WattBridge helps a household understand and orchestrate home energy flows across photovoltaic production, grid import/export, and controllable devices.
The first practical target is to connect an Enphase SunPower photovoltaic system with an Envoy S Metered EU gateway to Samsung appliances exposed through SmartThings.
Home energy systems often expose useful data through separate vendor apps and APIs. That fragmentation makes it hard to answer simple operational questions:
- Is there photovoltaic surplus right now?
- Which devices are consuming energy?
- Which appliance could safely run now?
- Did an automation recommend or trigger an action, and why?
- Can I check this and approve a recommendation while away from home?
- A technically comfortable homeowner operating a photovoltaic system.
- A household that wants recommendations first, and automation later.
- A maintainer who needs clear logs, predictable behavior, and recoverable local state.
- Documentation and explicit decisions before irreversible implementation.
- Adapter-based integrations instead of vendor assumptions in the core.
- Manual approval before automatic device control.
- Remote access through an explicit secure path, not accidental public exposure.
- Small milestones with test gates.
- Local-first operation where possible.
- Observability by default: logs, health checks, audit trails, and decision records.
WattBridge can read energy data from the photovoltaic system, read dryer state from SmartThings, normalize both into one model, and show a basic dashboard that is reachable away from home without sending real control commands automatically.
