Summon Button v1.0.0
First release. Flash `firmware-build17.bin` via the OTA Update tab in the web interface, or use `pio run --target upload` for the initial USB flash.
Features
- Emergency Pushover notification on button release with 30-second acknowledgment window
- LED feedback for all states (boot, summoning, ack, timeout, reboot warning)
- Persistent config in LittleFS — survives OTA firmware updates
- Web dashboard with live status, log viewer, config editor, and OTA upload
- Dead-man watchdog via healthchecks.io (5-minute ping)
- 6-hour heartbeat Pushover notification
- Factory reset button in web UI
- Battery monitor support (optional hardware, disabled by default)
- Debug mode keeps web portal always on
Notes
- Use the web OTA tab for all firmware updates after the initial USB flash — USB serial flash will erase the LittleFS config partition
- Configure Pushover credentials and watchdog URL via the Config tab in the web UI after first boot
