  • Smarter daily optimisation

    Automatically manages when energy is stored, used or exported.

  • More value from your system

    Helps unlock savings and flexibility earnings where eligible.

  • Clearer performance visibility

    Monitors the system to help spot issues and underperformance early.

The challenge

Solar and batteries are powerful, but hard to manage manually

Most households don't want to spend time checking tariffs, changing battery settings, deciding when to charge, when to export, or whether their system is performing properly. As energy tariffs and flexibility markets become more dynamic, the best outcome often depends on making the right decision at the right time.

  • Tariffs change throughout the day

  • Solar generation varies with the weather

  • Household usage is hard to predict

  • Batteries need the right charge and discharge strategy

The process

What happens behind the scenes

  1. System connection

    Lumo securely connects to supported solar, battery and home energy devices through existing device APIs.

  2. Understanding the home

    Lumo reads the system data, tariff information and energy patterns to understand how the home uses, stores and exports energy.

  3. Forecast what's coming

    Lumo uses solar, consumption and tariff information to plan when energy is likely to be most valuable.

  4. Optimise automatically

    Lumo manages battery charging, discharging and export decisions so the system can work harder without the homeowner constantly adjusting settings.

  5. Monitor performance

    Lumo tracks the system over time, helping identify connectivity issues, underperformance or unusual behaviour early.

A day in the life

A better daily plan for your customer's battery

Lumo looks ahead across the day and makes decisions based on expected solar generation, home usage and tariff prices. This helps the battery charge when energy is cheaper or abundant, discharge when it is more valuable, and export when there is an opportunity to create more value.

  • Charge smarter

    Stores energy when it is cheapest or most useful.

  • Customers use more of their own energy

    Helps reduce unnecessary grid import.

  • Export at better times

    Where possible, exports energy when it may be worth more.

The value stack

How Lumo creates value for the homeowner

Lumo's core value comes from making better day-to-day decisions around when the battery charges, discharges and exports. On top of this, eligible systems may also access additional earning opportunities through flexibility markets. Over time, performance monitoring can also help protect the value of the system by identifying issues early.

  • Standard solar & battery savings

Figures shown are illustrative. Actual savings and earnings depend on the household, system size, tariff, device compatibility and market eligibility.

Flexibility earnings

What are flexibility earnings?

As the UK electricity grid becomes more renewable, there are times when the grid needs households and devices to shift when they use, store or export energy. Eligible homes with batteries can help provide this flexibility. Lumo is designed to help suitable systems participate in these opportunities where available.

  • The grid needs flexibility

    More renewables means the grid needs better ways to balance supply and demand.

  • Your customer's battery can help

    A home battery can store, use or export energy at useful times.

  • Lumo manages the process

    Where eligible, Lumo helps coordinate participation without the homeowner needing to manage it manually.

  • No disruption to the homeowner

    Lumo's algorithms maximise the value we capture, while minimising any impact on how customers use energy day to day.

Ongoing monitoring

Keeping an eye on system performance

Even well-installed solar and battery systems can experience connectivity issues, underperformance or changes in behaviour over time. Lumo helps provide ongoing visibility so problems can be spotted earlier.

  • Connectivity checks

    Helps identify when devices stop sending data properly.

  • Performance visibility

    Tracks whether the system appears to be operating as expected.

  • Installer support

    Gives installers better information to support customers after installation.

Compatibility

Lumo works with your devices and utilities

Most manufacturers offer little or no optimisation. Those that do can usually only optimise within their own ecosystem. Lumo sits above the noise, connecting across devices, brands, tariffs and utilities to optimise the whole home energy system in the most valuable way.
