v2.3.0 — 🔋 Battery Time Remaining (time to full / empty)
🔋 NEW: Battery Time Remaining — see at a glance when your battery is full or empty!
PV Energy Management+ now estimates the remaining time of your battery — one of the most requested battery features, now built right in. A new "Time Remaining" sensor on your Battery device shows:
- ⏳ Discharging → time until empty
- ⚡ Charging → time until full
- 💤 Idle → "—"
Plus useful attributes: voraussichtlich_um (the clock time it will be full/empty), leistung_w, modus, quelle, and a human-readable dauer (e.g. "3h 20min").
Built honest, not jumpy
- Uses your real battery power for an accurate estimate (config: Battery Power Sensor).
- No battery power sensor? No problem — it can derive the value from the energy balance PV − house − grid (just point it at your grid power sensor).
- Smoothed (moving average) so the time doesn't flicker every second.
- Respects usable capacity / depth of discharge (new setting) so "time to empty" isn't overstated.
- Clean behaviour at idle / near-full / near-empty (no division-by-zero).
How to enable
Settings → Devices & Services → PV Energy Management+ → Configure → Battery, then set:
- Battery Power Sensor (W) — e.g. your inverter's
sensor.battery_power(recommended), and - Usable share (%) — your depth of discharge (e.g. 90%).
- If the direction is reversed, tick Flip sign.
The new sensor attaches to your existing Battery device — no new device, nothing to clean up. 🚀
