First stable release of the Pool Chemistry integration for Home Assistant.

Features

• Water Balance Calculations

  • Calcium Saturation Index (CSI) - primary TFP methodology
  • Langelier Saturation Index (LSI) - traditional method
  • Water balance state (severely corrosive → balanced → severely scaling)
  • FC/CYA ratio with adequacy check

• Dosing Recommendations

  • Acid dosing (muriatic 14.5%-34.6%, dry acid)
  • Chlorine dosing (bleach 6%-12.5%, cal-hypo, dichlor, trichlor)
  • Alkalinity (sodium bicarbonate)
  • Calcium hardness
  • Cyanuric acid (stabilizer)
  • Salt (for saltwater pools)
  • Borates

• Flexible Entity Mapping

  • Works with any sensor source (IntelliCenter, LaMotte SpinTouch, ESPHome, MQTT, input helpers)
  • Auto-detects temperature units (°C/°F conversion)
  • Event-driven updates via state change listeners

• Configuration

  • Multi-step config flow with entity selection
  • Target chemistry values configurable via number entities
  • Chemical type selection (acid concentration, chlorine type)
  • Reconfiguration support for entity mapping changes
