I currently have a wired home alarm system with magnetic door sensors, i would like to replace these with a ST door sensor so i can maintain the current alarm system plus integrate report to ST.
I am no expert at this so am seeking advice, i have seen various door sensors with terminal but believe these input terminals to allow connection of another switch, i believe i need and output to send a signal to my existing alarm system.
I want to minimise clutter on the door hence seeking a device that will serve both purposes, if it exists.
I am in the UK, so any suggestions will need to suit.
Not sure what kind of alarm system you have. But I have a DSC system and I monitor the keybus with a esp8266. Here is a link using a ardunio https://github.com/sjlouw/dsc-alarm-arduino
