Hornet Nest Alarm Panel is the ultimate solution for integrating wired security systems into your smart home. Created with Home Assistant and ESPHome in mind, this PoE-enabled panel offers unprecedented flexibility, control, and ease of use for beginners and advanced users alike.

Designed for users looking to integrate their traditional wired alarm systems into their modern smart homes, the Hornet Nest Alarm Panel has a long list of features you’ll love. Whether you’re a smart home enthusiast, a DIYer, or a professional installer, this product offers a scalable and flexible solution to handle everything from motion sensors and door contacts to smoke detectors and alarms. With its 42 optoisolated zones, users can connect a wide array of devices and sensors, all while maintaining local control and monitoring through the ESPHome and Home Assistant ecosystems you already use.

A New Level of Security for Your Smart Home

Whether you’re looking to upgrade an existing wired alarm system or create a new smart home setup, the Hornet Nest Alarm Panel brings versatility and control to your fingertips:

Perimeter Security

Monitor door and window contacts to alert you if any are opened unexpectedly. It is ideal for protecting entrances and exits around your property.

Motion Detection

Connect traditional PIR motion sensors to the Hornet Nest Alarm Panel. When motion is detected in critical areas of your property, the alarms or automation in Home Assistant will be triggered.

Access Control

Integrate door or gate entry systems with the panel. Control access points by tracking the use of keypads, door strikes, or gate sensors and trigger actions such as unlocking doors or turning on lights upon entry.

Low Voltage Signal Detection

Incorporating the detection of a small 3-12 V DC signal into Home Assistant gives you the flexibility to monitor and automate various low-voltage systems in your smart home setup.

Smart Automation

Control garage doors, lights, or any other device in Home Assistant based on custom triggers.

Open Source

The Hornet Nest Alarm Panel is built with open-source principles, and we provide full access to its ESPHome YAML configuration and hardware schematics on our GitHub page. The project is licensed under the GNU General Public License (GPL) and the MIT License, ensuring openness and encouraging collaboration.

We’ve developed the Hornet Nest Alarm Panel using several open-source tools, including ESPHome for firmware, the wESP32 PoE board for power and networking, and KiCad for PCB design. By making these components open and accessible, the project invites the home automation and developer communities to explore, customize, and enhance the Panel to meet their specific needs.
