HomeWizard P1 Splitter | Connect 3 P1 Devices Simultaneously to Your Smart Meter

HomeWizard P1 Splitter | Triple P1 Port Extension with Active Amplification

Do you want to connect multiple smart devices to your digital energy meter at the same time? With the HomeWizard P1 Splitter, available at HomeWizard specialist slimhuisje.nl, you can expand the physical P1 connection of your smart meter to no fewer than three outputs. Instead of choosing which device gets access, you can now effortlessly connect a P1 meter, a smart charging station, and a heat pump or energy management system simultaneously. View our complete range of P1 energy meters to optimize your energy management setup.

1 IN to 3 OUT: Triple Port Extension for your Smart Meter

The HomeWizard P1 Splitter features a total of 4 RJ12 ports: 1 input port (IN) that connects to the smart meter via the included RJ12 cable, and 3 output ports (OUT) for your peripherals. This adds 2 extra P1 ports to your setup. While traditional passive splitters often suffer from data collisions or signal degradation when multiple devices are connected, this active P1 splitter guarantees a full-fledged and simultaneous data stream to all three connected systems.

Active Signal Amplification & Flexible Power Supply

Thanks to the integrated active signal amplifier (amplification of up to 500%), every connected device receives a fully isolated, strong, and clean P1 data signal. Live electricity and gas consumption data remain available instantly and without interference. With modern smart meters (SMR 5.0 and higher), the splitter is powered directly from the P1 port. Do you have an older smart meter (SMR 2, 3, or 4) that provides less power? Simply power the splitter via the integrated USB-C port with an external power adapter (5V 1A).

Ecosystems & Compatibility

• Home Assistant: Fully transparent operation within Home Assistant. All three connected P1 readers (such as a HomeWizard P1 Meter or an ESPHome reader) continue to send their data independently via their own integrations or MQTT.
• Homey Pro: Works seamlessly in any Homey Pro setup. The splitter acts as a reliable hardware bridge so that your Homey energy apps, charging station integrations, and dynamic rate controllers receive data simultaneously.
• SmartThings: Compatible with any hardware device linked with Samsung SmartThings. The splitter splits the physical signal without any changes to protocols or cloud connections.
• Tuya / Smart Life: Suitable for all Tuya-based P1 monitors. Both local P1 readers and cloud-connected devices receive their measurement data synchronously via the output ports.

Pro-Tip from slimhuisje.nl: Do you have an older smart meter (SMR 2, 3, or 4) or are you connecting devices that require extra power? Use the USB-C power port on the HomeWizard P1 Splitter. This ensures that not only the splitter is sufficiently powered, but that the connected P1 devices also receive a stable supply voltage!

Features & Physical Actions

• Triple P1 Output (1 IN, 3 OUT): Transforms 1 physical P1 connection into 3 full-fledged RJ12 outputs (2 extra ports).
• Active Signal Amplification: Prevents data buffering, interference, and signal loss between connected devices (up to 500% amplification).
• Universal Compatibility: Suitable for all Dutch and Belgian smart meters (DSMR & Fluvius).
• Plug & Play: No configuration or software settings required.
• Status LED indicators: See the PWR status (orange/green) and data activity of the ports at a glance.
• Support for External Power: Built-in USB-C port (5V 1A) for support with older meters.
• Compact Design: At only 75 × 35 × 25 mm, the splitter fits easily into any meter cupboard.

Package Contents

• 1x HomeWizard Active P1 Splitter (1x IN, 3x OUT)
• 1x RJ12 connection cable (15 cm)
• 1x Quick start guide

Note: An external USB-C power adapter and USB-C cable are not included. These are only required when used with older smart meters (SMR 2.2 to SMR 4.2) or when connected devices require additional power.

Technical specifications

Frequently Asked Questions (FAQ)

How many devices can I connect to the HomeWizard P1 Splitter?

The splitter has 1 input port (IN) for the smart meter and 3 output ports (OUT). This allows you to connect up to three different P1 devices (such as a P1 meter, charging station, and heat pump controller) simultaneously.

Why do I need an active P1 splitter instead of a passive Y-cable?

A passive Y-cable splits the signal without amplification, which leads to signal loss, data collisions, or stuttering measurements with two or three devices. The HomeWizard P1 Splitter actively amplifies and isolates the signal on all 3 output ports for an interference-free data stream.

Do I need an external USB-C power adapter for the P1 Splitter?

If your smart meter has SMR version 5.0 or higher (usually installed after 2014), the P1 port provides enough power and you do not need a USB adapter. For older meters (SMR 2, 3, or 4), an external USB-C adapter is recommended to ensure sufficient power.

What devices can I connect to the P1 Splitter?

You can connect almost any device that uses an RJ12 P1 connection. Think of the HomeWizard Wi-Fi P1 Meter, smart charging stations (such as Alfen, Wallbox, or EVBox), energy managers, heat pump controllers, or thermostat connections.

Does the HomeWizard P1 Splitter also work with other brands of P1 meters?

Yes, the HomeWizard P1 Splitter is completely brand-independent. It works excellently with HomeWizard devices, but just as well with P1 meters from Homey, CEMM, Enphase, YouLess, or self-built ESPHome solutions.
