ESP32 Forum

Hi, I have ESP32-C6, I would like to build a small home alarm on it, a few PIR sensors and a few contractors. My question is how best to do it, whether wired or I thought to use zigbee sensors and either write everything myself or use esphome or experienced clerks could advise me

If you're comfortable with programming and want to have more control over your system, you can choose to write the firmware yourself. This approach gives you complete customization and allows you to tailor the system to your specific needs. You can program the ESP32-C6 to handle sensor inputs, control contractors, and communicate with other devices or services.

Alternatively, you can use ESPHome, which is an open-source framework specifically designed for ESP8266 and ESP32 devices. ESPHome simplifies the process of configuring and managing ESP-based devices, including sensors and communication protocols. It provides a high-level abstraction layer, making it easier to integrate various components and set up automation. ESPHome supports both wired and wireless sensors, including Zigbee.

By the way, here is a home automation project with ESP32.

You can add more sensors and alarms to this project.

I'm thinking about using zigbe or 868mhz sensors with an additional radio module attached to the esp

Depends on how robust you want it to be. Using any form of wireless are the easiest to be bypassed. All you need to do is walk up to any ADT home with a transmitter that is higher power than what they use and there alarm system is bypassed. You don't even need to hack it cuz all their sensors are wireless.
