Burglar alarm upgrade with esp8266
Posted: Tue Apr 11, 2017 12:10 pmHi all,
this is my first post in this forum and this is my first project with my "brand new" esp8266-12 dev board.
I would like to upgrade my wired 17 years old home burglar alarm system. I would like to send some email/text (SMS) on alarm status change(triggered/stopped).
So I start searching infos for this new system, and now I'm working on this beta version system.
Here following schematic diagram and LUA code. "Al" screw connector is +12V and it goes up when alarm relais is triggered (now I'm using perboard for testing),
init.lua
alarmtrigger.lua
trigger_alarm.php
I can't get var with pin name working inside functions, and something could be optimized.
Code is working, but it is ugly. Any suggestion will be appreciated.
Regards
b.
