+
+Shows the weights from a [FilamentScale](https://github.com/jelinj8/firmware-FilamentScale), a WiFi scale for up to five
+filament spools (ESP8266 with HX711 load cells; firmware, schematic, printed parts and build guide are in that repository),
+in a slim sidebar panel.
+
+* **Live weights** of all calibrated spools, pushed to every open browser.
+* **Save / Clear** a snapshot of the weights to see how much filament a print used.
+* **Settings** to show or hide each spool, rename it, tare it or set its current weight. Calibration stays in the
+  scale's own web interface, which the settings page links to.
+
+OctoPrint polls the scale's JSON API on your local network (every 2 s by default); the browser never talks to the scale
+directly, so the panel also works over remote access. The plugin uses no cloud services and sends nothing to the internet.
+The scale serves plain HTTP, as embedded devices on a local network usually do.
+
+## AI Development
+
+The code was written with Claude Code (Anthropic) under my direction: I specified the features, made the design
+decisions and tested every version on my own printer with the real scale. The plugin is therefore marked as
+`ai-developed` for transparency.
