🚨 Order Alert Pro

An IoT siren system for WooCommerce stores. Instantly alert logistics staff when new orders arrive through remote WiFi control via the Blynk IoT platform.

Perfect for e-commerce fulfillment centers and warehouse operations - never miss an order again!

How It Works

Order Alert Pro connects your MicroPython-enabled device to WiFi and listens for triggers via Blynk's MQTT service. When a new WooCommerce order is placed, a request is sent to Blynk API that changes MQTT state and activates a relay-controlled siren in your logistics office, ensuring warehouse staff are immediately notified.

Quick Setup

Development Environment

python -m venv .venv
source .venv/bin/activate
make setup

Configure Your Device

Create config.toml with your WiFi and Blynk credentials.

Set your desired siren duration.

Connect relay to GPIO pin 5 (controls your siren/buzzer).

Production Build

make build    # Compile to .mpy files for better performance

Deploy

Create a WooCommerce script that triggers an HTTP query to Blynl on new orders.

Upload compiled files to siren controller.

Warning

Upload main.py, not main.mpy, as micropython does not execute compiled main on boot.
