⚖ Weight Sensor Calibration

Two-step calibration: first tare with nothing on the scale, then place a known weight and calibrate. Works over MQTT from anywhere.

Current Reading

-- g

Scale: --
Offset: --

Show 0 when reading is within ± g. Bigger values above this show exactly. Readings over 50 kg are ignored as bad reads.

Step 1 — Tare (zero with empty scale)

Remove all weight from the scale, then click Tare.

Step 2 — Calibrate with known weight

Place a known weight on the scale, enter its value in grams, then click Calibrate.

📡 Device Access — AP Mode

Start AP mode to add a new network from another device. The box stays connected to its current network while AP is active.

📷 ESP32-CAM

Status of the camera peer device + sensor tweaks. Status auto-updates every ~30 s.

☁ Photo Worker base URL (Cloudflare Worker + KV)

Preferred — delivery photos load from <worker>/photo/<file> via Cloudflare's HTTPS edge. The cam uploads each new snap to this URL automatically.

🌐 Cam tunnel URL (live stream + direct SD fetch — optional)

Optional fallback. Used for /stream (live MJPEG) and as the photo source if the Worker URL above isn't set. Only needed if you want internet-reachable live preview.

WiFi for the camera

The ESP32-CAM has its WiFi credentials baked into the firmware (currently Grace_5G). To switch networks, edit WIFI_SSID/WIFI_PASS in esp32-cam-firmware/src/main.cpp and re-flash. Full MQTT-driven WiFi management (like the main box has) is on the roadmap.

🔒 Lock Settings

How long the door-lock solenoid stays energised per unlock. Trim it to the shortest time that still reliably throws the bolt — shorter pulses run cooler and extend the solenoid's life. Accepts decimals for fine tuning.

Current lock pulse

New time (seconds)

Range 0.10–10.0 s. Applies to the front-door lock (the main gate keeps its own timing). Saved on the device; the built-in default is used until you change it.
