+# Environment variables:
+#   SENSOR_API_KEY  - API key for authentication (required)
+#   SENSOR_SERVER   - WebSocket server URL (default: ws://localhost:8080)

+# Examples:
+#   sensor-send growbox temperature 24.5
+#   sensor-send pump-1 pressure 1.2
+#
+# Dependencies:
+#   - websocat (install via: cargo install websocat)
