7-day prices at a glance
Seven days of electricity prices for Austria hour by hour — mobile, no spreadsheets.
Benefit: spot cheap hours earlier and dodge expensive peaks.
Plant: solar & storage at a glance
Add your site and plant — Sparvo shows the solar week and helps plan storage and household use, not only the prices.
Benefit: use your own power first, grid only when needed.
Storage plan: charge, hold, conserve
See when grid charging makes sense, when to hold the battery, and why — prices and sun together, easy to follow.
Benefit: a clear plan instead of guesswork.
Plan devices & connection
Washer, EV, heat pump and more: pick devices — Sparvo suggests times. With a connection, control can run automatically.
Benefit: plan in the app, control with a connection.
A typical day
Morning price check → midday solar and laundry → evening or night charging when price and storage fit. Plan shows times; Plant shows the why.
Goal: avoid expensive hours, use your own power and storage wisely.
Share the household
The plant administrator invites co-users — or someone applies. Everyone sees the same plant and plan without duplicate setup.
Benefit: one truth for the family, clear roles.
