Firmware and UI files update separately, so an old index.js can run against firmware that no longer returns secrets. It sends "" for the field it can't fill in, which cleared the WiFi passphrase (reboot into AP mode) or the MQTT password. The firmware now decides: "" keeps the stored secret, unless the same request changes the SSID or MQTT username, then it clears it (open network). /setNetwork compares the settings after applying them, so a kept passphrase no longer triggers a reboot. The UI cache-buster moves to 3.0.14d. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
