Homer — Energy Management

Control your energy

Homer's energy module monitors, analyzes, and optimizes your energy flows. From solar panels to heat pumps, from dynamic pricing to heat source management.

Pay less, use more, better understand what's happening in your home.

Lower costs

Automatically consume when electricity is cheap, feed back when it pays

Smart utilization

Get the most out of your solar panels, heat pump, or other sources

Grid balance

Contribute to a more stable grid by distributing consumption smartly

Professional power management

Beyond monitoring, Homer offers professional-grade tools for your electrical installation:

Distribution panel design

Design and document your electrical panel layout. Define circuits, breakers, and connections. Generate professional PDF reports for your installer or for your own records.

Load analysis

Understand how your circuits are loaded. Identify imbalances, potential overloads, and optimize the distribution of electrical loads across phases.

Tariff comparison

Compare energy tariffs from different providers based on your actual consumption data. No theoretical estimates — real numbers from your own usage.

Circuit health monitoring

Real-time monitoring of every circuit in your distribution panel. Track usage patterns, detect anomalies, and maintain a healthy electrical installation.

What you use it for

Research

Monitor and optimize specialized systems like biomeilers, generating valuable data for researchers.

The TEAPOTS project uses Homer to track and improve biomeiler performance.

Business

Optimize energy consumption for operations with multiple heat sources and dynamic contracts.

Automatically shifting consumption to cheap hours directly saves on the energy bill.

Residential

Integrate complex home systems: solar collector, heat pump, and wood stove working together.

Homer determines which heat source is most efficient at any given moment.

What Homer can do

Dynamic price optimization

Homer fetches energy prices from ENTSO-E and energy providers. The system:

Retrieves hourly prices from multiple sources
Determines optimal moments for consumption and feed-in
Switches devices automatically at the right times
Provides recommendations when automation isn't possible

For customers of dynamic providers like Greenchoice, this means direct savings.

Multiple heat sources

Homer excels at managing combined systems:

Solar collectors
Heat pumps
Wood or biomass heating
Biomeilers and other heat sources

Homer chooses which source runs when, based on availability, efficiency, and cost.

Energy flows made visible

See where your energy goes with clear visualizations. Where is it consumed, generated, and stored?

Automated control

Set your parameters and let Homer handle it. Or keep manual control with smart suggestions.

Remote monitoring

Keep an eye on your energy system and make adjustments from anywhere. Securely, through your own Homer.

Data and insights

What is tracked

Temperatures from all sensors
Energy consumption and patterns
Device status and run times
System performance

All stored locally on your own Homer, retained for 10 years by default.

What you can do with it

Compare efficiency of your heat sources
Calculate and predict savings
Plan maintenance based on performance
Discover improvement opportunities

Facts instead of assumptions. You decide what to do with them.

Integrations

Energy providers

Homer integrates with:

ENTSO-E: European day-ahead energy prices
Greenchoice/Eniris: Dynamic tariff information
Framework for additional providers

Data is efficiently cached — always current prices, minimal API traffic.

How it works

1

Fetch

Central server retrieves price data

2

Process

Data is processed and cached

3

Distribute

Homer servers periodically fetch updates

4

Optimize

Your Homer decides locally based on your own data
