With the active P1 Splitter you can turn one P1 port into three P1 ports. For example, you can use a HomeWizard P1 Meter together with a charging station or other P1 devices.

Works with all smart meters and P1 devices.

The HomeWizard P1 Splitter creates 3 isolated P1 data signals. As a result, the P1 Meter works flawlessly and reliably with all car charging stations or other P1 devices, in contrast to regular splitters.

Built-in signal amplifiers.

The splitter can amplify incoming signals by up to 500% for a reliable connection. The amplifiers also make it possible to connect P1 devices at a long distance.

Flexible power supply.

The P1 Splitter can be supplied with power in different ways.

  • Smart meter: Via the P1 cable of a smart meter (SMR 5 or higher). No external power is required.
  • USB-C: An external power adapter (5V 1A).
  • P1 meter: On one of the ports via a HomeWizard P1 Meter with a USB connection.

See immediately if everything works.

Easily check whether your P1 port or P1 devices are working. The PWR LED shows that the splitter is working (orange) and whether the splitter amplifiers are on (green). You can see when connected devices request data and what the data frequency is of the p1 port (P1 IN). This way, on the splitter, you can see directly whether your connected devices and cables are functioning correctly.
