Per-circuit energy costs, accounting for solar and battery.

Corrente reads circuit-level usage from your Basis switchboard and factors in the solar and battery, for a clear picture of your energy costs.

Corrente's live energy view — solar, battery, grid, and home connected in an animated hub-and-spoke flow.
Why it's different

Costs calculated from real usage & generation.

Using the per-circuit usage the Basis switchboard provides, Corrente then allocates solar generation and battery output to each circuit so you get a better understanding of its cost, regardless of whether it's running on peak, shoulder, or off-peak power.

How circuit costs work →

  • Per-circuit usage straight from the Basis switchboard
  • Solar & battery allocated per circuit before working out what the grid actually charges
  • Retail plan rates across peak, shoulder, and off-peak
  • Export credits & amortised costs for solar and battery capital
E.G. one circuit, one day, at grid rates$8.55

On your bill$4.96

Solar & battery savings$3.58
What it does

Features

Home Dashboard

A live, animated diagram of power moving between solar, battery, grid, and home — with your switchboard summary and battery charge and state right below, plus a grid status indicator.

Energy History

Solar, home load, battery cycles, and grid import and export over time. Switch between hourly, daily, and monthly views, and step back through your history.

Energy Costs

A stacked view of exactly what makes up your spend — peak, shoulder, and off-peak tiers priced correctly, with what appears on your bill alongside the real cost.

Savings & Solar ROI

See the value your solar and battery deliver versus buying from the grid — and track your solar investment paying itself back over time.

Live Switchboard

Every circuit's power, voltage, current, and share of the load — with your own custom circuit labels, synced across the app.

Per-Circuit Detail

See which circuits use the most over any period and attribute real dollar cost down to individual circuits, with MCB, RCD, arc-fault, and temperature status in plain language.

Automations

Rules driven by schedules, battery levels, and free-power windows. Start from a template, then fine-tune triggers, conditions, and actions — automatically set your battery reserve and mode, or suspend and resume circuits.

Feedback & Notifications

Stay in the loop with notifications for what matters, and vote on what we build next.

Supported Sources

Corrente connects to the systems you already have — and more are on the way.

Tesla Powerwall

Live status, energy history, battery state of charge, and Storm Mode.

Basis Switchboard

Live circuit power, switchboard and subcircuit history, and your Basis retail plan.

In development

Sigenergy support is being built

Work has started on bringing Sigenergy systems into Corrente — live power, battery state, and the same per-circuit cost allocation the rest of the app runs on.

If you have a Sigenergy system and would like to help guide how it works, get in touch. Real installations and real feedback are what make the integration worth having.

What's next

Corrente is evolving fast. See what we're building, what's in progress, and what's planned — from new sources to deeper cost insights.

Your data stays yours

Corrente reads energy data only from the systems you connect, using each service's own sign-in. Your energy data is anonymised, tied only to your Corrente account — never sold, and never used for advertising.
