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.
