Most 'smart homes' are collections of disconnected apps that do nothing for the power bill. We treat the home as a controllable energy node: a Home Energy Management System (HEMS) that senses generation, storage state of charge, and load in real time, then dispatches devices against price signals and your comfort constraints.
Energy management as the control layer
The economic engine is time-of-use arbitrage and self-consumption. With granular submetering and 1-second telemetry, the HEMS knows precisely when solar is exporting at a low feed-in tariff versus when grid import is expensive. It pre-cools the home, charges the battery, and schedules the EV and water heater into low-price or high-solar windows, pushing self-consumption past 85% on a typical residential PV system.
Critically, this is closed-loop control, not timers. When a cloud bank cuts PV output, the system sheds deferrable load within 400 milliseconds rather than pulling an expensive peak from the grid—the same demand-management logic used in commercial buildings, applied at the meter.
Interoperability & local control
We standardize on Matter and Thread for device interoperability and run automation logic on a local controller, so core functions survive an internet outage and your usage data never depends on a vendor cloud. Open protocols mean you are never stranded when a manufacturer sunsets an app.
- Whole-home submetering with circuit-level load disaggregation
- Local-first controller running Matter/Thread—no cloud dependency for core logic
- Automated TOU arbitrage across battery, EV charger, HVAC, and water heating
- Solar self-consumption optimization with dynamic export curtailment
- Grid-services and demand-response participation where utility programs allow
Resilience & grid services
Paired with storage, the system delivers seamless islanding: on a grid fault it isolates and continues running prioritized circuits from the battery, then reverts when service returns. Where utilities offer demand-response or virtual-power-plant programs, the same controller bids your flexible capacity into the market, turning a cost center into a revenue stream.
Every decision is observable. The dashboard reports daily self-consumption, imported versus exported MWh, dollar savings against a no-automation baseline, and battery cycle count so degradation is tracked. The result is measurable: a 25-30% reduction in time-of-use electricity spend without compromising comfort.
