Energy devices

Meter

Shows a live measurement of energy, water, or gas — and its history.

Each meter has a role set by your installer: grid (what you draw from and feed to the network), solar (production), battery, EV charger, consumer (a single appliance or circuit), water, or gas. The role decides how the meter is labelled and where it appears in the Energy section (see “Energy Overview”).

At a glance: name, the live reading with its unit.

Detail page — tap the device body:

  1. Period tabs — Now / Day / Week / Month / Year — switch the time window. The app remembers the tab you last used, per meter.
  2. History charts show consumption (or production) over the selected period.
  3. An energy balance card sums up today, this month, and this year.
  4. Depending on the meter's role, values are labelled as import/export (grid meters) or production (solar meters).
  5. Battery meters additionally show the battery's state of charge.

📘 Note: History charts need the history service, which your installer enables. Without it the live reading still works.

EV charger

Controls your electric-vehicle charger.

At a glance: name, a charge ring that fills while charging, and the state (connected, charging, or error).

Detail page:

  1. The charge ring shows the charging activity and current power.
  2. Start / Stop control the charging session.
  3. The charging current is set with a stepper and a slider, between 6 A and 32 A — lower it to charge gently (e.g. from solar), raise it to charge fast.
  4. The connection state shows whether a car is plugged in, and any error the charger reports.
  5. The last session card shows the energy delivered and the duration of the most recent charge.

Frequently Asked Questions

Why do meters appear in different Energy sections?

The installer assigns each meter a role, such as grid, solar, battery, consumer, water or gas. That role determines labels and placement.

Do live meter readings require history logging?

No. Live readings still work without the history service, but history charts require it.

How do I view consumption over time?

Open the meter’s detail page and choose Now, Day, Week, Month or Year. The app remembers the selected tab for that meter.

How do I control EV charging?

Open the charger detail page to start or stop a session and adjust the charging current using the slider or stepper.

Where can I see the previous charging session?

The last-session card shows the energy delivered and duration of the most recent charge.
