Aritech Alarm Internet Dialler

I too have been looking at the ESP platform... and have have some good success with porting the Aritech Keypad Emulator code over to the ESP32 Chip.

I'm using this little $9 open source board (D-duino-32) which has a tiny display built in... but any ESP32 should work.

Benefits of this over the Arduino, is as well as built in WiFi - is lots more space to implement better web pages and https connections.
It also has bluetooth built in which could have interesting possibilities...

Progress so far - Its connecting well to the Aritech 4 wire keypad bus and is updating the the keypads display to its little screen...



And by emulating a CD9038 Keypad this time - you will get a few more zones to use in the system
that can be triggered by things connected to the the ESP32...

Here is the Link to ESP32 ported code - the Aritech side works - and displays the Aritech RKP Display on the ESP's i2C LCD.

https://github.com/OzmoOzmo/CastleAritechArduinoESP32

It's there except for the Webserver side needs to be written (WebSocket::EtherPoll() in the file WebSocket.cpp).. That's the bit you want to provide yourself anyway - I'll post up the schematic later tonight - so let me know how you get on with it



Edit: I put up the schematics and a photo of the Arduino wiring at the above url - you can also see the Aritech RKP displaying on the ESP's display screen. Only a couple resistors had to be changed.

Well done Ozzo, looks good.
I did something similar 2 years ago with aritech 10 zone panel cs450 and has been working fine since
I Connected the 16 input/outputs through resistors into the  leonardo arduino inputs, Think they were 1k
eg:
int input0 = 0;  //D0 GREE Armed/UnArmed
int input1 = 1;  //D1 YELL Alarm
int input2 = 2;  //D2 BLUE P.A.
int input3 = 3;  //D3 ORNG FIRE
int input4 = 5;  //D5 RED  Internal Siren
int input5 = 7;  //D7 BLCK Ext Bell
int input6 = 10; //D10 WHT Doorbell
int input7 = 11 ; //D11 BRN OR testswitch for input0
int Led1  =  13;
int analog0 = A0; //A0 W/O Entry/exit
int analog1 = A1; //A1 O/W Hall+lounge
int analog2 = A2; //A2 W/B Cloak+Laundry
int analog3 = A3; //A3 B/W Patio+Kit
int analog4 = A4; //A4 W/G Bed123+enS
int analog5 = A5; //A5 G/W Bed4+Bath
int analog6 = A8; //D6 W/B PIR Hall+Kit
int analog7 = A9; //D8 B/W PIR Patio

When their values changed providing input 0 was low (armed) it sent an email from smtp.upcmail.ie to me@eircom.net.
This seemed to work fine for a week or 2 but then forgot to send them.

I then made it that everytime the hall door opened I got an email so that kept it awake.

I also bought 100 texts from txtlocal.co.uk for about £5,
so when outside bell goes on I get a text, showing which sensors are open at the time.
I also get an email showing every sensors state.

I prefer your system of just 6 wires, but my system only requires a resistor on the input.

I ran the ethernet to the panel, as wifi is only another thing to go wrong

For ease I got a piece of veroboard and mounted the pins on it backwards with a resistor on the inputs and the wiring on it. I nomorenails it to the alarm box with the pins sticking out so it is stationary and the ethernet shield just pushes onto it and the leonardo just pushes onto it.

Butchered a 1A usb car cigarette adaptor fed from 12v battery to power it up and grounded the negative.

I coded it so that led13 flashes like a strobe to show that it is alive and when sending an email it goes on for a second or 2. This made it easier to test.

In engineering mode / output test and i make output 0 low, I can go around the house and test the whole alarm, via eircom emails

Hi Ozmo,  for Home Automation, I use Raspberry Pi 3 with Google Assistant SDK.  For control of devices, I use IFTTT. It's all free of charge, and there's no subscription.  For example, "Hey Google, turn on the lights" will call a user-defined 'web hook' in IFTTT.  The web hook is just a URL to my php script (on an Apache website) running on my Rasp Pi.  And then in the php script, I can do any IOT thing that I want: lights, heating, music, etc, etc.   
I have an ESP32 controlling my immersion (a 30A relay controlling the boiler switch, and one DS18b20 thermometer taped to the side of the tank).  If I say "Hey Google, is there any hot water?", then my PHP script will check the temp of the water using a RESTful API call to the ESP32, and if it's not hot enough, then it will fire the relay to turn on the boiler.  It also creates a linux 'at' command (like cron) to turn off the boiler in 15 minutes.
My goal is to do the same thing for the alarm .. that's why I'm looking to setup a RESTful API interface instead of the browser UI.
Thanks.
Best regards,
Niall.
