Hayward Monitor

Native macOS app (SwiftUI) to monitor and control a Hayward AquaRite / Sugar Valley NeoPool swimming-pool system — the same device managed by the PoolWatch / Vistapool iPhone apps.

Install

1. Download the latest .dmg from GitHub Releases.
2. Mount it and drag Hayward Monitor into /Applications.
3. Sign in with your PoolWatch / Vistapool account. Credentials go to the macOS Keychain — never to a file.

The app is Developer ID-signed, notarized by Apple, and updates itself via Hayward Monitor → Check for Updates… (Sparkle 2; checks are automatic, installs always ask first).

Requires macOS 14 (Sonoma) or later.

How it works

The Hayward Europe cloud is a Firebase project (hayward-europe). The app talks to it directly over REST — no Firebase SDK:

• Auth: Google Identity Toolkit (email/password of your PoolWatch account)
• Reads: Firestore REST (pools/{poolId} document)
• Writes: sendPoolCommand Cloud Function (WRP operation)

The API key embedded in the source is the vendor's public Firebase client key — the same one that ships inside the official apps; it identifies the project and grants nothing by itself.

Protocol reference: aioaquarite / fdebrus/hayward-ha. See ARCHITECTURE_EN.md (or the French version) for the full design.

Build from source

xcodegen generate
xcodebuild -scheme HaywardMonitor -configuration Debug build CODE_SIGNING_ALLOWED=NO

Requires macOS 14+, Xcode, xcodegen. Sparkle is resolved automatically via SPM.

Roadmap

• MVP: dashboard + controls + setpoints (v0.1.0)
• Real-account validation
• App icon, signed & notarized release DMG, Sparkle auto-update (v1.0.0)
• Menu bar extra
• Firestore real-time listen (replace polling)
• History charts & notifications
