Wattring
Schliesst Zähler zu Energiegemeinschaften zusammen.
Each smart meter is a node. Wattring closes the ring: aggregated metering, transparent allocation, real-time data, regulatory-grade billing for Swiss vZEV and LEG.
How a ring works
Three layers — physical meters, the virtual ring, regulated billing.
Connect meters
Plug in any wattling device or supported smart meter. Metering data streams in real time via MQTT.
Form the ring
Group meters into a virtual ring (vZEV/LEG). Wattring aggregates production, consumption and self-use.
Bill compliantly
Allocation per member, exports for tariffication, audit trail conform to StromVG / EnFV.
