P1SplitterKit splits 1 DSMR P1 port into 5 active, electrically isolated outputs. This allows you to connect multiple devices to the same smart meter simultaneously, without interference or data loss.
Ideal if you want to use a P1MeterKit, Home Assistant, DSMR Reader, HomeWizard, charging station, inverter or energy manager at the same time. No software or configuration needed: plug in, choose power source and you're done.
The splitter works with DSMR v2, v3, v4 and v5 smart meters in the Netherlands, Belgium and the rest of Europe. With DSMR v5, power can be supplied directly via the P1 port. For older meters, or when connecting multiple devices, you can simply use USB-C power.
Thanks to active signal amplification and electrical isolation per output, the signal remains stable and a fault on one device does not affect the other ports. Status LEDs immediately show whether data and power are active.
Developed in the Netherlands and built for reliable monitoring around the smart meter.
Need more than 5 outputs? You can use multiple P1SplitterKits in series thanks to the built-in signal amplification.

Find answers to the most frequently asked questions about the P1SplitterKit.
The P1SplitterKit is an active hardware-based splitter that divides your DSMR energy meter P1 port into 5 outputs. With electrical isolation and signal amplification, you can connect multiple monitoring devices simultaneously like a P1MeterKit, charging station monitoring, DSMR Reader, energy managers and Home Assistant setups without data loss or interference.
Yes, the P1SplitterKit is universally compatible with all DSMR v2, v3, v4 and v5 meters in the Netherlands, Belgium and the rest of Europe. The device works with all well-known brands such as Landis+Gyr, Kaifa, Kamstrup and Sagemcom. Simply insert the RJ12 cable from your energy meter into the input and connect your devices to the 5 outputs.
The P1SplitterKit has LED status indicators for each output. Each light blinks when data is being transmitted to the connected device. Additionally, there are separate lights that indicate whether the device is powered via the P1 port or via USB-C. This way you can immediately see if a connected device is correctly receiving data, without additional checks or apps.
Yes, the P1SplitterKit has flexible power options. With the slide switch on the side you can choose between power via the P1 port (for DSMR v5 meters) or external power via USB-C. For DSMR v5 meters, additional power is usually not needed. For DSMR v2, v3 or v4 meters or when using multiple devices, USB-C power is recommended.
No, the P1SplitterKit amplifies the signal and distributes it to all 5 outputs. Thanks to electrical isolation and signal amplification, all connected devices receive exactly the same reliable dataset, even with longer cables. There is no software that can affect the signal.
Electrical isolation means that each port works completely separate from the other ports. This has major advantages: if one device causes interference, the other devices will not notice. Your smart meter remains protected and each device gets its own safe, independent connection.
An active P1 splitter like the P1SplitterKit amplifies and isolates the signal per port, while a passive splitter is merely a Y-cable that weakens the signal. An active splitter prevents interference and conflicts between devices. Passive splitters often cause problems as soon as multiple devices read data simultaneously.
Yes, because the P1SplitterKit amplifies the signal, you can use longer cables without quality loss. This way you can place your devices exactly where you need them, even if that is further from the meter cabinet. This is a major advantage over passive splitters.
Yes, the P1SplitterKit works excellently with charging stations from all well-known brands such as Alfen, EVBox, Easee, Zaptec, Wallbox and Charge Amps. Many charging stations use P1 data for load balancing to prevent overloading your connection. With the P1SplitterKit this continues to work stably, even with other devices connected.
Yes, the P1SplitterKit supports connections with inverters from GoodWe, Huawei, SolarEdge, SMA, Growatt, Fronius and Enphase among others. This allows you to monitor both consumption and feed-in in one overview. Connect your inverter gateway and other monitoring devices simultaneously without conflicts.
The P1SplitterKit comes with a 1 meter RJ12 cable to get started right away. For additional devices you need extra RJ11 or RJ12 cables. Difference between RJ11 and RJ12: RJ11 has 4 pins/contacts (narrower), RJ12 has 6 pins/contacts (wider) and is standard for DSMR P1 ports. Most P1 monitoring devices come with the correct RJ12 cable.
The P1SplitterKit has 5 outputs, so you can connect a maximum of 5 devices simultaneously. This is more than most competitors offer (often only 2-4 ports). More than sufficient for Home Assistant, DSMR Reader, charging station monitoring, energy managers, inverter gateways and backup systems.
No, installation is plug & play and takes less than a minute. No configuration needed: 1) Connect the RJ12 cable from your energy meter to the input, 2) Connect your monitoring devices to the 5 outputs, 3) Choose power via the slide switch (P1 or USB-C). The LED lights immediately indicate if everything works correctly.
For more than 5 devices you can chain multiple P1SplitterKits in series, or use an output from the first splitter as input for a second splitter. This gives you additional outputs without signal quality loss thanks to the signal amplification.
Yes, the P1SplitterKit distributes the complete DSMR signal including all data such as electricity, gas, water (if available), temperature and other sensor data that your P1 meter outputs. All connected devices receive the same complete dataset.
Yes, the P1SplitterKit is fully compatible with DSMR and ESMR smart meters used throughout Europe. This includes meters from Landis+Gyr, Kamstrup, Sagemcom, Kaifa and other European manufacturers. Both Dutch, Belgian and other European smart meters are supported.
Yes, with dynamic energy contracts from providers like Tibber, EasyEnergy, ANWB Energie, Zonneplan or Frank Energie, real-time P1 data is crucial. The P1SplitterKit makes it possible to reliably have multiple apps and devices monitor your consumption simultaneously for optimal energy savings.
Yes, many heat pumps and boilers use P1 data to switch smartly and save energy. With the P1SplitterKit you connect these safely alongside other devices. Brands like Daikin, Mitsubishi, Samsung, Vaillant and Bosch that support P1 integration work seamlessly with the splitter.
Yes, all well-known WiFi P1 dongles and meters work seamlessly with the P1SplitterKit. This includes HomeWizard P1 Meter, Powerbaas, Iungo, SmartStuff and of course our own P1MeterKit. You can even connect multiple different P1 dongles simultaneously without interference or conflicts.
Yes, thanks to electrical isolation, your smart meter is fully protected against interference from connected devices. The P1SplitterKit electrically separates each device, so problems with one device can never affect your meter or other devices.
