1.1.0

HydroNode-Library 1.1.0

Existing devices must be reflashed once with this version — the backend replay window is now ±2 minutes and TLS roots rotated. After that, no reflash needed until at least 2035.

Security & reliability

• Bundled root CA set (Google Trust Services, ISRG, SSL.com) — survives Cloudflare Universal SSL certificate rotation without reflashing
• NTP sync before every send with retry; refuses to transmit with unsynced clock instead of sending a doomed request (backend replay window is ±2 min)
• System clock set from NTP so mbedTLS certificate validation works right after boot

API

• sendValue() now returns the HTTP status code or a negative error code (ERR_WIFI_DISCONNECTED, ERR_TIME_NOT_SYNCED, ERR_CONNECTION_FAILED) — build your own retry logic
• New connectWiFi(ssid, pass, timeoutMs) helper — optional, the library stays WiFi-agnostic
• New setDebug(Stream&) for diagnostics, setHttpTimeout(ms) for transport tuning
• NTP client is now a value member (no heap allocation in constructor)

Platform

• ESP32 only (declared via architectures=esp32 + compile-time guard). The library always used the ESP32 TLS API; ESP8266 never actually compiled.

Examples & docs

• Four complete, compile-tested examples: QuickStart, WiFiManagerSetup, ExternalWiFi, ActuatorControl
• README rewritten: API reference, WiFi strategy guide, security model, troubleshooting, rate-limit documentation (min. 9 s between submissions)
• keywords.txt for Arduino IDE syntax highlighting
