Tomorrow is already planned.
amprex plans your home’s energy for the days ahead from the weather forecast, electricity prices, your network tariff and your household’s habits. It decides when the battery charges and when the heat pump runs, and adjusts the plan as the day unfolds. You keep the comfort you set. amprex keeps the bill down.

Tuesday’s plan for a house near Maribor
example · as planned Monday 22:00
Sun
Energy price
Network block
Battery
Heat pump
This is the plan the evening before; through the day amprex refines it as the real sun and use come in. A sunny afternoon is forecast, so the battery charges from the roof instead of the grid. The heat pump starts at 05:00 so the house is 21 °C by 06:00 without running into the expensive morning block. In the evening block the battery covers the house, so the grid draw stays under the contracted power.
What amprex does differently
Many energy managers move the battery around a price chart. amprex plans for the whole home, including the people in it.
Learns your rhythm
It knows when your home uses energy
From your own history it learns weekday and weekend habits, how much heating the house needs in this weather, and when the sun really reaches your roof. The forecasts improve every week, on the controller itself.
Smart battery
The battery is ready before you need it
Charged from the sun when the sun comes, topped up from the grid only when that is cheaper, held for the evening peak, and kept healthy with regular balancing cycles. A reserve stays in it for outages.
Dynamic prices
Every cheap quarter-hour counts
With a dynamic contract, amprex plans on the day-ahead market prices for your bidding zone, for any zone published on ENTSO-E, in 15-minute steps. When prices go negative it charges and heats instead of exporting at a loss. Fixed and time-of-use contracts work too.
Comfort per room
Warm where you are, saving where you are not
A weekly schedule and minimum temperature for each room, plus holds and away mode. amprex learns how fast your home warms up and starts heating early only once its predictions have proven right.
Shows its work
Every decision, in one sentence
“Heating paused: the house is 21.3 °C against a target of 21.1 °C.” And each day, what amprex saved you in euros compared with the same home without it.
Runs at home
No cloud in the control loop
Planning and control run on the controller at home. If the internet drops, it keeps following and adjusting its plan, using the last weather forecast until the connection returns. The app is a window, not the brain.
Built for capacity-based network tariffs · starting with Slovenia
Pay for less contracted power
The network charge (omrežnina) depends on your highest 15-minute draw in each of the five time blocks. One kettle, oven and heat pump starting together in block 1 can cost you for the whole month.
amprex follows every 15-minute window as it happens, keeps your draw under the power you contracted for each block, and charges the battery before the expensive blocks begin. That lets you choose lower contracted power with confidence. Time blocks and power limits are configurable, so the same approach works with other European network tariffs.

Questions
Do I need a dynamic electricity contract?
No. amprex saves on the network tariff and on your own solar with any contract. With a dynamic contract it can also use cheap and negative-price hours.
What happens if the internet goes down?
Your home keeps running. Planning and control happen on the controller; it keeps using the last weather forecast it received until the connection returns. Only the remote app is unavailable meanwhile.
Will my house get cold to save money?
No. Your comfort schedule and room minimums always come first; amprex only chooses when and how to reach them.
Who installs it?
Write to us with what you have installed and where you are; we will arrange installation with you. Installers who want to offer amprex are welcome to get in touch too.
Where is my data?
Your energy history stays on the controller in your home, and its keys and credentials are stored encrypted. The remote app connects to it over an encrypted connection.
