What is iHEMS?
Your home gets its own energy brain
iHEMS is an intelligent Home Energy Management System that reads electricity prices, weather data and your consumption pattern – and automatically distributes energy so you get the most out of every kWh.
Solar optimization
Prioritizes self-consumption of solar power and charges the battery when production is high.
Battery management
Charges when electricity is cheap, discharges when expensive – automatically and intelligently.
Heat pump control
Shifts heating to low-price hours without compromising comfort.
EV charging
Plans charging based on electricity prices and solar production – your car is ready when you need it.
In short
“iHEMS is the invisible conductor that makes all your energy assets play together – automatically, economically and comfortably.”
iHEMS requires compatible equipment. Not all features are available with all installations.

Get your energy analysis
Scenarios show typical snapshots. Your actual energy distribution depends on weather, consumption and equipment.
Peak load & grid balancing
Reduce your peak load – automatically
High peak loads cost extra and strain the grid. iHEMS distributes consumption intelligently so you avoid expensive peaks.
Automatic load distribution
iHEMS shifts flexible consumers like heat pump and EV away from peak load.
Lower grid tariff
Reduced peak load can mean lower capacity tariffs and grid connection costs.
Supports the grid
By smoothing your consumption, you contribute to a more stable and greener grid.

Questions & answers
What you might want to know
We answer the most common questions about intelligent energy management.
Is iHEMS only relevant if I have solar panels?
No. iHEMS also optimizes heat pump and EV charging based on electricity prices, even without solar. With solar panels, however, you get the greatest effect as the system can maximize self-consumption.
Does it reduce comfort by shifting loads?
No. iHEMS works within your comfort limits. The heat pump maintains your desired temperature, and your EV is always ready when you need it. Shifting happens during periods when you won’t notice.
Do I need battery storage from day one?
No. iHEMS can start by optimizing heat pump and EV charging alone. Battery can be added later and further increases the system’s value.
How much can actually be automated?
Up to 95% of daily energy decisions can be automated. iHEMS continuously monitors and adjusts based on electricity prices, weather data and your consumption pattern.
Is this only for tech-savvy users?
No. iHEMS is designed to run automatically. You don’t need to understand energy markets or technical details – the system handles it for you.
