![]() Basic measurements on the zone with the door open and closed are as follows:Ĭan you provide some guidance as to how I'd tie into this circuit for a diy project to measure the door switch open and close for something like an ESP8266 or basic Arduino project? Is it as simple as measuring the voltage on the zone? I assume I'd have to get that down to the voltage logic for the ESP8266 or Arduino, but is it that simple? I'm not familiar with analog circuits? Do I need an isolator circuit of some sort or not an issue given its all low voltage? Thanks in advance for any guidance. My alarm panel is monitored so I don't want to screw that up or inject noise into the existing alarm system. However, I'd like to tie this into a door switch on my existing security alarm panel to use the existing sensor, cabling etc. I've currently been developing this only on a bench top. ![]() This means you have to open the window to expose the sensor, so if you dont turn off the system, the alarm may sound momentarily. In short, it sounds an remote chime and I get a SMS text when a magnetic door switch (reed switch) is opened. To do this, you have to hold the magnet as close to the stationary sensor as possible. I have a diy maker project using an ESP8266. ![]() I'm new to this forum but have a question I'd like to see if I can get some answers to and guidance on how to proceed.
