Goal
Move water softener salt refill capture to an NFC sticker on the unit so the refill log is a reliable tap action instead of depending on chat phrasing.
Desired behavior
- Scanning the NFC sticker logs the standard refill event: 80 lb of salt added at the scan date/time.
- Home Assistant remains the structured source for salt-maintenance state and calculations.
- The water dashboard shows salt-maintenance status above the water usage chart.
- Chat/assistant retrieval can answer stats like last refill, days since refill, refill count, and average days between refills.
- Manual fallback phrase remains available:
Log 80 pounds of salt to the water softener.
- Bare or misspelled prompts like
Water Softner should return the desired logging phrase instead of creating a note.
Implementation notes
- Prefer a Home Assistant NFC/tag trigger or mobile app tag scan automation.
- Reuse the existing water softener salt maintenance helper/webhook path instead of creating a second data store.
- Keep recorder history focused on useful rollups and avoid storing noisy helper plumbing.
Acceptance criteria
- NFC scan creates exactly one 80 lb refill event with the current timestamp.
- Duplicate scans do not inflate totals unexpectedly.
- Dashboard shows last refill, days since refill, total logged, refill count, and average interval.
- Manual fallback phrase and help reply are covered by tests or a repeatable verification step.
