How does Hub:One save me money?

Hub:One calculates your savings by comparing what you would have paid for your energy without our Automated Energy Manager (AEM), to your actual spend.

To do this, Hub:One first calculates how much you would have paid for grid energy when your solar generation could not meet your demand, as well as how much you would have been compensated for exporting excess solar, when it exceeded your demand. Subsequently, we compare these numbers to the 'actual' money you spent on grid energy as well as ‘actual’ compensation you received for exporting solar, while AEM was enabled and optimising your home (using Swarm’s data model, including solar forecast data). This means that our savings calculations assume that no existing (self-configured) schedules were running. At the same time, we take into account various other factors such as round-trip efficiency so we can ensure your savings are not being lost to electrical inefficiencies.

The difference between these values directly reflects the money that Hub:One has saved you as a result of its optimisation, on top of your existing solar installation.

Please note that any recurring subscription charges you may be paying are not subtracted from your cost savings totals.
