❓ Why use PiAlert?

---

Most of us don't know what's going on on our home network, but we want our family and data to be safe. Command-line tools are great, but the output can be hard to understand and action if you are not a network specialist.

PiAlert gives you peace of mind. Visualize and immediately report 📬 what is going on in your network - this is the first step to enhance your network security 🔐.

PiAlert combines several network and other scanning tools 🔍 with notifications 📧 into one user-friendly package 📦.

Set up a kill switch ☠ for your network via a smart plug with the available Home Assistant integration. Implement custom automations with the CSV device Exports 📤, Webhooks, or API endpoints features.

Extend the app if you want to create your own scanner Plugin and handle the results and notifications in PiAlert.

Looking forward to your contributions if you decide to share your work with the community ❤.
