About

Founded in 2024, ONEp1 is a private headquartered in Netherlands specializing in Solar, Energy Storage.

ONEp1 is a Netherlands-based company specializing in smart energy management hardware and software. The core product is the ONEp1 P1 Meter Splitter, a plug-and-play dongle that reads smart meter data via the P1 port (RJ12 connector) and intelligently distributes power information across four connected devices. The system enables EV chargers, home batteries, heat pumps, and inverters to work together without competing for solar power. Users can set device priorities, and ONEp1 adjusts the P1 data each device receives accordingly. The hardware is a one-time purchase with optional subscription features (€2/month or €20/year) for advanced cloud functions including customizable multiplexer settings, unlimited data history, Home Assistant integration, and dynamic price optimization. All data is stored on ONEp1's own GDPR-compliant servers in the Netherlands with strict user isolation and encryption. Installation requires no electrician—just RJ12 cables and WiFi setup via a web portal.
