Why P1SplitterKit?
Most smart meters have only one P1 port, but you might want to connect multiple devices:
- P1MeterKit for Home Assistant integration
- WaterP1MeterKit for water + energy monitoring
- Solar inverter for production data
- DSMR Reader or other logging software
- Energy management system
The P1SplitterKit lets you connect up to 5 devices to a single P1 port without data loss.
Key Features
Hardware Signal Amplification
Unlike passive splitters, the P1SplitterKit actively amplifies the signal, ensuring reliable data transmission to all connected devices.
Flexible Power Options
- P1 Port Power: For a DSMR 5 meter with one device
- USB-C Power: For DSMR 4 and older meters, and from two connected devices
Visual Status Indicators
- Power LED: Confirms power source (P1 or USB-C)
- 5× Data LEDs: One per output, lights up when the device on that output requests data
Plug & Play
No configuration, no software, no WiFi setup: just connect and go.
