Requires node.js 20.0 or higher and Admin v5!

The protocol SIA DC-09 is used by alarm systems to communicate with the central stations by SIA-DCS, *SIA-DCS, ADM-CID and *ADM-CID.

This adapter is a SIA Server. When an alarm event is triggered, the alarm system sends over IP (TCP or UDP) the sia message to the central station.
The following ID Tokens are supported:

- SIA-DCS (SIA DCS),
- \*SIA DCS (SIA DCS encrypted),
- ADM-CID (Ademco Contact ID),
- \*ADM-CID (Ademco Contact ID encryted)

If use *SIA DCS (SIA DCS encrypted) or *ADM-CID (Ademco Contact ID encryted) you have to enable AES encrypting
and you have to enter a AES passwort in HEX format. The AES passwort has to be for AES-128 = 32 HEX characters, AES-192 = 48 HEX characters and for
AES-256 you have to enter 64 HEX characters.
An Example password for AES-128 would be: 3A1F6B8C9D4E7F20123456789ABCDEF0.

You can use ioBroker with this adapter as central station. For example. you can send a telegram message by ioBroker if you receive an alarm SIA messsage.

## Install & Configuration

1. Install the adapter
2. Configuration of the adapter:

Choose the IP-address and port for listening for SIA requests.
    ![sia_adapter1](https://raw.githubusercontent.com/schmupu/ioBroker.sia/master/admin/sia_adapter1.png)

Register account number. If you are using AES you have to enter a password (key). The key should be 16, 24 or 32 characters (byte) long.
    If the checkbox "AES password in Hex format" is active, the password length must be 32, 48 or 64 character (byte) long.
    In the field ACK timeout, you define how old the message can be in sec. If you define 0 sec., no timeout validation will be done.
    With the checkobx "Connection close by SIA Server", you can decide if the alarmsystem has to close the connection after it received the ACK message.
    If the checkbox "Connection close by SIA Server" ist disabled, the SIA server (ioBroker) waits 30 seconds for closing the connection by the alarmsystem.
    After this 30 seconds the SIA server (ioBroker) will close the connection.

3. Configure your burglar system to send SIA messages

![sia_lupusec1](https://raw.githubusercontent.com/schmupu/ioBroker.sia/master/admin/sia_lupusec1.png)
    - Lupusec XT1+/XT2/XT2+/XT3/XT4 (SIA-DCS):

Einstellungen -> Contact ID : ip:/subcriber@ip-address-iobroker:port/SIA
        Example: ip://A111F@192.168.20.55:55001/SIA

- Lupusec XT1+/XT2/XT2+/XT3/XT4 (\*SIA-DCS) encrypted:

Einstellungen -> Contact ID : ip://subcriber@ip-address-iobroker:port/SIA/KEY/(128,196 or 256 bits key in HEX)
        Example: ip://A222F@192.168.20.55:55001/SIA/KEY/3A1F6B8C9D4E7F20123456789ABCDEF0

- Lupusec XT1+/XT2/XT2+/XT3/XT4 (ADM-CID):

Einstellungen -> Contact ID : ip://subcriber@ip-address-iobroker:port/SIA
        Example: ip://A333F@192.168.20.55:55001/CID_SIA

- Lupusec XT1+/XT2/XT2+/XT3/XT4 (\*ADM-CID) encrypted:

Einstellungen -> Contact ID : ip://subcriber@ip-address-iobroker:port/CID_SIA/KEY/(128,196 or 256 bits key in HEX)
        Example: ip://A444F@192.168.20.55:55001/SIA/KEY/3A1F6B8C9D4E7F20123456789ABCDEF0

- Other alarm systems:

the Adapter will work with all alarm systems, which supports
        the SIA-DCS, *SIA-DCS, ADM-CID or *ADM-CID

4. SIA Objects / States

If you receive SIA messages, you see them in the states tree under the chanel accounts

![sia_adapter3](https://raw.githubusercontent.com/schmupu/ioBroker.sia/master/admin/sia_adapter3.png)

You see following object for every account:

| Object        | Description                                             |
    | ------------- | ------------------------------------------------------- |
    | accountnumber | Accountnumber (3-16 ASCII characters, "0"-"9", "A"-"F") |
    | crc           | CRC Checksum                                            |
    | extdata       | Extended data(ACII Data)                                |
    | id            | ID Token (example SIA-DCS)                              |
    | lpref         | Account prefix                                          |
    | msgdata       | Message data and it is always represented in ASCII      |
    | rpref         | Receiver number                                         |
    | sequence      | Sequence number                                         |
    | ts            | Timestamp (only included in encrypted messages)         |

Interessting is the object: msgdata (message data). Here you can see the thrown event of the alarm system. How to interpret the event, you have to ask your alarm system manufactor.

An example javascript in ioBroker to get an event:

```
    // example message: A444F|1401 02 001
    on({ id: 'sia.0.accounts.A444F.msgdata'/*A444F - Message Data*/ },  (obj) => {
        if(obj.state.ack === true) {
            const id = getState('sia.0.accounts.A444F.id'/*A444F - ID Token*/).val;
            if(id === 'ADM-CID' || id === '*ADM-CID') {
                const cid = parseMessage(obj.state.val);
                console.log(`Contact ID Message ${JSON.stringify(cid)}`);
                console.log(`Event: ${cid.event} for accountnumber ${cid.accountNumber}`);
            }
        }
    });
    ```

Output:

```
    Contact ID Message {"accountNumber":"A444F","qualifier":"1","event":"401","area":"02","zone":"001"}
    Event: 401 for accountnumber A444F
    ```

Event 401 means "Remote Arm/Disarm, when the system is armed or disarmed by SMS message or web access"

5. Bugs / Issues

If you have problems processing SIA messages or you found a bug, please create an issue.
    The issue should have following information:
    1. Manufacturer and type of alarm system
    2. The SIA message as a file. You can create a file if you activate it in the instance configuration.
    3. If you use encryption (AES), then I need the key to decrypt the message for testing.
    4. The debug output from ioBroker when processing the message
    5. Detailed description of the bug

After you have completed points 2 and 3, please change the AES key.
    You can test the saved SIA message using the following command

```
    # cat fileanme_of_sia_message | nc ip_address_of_iobroker sia_port
    cat /tmp/sia/sia_msg_20250201_202457309.txt | nc localhost 55001
    ```
