Wattring
Connects meters into energy communities.
Each smart meter is a node. Wattring closes the ring: real-time data from every meter, aggregated across the whole community — for Swiss vZEV and LEG.
How a ring works
Three layers — physical meters, the virtual ring, live insight for the community.
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.
Follow it live
Live dashboards and API: every member sees their own share and the community total in real time.
