A timer can't see tomorrow. ChargeSync can.
A timer follows yesterday's rule. ChargeSync re-optimises around tomorrow's prices, weather and demand.

The kind of optimisation big energy sites use, working for your house
Big solar and battery sites have trading desks working them every half hour. Your home doesn't. ChargeSync brings that same intelligence down to the house, and this time the money stays with you, not the supplier.
Smarter energy is greener energy
By storing your solar and charging when the grid is cleanest, ChargeSync cuts your reliance on expensive, high-carbon peak power, so every optimised day lowers your bill and your carbon footprint.
Faster payback
By making your solar and battery work harder, ChargeSync shortens the payback time on your investment, your system earns its keep sooner.
Why ChargeSync is different
Home-first
We optimise for the owner's bill before anything else. Supplier-led platforms invert that; we don't.
Independent
We don't sell electricity. We don't sell batteries. We take no cut from any supplier or manufacturer, so nothing pulls our optimisation away from your bill. And if we don't save you more than we cost, your subscription pauses.
Whole-home
Battery, solar and tariff, and EV, heat pump and hot water, optimised together as one system.
Open
Hardware-agnostic by design, any tariff, any supplier. Works with , , and , actively integrating more, and honest about what we support.
Better than a timer
Re-optimises every 30 minutes against tomorrow's prices, weather and demand, not yesterday's rule. Half-hourly optimisation needs a time-of-use tariff to bite, anything from Economy 7 through to a fully half-hourly tariff like Octopus Agile; the finer your tariff's time pricing, the more ChargeSync saves.
