Hey everyone, I’ve been working on setting up a smart security system for my home, and I thought I’d share my experience and some questions I have. I’ve always been a bit concerned about home security, so I decided to take matters into my own hands and create a system that would deter potential intruders without being too intrusive in my daily life.
I started by installing a motion sensor in my backyard. The idea was to trigger a sound when someone enters the area, giving them the impression that they’re being watched. I found an old MP3 player and connected it to a cheap amplifier. I recorded some angry dog barks and loaded them onto the MP3 player. So far, so good—no issues with the setup itself.
The next step was to manage the power supply for both the amplifier and the MP3 player. I wanted these devices to only turn on when needed, so I used a Fibaro FGS-221 relay module. I set up one relay to power the entire setup and another to power the MP3 player specifically. The challenge here was getting the MP3 player to start playing the recorded sound when triggered. The player requires a very short button press to start, so I needed the second relay to send a pulse of exactly 200 milliseconds. Unfortunately, the scenes I’ve tried so far can only handle pulses of at least one second, which is too long for my needs.
I’m wondering if there’s a way to generate a shorter pulse using the Fibaro relay or if there’s another device or method that could achieve this. I’ve heard about using custom scripts or maybe even a different type of relay, but I’m not entirely sure how to proceed. Any suggestions or experiences you’ve had with similar setups would be greatly appreciated!
This project has been a fun way to combine my love for DIY projects with improving my home’s security. It’s also been a great learning experience, even with the challenges I’ve faced. I’m excited to see if the community can help me overcome this final hurdle and make my system fully functional. Thanks in advance for any advice or insights you can share!
