Power Guard

Power Guard monitors your household power consumption in real-time using a HAN electricity meter and automatically controls devices when you approach your grid limit. It prevents costly peak penalties and tripped breakers by intelligently managing EV chargers, thermostats and other appliances. Supports Easee and Zaptec chargers, Easee Equalizer as a power meter, and all common HAN meters (Frient, Futurehome, Tibber Pulse, Aidon, Kaifa). Works with any thermostat brand. When power consumption gets too high, Power Guard steps in — reducing charger current, lowering thermostat temperatures or turning off devices in your chosen priority order. Once consumption drops to a safe level, everything is automatically restored. Set it up once and let it protect your home around the clock.

새로운 기능

버전 0.8.86 — Fix: Audi/Easee disco loop — after a completed charging session Easee retains offeredCurrent=6A internally; Power Guard no longer restarts a charger whose status is 'Completed' and power is below 200W. Fix: 'Charging complete' now only fires when Power Guard was actively controlling the session (guards against Easee falsely reporting Completed during a price-pause). Fix: HAN poll fallback no longer calls the mitigation engine with stale data — control is frozen until live HAN events resume. Fix: price state is now restored from cache on app restart so a charger paused for high price does not briefly start drawing before the first API fetch. New: Homey timeline notifications — Power Guard sends a notification when a charging session completes (✅), when charging is paused due to high price (⏸), and when charging resumes after a price pause (▶). New: 'Set active car' flow action — for households with two cars sharing one charger, use this action to tell Power Guard which car is plugged in (battery size + charge target). The override is valid for 48 hours. UI: charger status now shows 'Waiting for capacity' when there is not enough headroom to resume, and 'Waiting for cheap hour' when price control is holding the charger back.
