This project started with the idea of purchasing a cheap security system off one of the Chinese stores. After a little hunting, I found Digoo DG HOSA 433MHz 2G&GSM&WIFI Smart Home Security Alarm System Protective Shell Alert with APP which looked interesting so picked one up to tear apart. I was curious about how various communication methods were implemented. This is the first part of this adventure the next part will be exploring the firmware of the device.
