Home automation

The challenge owners face:

You've invested in a smart home. You can control every light, every thermostat, every device from your phone. But your energy contract hasn't kept up. If your home is reacting to commands rather than to costs, you're only using half of what you've built. The missing piece isn't more hardware. It's a tariff that actually thinks.

Problem

Smart home reacting to commands, not costs

Problem

Devices running on fixed schedules, not market windows 

Problem

No visibility on what's driving your energy bill

How it works for home automation owners

Your smart home already knows what to do. Now it knows when.

Connect 10s Energy to Your System

10s Energy integrates directly with Home Assistant — the hub at the centre of most serious home automation setups. If your devices are already connected there, linking them to real-time energy pricing takes minutes, not days.
  • Native Home Assistant integration
  • Compatible with KNX, Zigbee, Z-Wave and Wi-Fi devices
  • No new hardware or rewiring required

Set Rules Once, Let It Run

Define your preferences — which devices can shift, within what time window, down to what minimum charge or temperature. After that, 10s Energy watches the market and makes the calls automatically. Your home keeps running exactly as you expect. It just costs less to do it.
  • Fully customisable automation rules per device
  • Flexible time windows and override options
  • Priority logic — comfort always comes first

Real-Time Pricing, Real-Time Response

Elia's balancing market updates every 15 minutes. 10s Energy feeds those prices directly into your automations, so your home responds to the actual cost of electricity right now — not yesterday's forecast or last month's average. When prices spike, your system holds back. When they drop to zero, it acts.
  • Live Elia price feed, updated every 15 minutes
  • Automatic load shifting across all connected devices
  • Full savings dashboard with per-device visibility

A smart supplier that really means it

The market can do better

A home automation system is built on one idea: the right thing should happen at the right time, without you having to think about it. 10s Energy applies that same logic to your energy costs.

The Belgian grid produces different amounts of electricity every 15 minutes — more on sunny afternoons, more on windy nights, less during cold, still mornings. Those imbalances show up in real-time prices. Your home automation system is already capable of responding to them. With 10s Energy, it does exactly that. You built a smart home. We make sure the energy powering it is just as smart.

01. What is home automation and how does it work?

Home automation connects your devices—like lighting, heating, and appliances—so they can be controlled automatically or remotely. Instead of manual control, your home adjusts based on schedules, habits, or real-time needs.

02. Do I need a full smart home setup to get started?

No. You can start small—like with a single smart plug or thermostat—and build from there. Most systems are designed to scale as you go.

04. How difficult is it to set up home automation?

Most modern systems are surprisingly straightforward. Many devices are plug-and-play, with guided setup through an app. More advanced setups can be layered in later if needed.

05. What does 10s Energy actually do?

10s Energy helps you understand and optimize how energy is used in your home. It connects to your appliances and systems to give you clear insights, reduce unnecessary consumption, and improve overall efficiency—without adding complexity.

06. Do I need to change my existing setup to use 10s Energy?

No. 10s Energy is designed to work alongside your existing appliances and home setup. You don’t need to replace everything—most users start with what they already have and improve from there.

07. How quickly will I see results?

Most users start seeing insights immediately, with measurable improvements following as usage patterns are optimized. The biggest gains typically come within the first few weeks as inefficiencies are identified and reduced.

Since January 2023, part of your grid cost is based on your peak 15-minute draw each month — not just total consumption. The higher your simultaneous load, the higher your capacity tariff.

Not included in any figure above

Neither the standard dynamic nor the 10s Smart costs include the supplier's commercial margin. The fixed market reference already embeds a typical margin — the dynamic figures do not.

Belgian dynamic tariff providers typically charge €0.015–0.025/kWh above spot plus an annual fee of approximately €50–80/yr (Luminus: €0.021/kWh + €75/yr; Engie: spot × coefficient + fixed constant).
