Hi Product Hunt community! 👋 As an automation engineer, I’ve spent years working on factory floors and inside CNC shops. One major issue I constantly observed in small-to-medium manufacturing environments was the lack of simple, immediate machine monitoring. When a critical machine stops or an alarm triggers, maintenance teams often don't find out until significant downtime has already occurred. Rich SCADA systems are just too expensive and complex for a small shop. That is why we built **[Alertify.Online](https://alertify.online)**. We wanted to create a robust, plug-and-play hardware module that bridges the gap between legacy factory floor hardware and modern cloud communication. **What makes Alertify unique for industrial environments:** * **Versatile Voltage Range:** Native support for 9-36VDC digital inputs (perfectly covering standard 24V industrial control panels). * **Smart Input Logic:** Easily detects both NO (Normally Open) and NC (Normally Closed) signal switches to generate instant alerts. * **Network Protocol Integration:** Built-in capabilities to pull alarms via Siemens S7 Communication and Modbus TCP. * **Low Latency:** Industrial signals are pushed to maintenance personnel’s smartphones in milliseconds via our cloud infrastructure. To help the developer and automation community get started, we’ve also published an open repository containing configuration structures and JSON payloads: **[GitHub - Alertify Siemens S7](https://github.com)**. I’d love to hear your feedback, especially from hardware enthusiasts, IoT developers, and anyone managing manufacturing tech. What features or additional industrial protocols would you like to see integrated next? Thank you for your support! 🚀
