember this IP address.

2. Next, connect the Smart Meter Gateway with Active Splitter to the location where the P1 port is needed. Connect it to the WiFi network as described in the manual.

3. Now log in to the Smart Meter Gateway with Active Splitter. For this, browse to http://ip_address_gateway:82 and log in with username: admin and password: smartgateways. *Replace ip_address_gateway with the actual IP address of the gateway.

4. Now navigate to the Secondary Port Menu of the Gateway with Splitter:

The Secondary Port Menu is opened.

Enter the IP address of the first gateway in the “Remote Gateway IP” field. Then check the box next to “Enable Forwarding”. Click on “Submit new values” now.

This gateway will now connect to the Smart Meter Gateway connected to the smart meter and forward the data via the network to the second port (OUT).

5. Now connect the charging station to the OUT port of the gateway with active splitter.

The charging station will automatically recognize the smart meter and begin load balancing. The status of the connection between both gateways can be monitored through the Secondary Port Menu.

I already have something connected to my smart meter, can I continue using this device?

If there’s already a device connected to your meter, such as a another P1 WiFi meter, then you can continue using it. In that case, you will also need a Smart Meter WiFi Gateway with Active Splitter at the smart meter. Connect the existing device to the 2nd port.

What are the advantages of wirelessly extending the P1 connection?

The signal coming out of the P1 port of the smart meter is quite weak. For instance, if you use an extension cable to connect your electric vehicle charging station, it’s possible that due to resistance in the cable, the signal may not reach. By using the Smart Meter WiFi Gateways to transmit data via the network, you avoid this issue and ensure reliable data transmission. Another advantage is that you don’t need to lay cables.”
