Built a Lovelace card for the PoolLab integration (photometer-based pool water analysis: pH, chlorine, alkalinity, cyanuric acid...).

Requires the PoolLab integration: GitHub - dala318/python_poollab: Home Assistant integration and Python API for Pool Lab · GitHub — this card is a companion display layer on top of it.

Features:

  • Color-coded current value against your target range (green/orange), pulled automatically from the integration's ideal_low/ideal_high attributes

  • Previous 2 measurements shown with a trend arrow

  • Proper OVER handling (when a test result exceeds its measurable range)

  • Threshold cache in localStorage — keeps working even if a measurement arrives without configured targets

  • Multilingual: English, French, German, Spanish, Italian, Dutch, Portuguese

GitHub: GitHub - ADNPolymerase/poollab-card: Lovelace card for the PoolLab water analysis integration: latest readings, previous measurements, value colored against its target, OVER handling. · GitHub

HACS custom repo, store submission pending.

Feedback welcome, especially from non-English/French users on the translations.
