Thought to share this and also in the hope to get some help on some points.
I use Domoticz to control lights and more in and around my house. The second step is to setup security so I can phase out my current security system.
Since I hate the pinpad I am making my system with a RFID reader which I can place everywhere or make multiple of them.
Its a struggle to create a decent entry and leave delay. When a token is scanned I want a 30 seconds delay before the alarm is activated. When entering (opening a door) I want a 30 seconds delay that gives me the time to scan a token before the alarm sounds. Anyone knows how to achieve this based on the status of the SecPannel?! (Due to maintainability i'm not willing to use lua scripts.)
How it works
I'm using a Particle Core as the controller. Its a small ARM Cortex M3 microcontroller with WiFi on-board. Completely configurable and flash-able trough web interface and connected to the cloud.
The Core has the following connected to it;
- - RC522 RFID module
- Quad Level-Shifter (3V to 5V)
- 2x WS2811 addressable leds
When a token is scanned the Core sends a webhook to the Particle cloud which on its turn creates a HTTP POST towards the Raspberry PI running Domoticz. On the Raspberry a web-server + PHP + MySQL forms the brains of the system.
The MySQL has several tables containing all known tokens, uses and cores. Also a table for logging and a table where token IDs are coupled to users.
The PHP scripts contain the logics which executes a particular action when a token is scanned. It for example sends a HTTP POST towards Domoticz to set the SecPannel.
When the system is armed and a intruder is detected by a PIR/Door or other sensor the GPIO switches a relay that sounds a alarm. Unless when someone enters trough a door and scans its token within 30 seconds.
User1 = out
User2 = in
User1 comes home and scans its token. Now User1 + User2 are in.
User2 go's away and scans its token. Now User1 + User2 our out. The PHP logically will give a callback on the scan and lets LED1 flash RED because the token is checked out. It also sends a HTTP POST to Domotcz to set the SecPannel on Armed.
Current project status
- - PHP code finisched
- Core code finisched
- Entry and leave delay. Not yet achieved. Seems to be difficult with Blockly
- Web frontend to manage users, tokens, cores and view log. Not yet started
