Recently developed a small embedded device (using a nRF52840 microcontroller) that allows me to open my front gate remotely using my phone. I no longer have to carry around a gate remote. And my friends/guests can now open the gate from their phone as well. I couldn't find anything on the market for doing that so I'm glad I managed to do it (and it was a good opportunity to learn some embbedded programming and electronics).

- djsavvy 4y agoNeat! How did you reverse engineer the signal that your microcontroller had to send to the gate?
- olalonde 4y agoI got pretty far at decoding the signal with a RTL-SDR radio that I bought. It was a OOK code around 433mhz if I recall correctly. But I eventually abandoned that strategy as there was a simpler way to activate the gate through a direct electrical signal. So the device is just acts as a sort of switch now.

- landgenoot 4y agoI have an app to open the gate of my parking garage. However, apps are not that convenient while driving. Reverse engineered it and created an Android Auto app instead. https://daanmiddendorp.com/tech/2022/10/13/reverse-engineering-parking-app.html https://daanmiddendorp.com/tech/2022/10/13/reverse-engineeri...
- olalonde 4y agoVery nice. But I'm not sure my car has Android Auto, it is a bit old... I managed to integrate mine with Google Assistant on my phone so I say "Hey Google, turn on the front gate" (it thinks "front gate" is a switch).
