Leviton Load Center (Unofficial) — smart breaker monitoring, energy & control

Hi all :waving_hand:

I’m sharing a new app for Leviton Smart Load Centers: per-circuit energy monitoring and breaker
control for your electrical panel, natively in Homey.

:warning: This is an unofficial community app. It is not affiliated with, endorsed by, or supported
by Leviton. It uses the same private cloud service as the My Leviton mobile app, which means it
requires an internet connection and could stop working if Leviton changes their service.
Please keep that in mind before relying on it for anything critical.

What it does

  • Every smart breaker becomes a Homey device — live power (W), current (A), voltage (V), and
    lifetime energy (kWh), plus a detailed state (on / off / GFCI fault / arc fault / overload /
    short circuit / …).
  • Remote on/off for Gen 2 breakers, remote trip for Gen 1 and Gen 2, and a blink locate LED
    action so you can find the right breaker in the panel.
  • Trip alerts with the reason — a Flow trigger (filterable by cause: GFCI, AFCI, overload,
    short circuit…) plus an automatic timeline notification the moment anything trips.
  • Homey Energy done properly — the panel registers as your home’s cumulative main meter and
    every breaker/CT is an individual consumer, so the Energy tab shows total, per-circuit, and
    “other” usage automatically.
  • Threshold Flow triggers — power/current rose above or dropped below a value you set (great
    for “freezer stopped drawing power” or “workshop circuit at 80 % of its rating” alerts).
  • Bulk actions — all breakers on / off / trip-all, staggered to avoid inrush surges.
  • Whole-home extras — per-leg voltage/power/current/frequency on the panel device, CT clamp
    devices, Insights on everything.

What you need

  • A Homey Pro (the app opens an outbound WebSocket, so Homey Cloud is not supported)
  • A Leviton Smart Load Center with an LWHEM (2nd gen Whole-Home Energy Module) or LDATA
    (1st gen) hub, already set up and online in the My Leviton app
  • Your My Leviton account (2FA is supported; credentials go only to Leviton’s cloud and the
    session is stored only on your own Homey — no third parties, no telemetry)

Install

Good to know

  • Gen 1 breakers can be tripped remotely but not switched back on remotely — that’s a hardware
    limitation, not an app bug.
  • Leviton’s cloud closes connections hourly; the app reconnects automatically and also polls every
    2 minutes as a fallback, so brief gaps self-heal.
  • A read-only mode in app settings disables all control if you only want monitoring.
  • The app will never automatically re-close a faulted breaker — trips are a safety signal, and
    turning a faulted circuit back on is a decision for a human.

This app is a clean-room Node.js port of the excellent MIT-licensed Home Assistant integration by
gtxaspec (leviton-load-center /
aioleviton) — all the hard reverse-engineering is his
work. If you run Home Assistant, use the original!

Feedback, bug reports (app version + hub type + firmware please), and Flow ideas are very welcome —
