Edge-first
Local control > cloud dependency. Keep operating when connectivity, APIs, or forecasts degrade.
Energy, planned.
Deliberate energy planning and local execution.
Praxis creates a daily energy plan using forecasts, tariffs, and device state—then executes it across PV, battery storage, EV charging, and flexible loads. Edge-first, explainable, and fail-safe.
Plan → execute → adapt
Praxis coordinates your home as a system. It plans ahead, executes locally, and adapts in near-real time when conditions change.
- Praxis Plan: 24h rolling plan in 30‑minute bins, with 5‑minute adjustments.
- Energy orchestration: Coordinate PV, battery, and EV to maximize self-consumption and reduce peak imports.
- Edge-first control: Local decisions and safe fallbacks when data or devices are unavailable.
Phase 1 focus
Start with PV/battery/EV orchestration and a first specialized flexible load: pool systems.
Engineering-first by design
Praxis favors local control and clear reasoning. It’s infrastructure software: composed, precise, and resilient.
Explainable
Human-readable rationale for what will happen next—and why.
Fail-safe
Graceful degradation, manual override, and safe defaults when devices are unavailable.
Inputs
- PV forecast and weather
- Tariffs and peak windows
- Device state (battery SoC, EV schedule, load status)
Outputs
- Battery charge/discharge policy
- EV charging schedule
- Flexible load windows (starting with pool circulation)
Phase 1 scope (MVP)
Energy orchestration (Core)
- Build the Praxis Plan (24h rolling plan; 30‑min bins; 5‑min adjustments)
- Control PV/battery/EV to maximize self-consumption and reduce peak imports
- Run on-prem (Raspberry Pi 5) with Home Assistant integration
Success criteria
- ≥ 30% reduction in peak-period grid imports (vs baseline week)
- Battery cycle count reduced or maintained while meeting comfort targets
- Plan UI shows forecasts, SoC trajectory, EV schedule, pool windows, and rationale
Out of scope (Phase 1)
- Retailer VPP integration / market bidding
- Heat pump water heaters & HVAC control
- Multi-site orchestration
- Cloud-hosted optimisation
Praxis Pool (V1)
Pool systems are a high-impact flexible load: long run-times, clear constraints, and strong alignment with PV surplus.
Monitor
Track pH, ORP, temperature, and optional salinity—plus pump state and energy windows.
Control
Run a variable-speed pump to meet circulation and chemistry targets while aligning runtime to PV surplus and battery policy.
Fallbacks
Safe minimum circulation, device-offline behavior, and manual override when you need it.
