Home energy, made simple
Use your own sun first.
ems42 shows where your energy goes and what it costs. It tells you the best moment to run the dishwasher, charge the car or fill the battery, every morning and evening in your mailbox too.
No extra hardware needed: upload your Fluvius data, or connect your Loxone or Home Assistant.
Set up in four steps
-
1
Your home
Your postcode is enough. We never keep your address: only a location rounded to about 1 km, for the sun forecast.
-
2
Panels and battery
How many panels, which way they face, and your battery if you have one. No panels? ems42 helps you too.
-
3
Your contract
Dynamic, or fixed and variable. Know your price per kWh? Fill it in; otherwise we use average prices for Flanders.
-
4
Your data
Upload the quarter-hour values from Mijn Fluvius, or connect your Loxone Miniserver or Home Assistant for live values.
What ems42 does for you
Live power flow
Sun, house, grid and battery in one picture, updated every minute while you look. Also on a tablet on the wall.
The right moment
When to run the dishwasher, washing machine or dryer: on your spare sun, or in the cheapest hours with a dynamic contract.
Morning and evening email
In the morning the day ahead; in the evening how today went and when to use your own energy tonight and tomorrow.
Costs and capacity tariff
What your energy cost per month, and how your highest quarter-hour sets your capacity tariff.
Should I invest?
What a home battery, extra panels or a heat pump would do for your home, worked out with your own readings.
Gas and water too
If your meter passes them on, you see your gas and water use next to your electricity.
