Mesh Leaf Dual

Wireless load-management leaf node · one per managed stall

The Mesh Leaf Dual installs between the unit breaker panel and the managed loads — typically a Level 2 EV charger and a heat pump. It monitors the local feeder, receives current limits by mesh radio from the upstream Mesh Core, and enforces them locally so total building load stays inside the approved envelope. The resident's equipment operates normally.

Fail-safe by design

Throttles to a safe current if radio drops.

No internet required

Local mesh radio to the Core — no Wi-Fi or cellular.

Flexible-load ready

EV chargers today; heat pumps and other loads next.

System architecture

What you can count on

Fail-safe by design

If radio communication with the Core is lost, the Leaf falls back to a conservative configured current — never an unmanaged full-rate draw. CT readings are verified locally before the downstream load circuit is released.
