v1.9.6 - ESP8266 Update Checker & OTA Improvements
Firmware version now reliably appears in Home Assistant on ESP8266. Update UI enabled on all platforms. OTA upload page shows real-time progress.
Stream-based Update Checker
- Replaced
getString() with direct JSON stream parsing (deserializeJson from HTTP stream)
- Avoids allocating ~10KB GitHub API response as String - critical for ESP8266 low-heap situations
- Increased BearSSL rx buffer from 512 to 1024 bytes for more reliable TLS
- Added
HTTP/1.0 mode to force Content-Length headers (no chunked transfer)
Update UI on ESP8266
- Update section now visible on ESP8266 web interface (was hidden since v1.8.0)
- Added extra polling timeouts (10s, 15s) for slower BearSSL HTTPS checks
- Dynamic release URL from API response
- Added
release_url and error fields to main /api/status endpoint
OTA Upload Progress
- Sync OTA page now uses XHR-based uploads with real-time progress bars
- Button disables during upload with "Do not interrupt!" warning
- Success/failure shown inline (no page reload)
- Removed PROGMEM success/fail HTML pages (saves flash)
