System Functions

DaylightEvent

DaylightEvent(day)

Called at sunrise and sunset, according to the latitude and longitude values set in hsyco.ini, and the optional SunriseOffsetMinutes and SunsetOffsetMinutes parameters.

Parameters:

day: boolean - true at sunrise, false at sunset.

haActiveEvent

haActiveEvent(active)

Triggered by the change of state of an HSYCO server in a master/slave high availability configuration.

Parameters:

active: boolean - true if the server is active, false if not active.

PowerEvent

PowerEvent(power)

Triggered by a change of the current power load level, as set using the powerSet() Java API or the POWER action.

Thanks to this function, you can alter the power value shown in the Web interface, for example to aggregate power readings acquired from other sensors.

Parameters:

power: numeric - the power level, in Watts.

Returns:

numeric - if PowerEvent() returns -1 or doesn't return a value, HSYCO status is updated with the detected power value, the value returned by PowerEvent() is otherwise used.

The JavaScript PowerEvent function is always called, but its return value is used only when the Java PowerEvent callback is not defined or returned -1.

programTimerEvent

programTimerEvent(name)

Called when a program timer is activated.

Program timers are set using programTimerSet(), programTimerReset(), programTimerRepeat(), or using the corresponding actions in EVENTS.

Parameters:

name: string - program timer name.

SchedulerEvent

SchedulerEvent(groupname, schedulename)

This callback blocking function allows to call user methods at configurable intervals.

You define schedules using a group name and a schedule name.

Schedules under the same group run in the same thread and are executed sequentially, based on their interval in milliseconds. Schedules in different groups run in parallel.

Parameters:

groupname: string - the scheduler’s group name
schedulename: string - the scheduler’s name.

StartupEvent

StartupEvent()

Called only once when HSYCO starts, after the initialization and HTTP server start-up, but before the execution of the different field interface threads. It is not executed in a thread, it is therefore a blocking method, that must complete its execution before all other HSYCO services can be started.

SunPositionEvent

SunPositionEvent(azimuth, elevation)

Called when the Sun changes its height with respect to the horizon or its angle from true north.

Parameters:

azimuth: numeric - the current Sun angle from true north, in decimal degrees
elevation: numeric - the current Sun elevation in decimal degrees from the horizon. Elevation is negative at night.

TimeEvent

TimeEvent(time)

Called every 60 seconds.

HSYCO tries to synchronize the execution at the beginning of the minute, executing this method at seconds 0 of every minute.

However, the execution is not guaranteed. In case of heavy load HSYCO might not be able to execute the call with accurate timing. In extreme cases, it could occasionally skip some calls.

Parameters:

time: numeric - the current time in milliseconds.

varEvent

varEvent(name, value)

Triggered by the change of value of a program variable.

Parameters:

name: string - the variable name. Names are case-insensitive
value: string - the value to be assigned to the program variable.

Cameras

CameraCommandEvent

CameraCommandEvent(function, action, camera)

Triggered by a camera control input from the Web interface.

It can be used to execute arbitrary actions when the user clicks on the active areas of the camera view, or to replace some or all of the standard PTZ commands with custom actions.

Parameters:

function: string - see the table below
action: string - see the table below
camera: string - the camera name.

Returns:

numeric - if CameraCommandEvent() returns -1 or doesn't return a value, the standard PTZ command associated to the PTZ driver is skipped, otherwise it is executed normally.

The JavaScript CameraCommandEvent function is always called, but its return value is used only when the Java CameraCommandEvent callback is not defined or returned -1.

icon	function	action
	focus	far
	focus	near
	zoom	tele
	zoom	wide
	move	left
	move	right
	move	up
	move	down
	move	stop

CameraMotionEvent

CameraMotionEvent(event, time)

Called when HSYCO starts recording video from a camera.

Recording starts when a camera notifies a recording request with the recording HTTP API call (the zone=id portion is optional):

http://192.168.0.50/x/camerarec?camera=name&zone=id

Recording can also be triggered by the CameraRecTrigger() Java method or JavaScript function, or the CAMERAREC or CAMERARECFULL actions in EVENTS.

Parameters:

event: string - the event identification string, either the camera name only or name:id if recording is triggered by a camerarec HTTP call with the optional zone=id parameter
time: numeric - the current time in milliseconds.

CameraViewEvent

CameraViewEvent(camera, active)

CameraViewEvent() is called on changes of the live view status of cameras.

When at least one web client is showing the live feed from a camera, the camera is marked as active.

When no live feed request is received for a several consecutive seconds, the camera is marked as not active.

Parameters:

camera: string - the camera name
active: boolean - true if active, false if not.

DMX

DmxEvent

DmxEvent(channel, state)

Called after changes to DMX-512 channels.

Parameters:

channel: numeric - DMX channel address, from 1 to 512 which might be preceded by the DMX gateway number, starting from 0
state: numeric - the new channel value, from 0 to 255.

DmxFilter

DmxFilter(channel, state, reverse)

This function allows to filter the value of the status of each channel on the DMX-512 buses, sending to the gateway different values from those set in HSYCO.

This way, it is possible to apply chromatic corrections, or any on the fly translation of channels values.

This is a blocking function and is called when sending commands to the DMX gateway.

It is also called after reading current channels values from the gateway. In this case the conversion function should be symmetric and return a complementary value.

Parameters:

channel: numeric - the DMX channel address, from 1 to 512 which might be preceded by the DMX gateway number, starting from 0
state: numeric - the unfiltered value of the channel, from 0 to 255
reverse: boolean - false if called when writing to the gateway; true if called when reading from the gateway.

Returns:

numeric - the channel value that will be sent to the DMX gateway.

The JavaScript DmxFilter function is called only when the Java DmxFilter callback is not defined or returned the original value.

DmxStartupEvent

DmxStartupEvent(index)

Called when starting the monitor threads for each DMX bus, once per bus at the start of the execution of HSYCO, and also after every restart of the monitor thread, for example after communication errors.

It is safe, inside this function, to execute commands for the same DMX gateway.

This is a blocking function. The DMX driver will start after this function returns.

Parameters:

Index: numeric - number of the DMX bus, starting from 0.

Infrared Control

IREvent

IREvent(received, irtransid, event)

This function is called when an IRTrans receives or sends an IR command from its local IR database.

IRTrans can only receive and decode infrared commands that have been previously stored in its internal FLASH memory database.

Parameters:

received: boolean - true if the command has been received by the IRTrans, false if sent
irtransid: numeric - IRTrans number, starting from 0 for the first device, based on the listing order of the IRTrans parameter in hsyco.ini
event: string - the string of the command received or issued, formatted as: "remote_name,command".

I/O Servers

IOEvent

IOEvent(name, value)

Triggered by the value change of any data point of an I/O server.

Parameters:

id: string - the server id and the name of the data point. According to the type of server, the format changes but it generally appears as server name, as declared the ioServers parameter in hsyco.ini, followed by a specific name representing the data point within the system
value: string - the new value. For binary inputs or outputs, the returned values are “0” or “1”.

IOStartupEvent

IOStartupEvent(index)

Triggered by the start of the communication thread of each I/O server - once for each server at the beginning of the execution of HSYCO, and also after every reboot of the communication thread, for example after communication errors.

This is a blocking method. The I/O server driver will start after this function returns.

Parameters:

index: numeric - the I/O server number, starting from 0, based on the listing order of the ioServers parameter in hsyco.ini.

Modbus

For detailed information about the Modbus protocol, and the response PDU formats, you should refer to the MODBUS Application Protocol Specification V1.1b documentation at: http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf

ModbusEvent

ModbusEvent(name, addr, unitid, pdu)

Called by the Modbus Server I/O Server on every Modbus request received from a Modbus client.

The returned byte array is used as the Modbus response PDU (function code and data).

Parameters:

name: string - the name of the Modbus Server I/O server
addr: string - IP address of the Modbus client
unitid: numeric - the unit id set in the received Modbus request
pdu: string - the request PDU data, in hexadecimal string format.

Returns:

string - the response PDU data, in hexadecimal string format.

The JavaScript ModbusEvent function is called only when the Java ModbusEvent callback is not defined or returned a null value.

Network Services

httpCallEvent

httpCallEvent(address, secure, query)

Called when the HSYCO HTTP server receives a GET request with the following path:

/x/httpcall?query

The HTTP client's IP address must be in the trusted network range, or the httpcall request will be rejected.

This function shoud return a string, that will be sent as the text/plain answer to the HTTP client (with HTTP response code 200).

HSYCO will return a 404 Not Found response code if all of the following conditions are true:

no HTTP event matches the query in events.txt
the httpCallEvent JavaScript callback is not defined in events.txt, or doesn't return a value
the httpCallEvent Java callback is not defined in user.java or in any plugins, or returns null.

If the httpCallEvent is defined both in JavaScript and Java, the Java version return value (unless null) will be used in the HTTP response.

Parameters:

address: string - the IP address of the HTTP client
secure: boolean - true if the request is sent to the HTTPS server, false if the request is sent to the HTTP server
query: string - the string following the ? in the URL path.

Returns:

string - the string to send as the text/plain answer to the HTTP client.

LocationEvent

LocationEvent(mac, ip, zoneId)

Called, if the location service is active, when a variation in the association of a client to the Wi-Fi Access Points is detected.

Parameters:

mac: string - the MAC address of the client
ip: string - the IP address of the client, if available, or null (the IP address could be null if the associated device is not connected to the HSYCO Web interface)
zoneId: numeric - in case of association, it is the Access Point sequence number, according to the order defined in the LocationBases parameter in hsyco.ini; -1 if the client was de-associated from the Wi-Fi network.

SysLogEvent

 SysLogEvent(address, log)

Called when the HSYCO SYSLOG server receives a log message from a network client.

Note that this is a blocking call. The SYSLOG server will not process further messages until the last call has been processed.

Parameters:

address: string - the IP address of the SYSLOG client
log: string - SYSLOG log message.

PBX

PBXCallEvent

PBXCallEvent(host, caller, called)

Called when a call notification is sent to HSYCO by the PBX system.

If the method returns true, the request is recorded on the log file with the [OK] status, with [ERROR] otherwise.

The PBX should generate HTTP requests to the HSYCO Web Server, using the following formats:

http://192.168.0.50/x/vcall/<from>/<to>

or:

http://192.168.0.50/x/vcall?from=<from>&to=<to>

For example, the HTTP request:

http://192.168.0.50/x/vcall?from=21&to=25

is interpreted as a call notification from internal number 21 to number 25.

The HTTP client's IP address must be in the trusted network range, or the httpcall request will be rejected.

Parameters:

host: string - the IP address of the PBX server
caller: string - the caller number
called: string - the called number.

Returns:

boolean - return true to generate a log entry with [OK] status, false for [ERROR] status.

Squeezebox

SlimPowerEvent

SlimPowerEvent(index, power)

Called when a Squeezebox player is turned on or off.

Parameters:

index: numeric - player number, starting from 0 for the first player, based on the listing order of the slimPlayers parameter in hsyco.ini
power: numeric - 0: OFF, 1: ON.

SlimStatusEvent

SlimStatusEvent()

Called when a Squeezebox player changes its playback mode.

Parameters:

index: numeric - player number, starting from 0 for the first player, based on the listing order of the slimPlayers parameter in hsyco.ini
status: numeric - 0: OFF, 1: ON, 2: PAUSE, 3: PLAY, -1: UNKNOWN.

SlimVolumeEvent

SlimVolumeEvent(index, volume)

Called when a Squeezebox player changes its volume level.

Parameters:

index: numeric - player number, starting from 0 for the first player, based on the listing order of the slimPlayers parameter in hsyco.ini
volume: numeric - an integer number representing the volume change (not the absolute audio level) in a scale from 0 to 100; positive numbers correspond to a volume increase, negative numbers to a decrease.

Timers and Schedulers

UserTimerEvent

UserTimerEvent(name, active)

Called when a user timer or scheduler’s rule should be activated, and before executing the associated action in EVENTS.

It is also executed at the timer or scheduler’s rule deactivation.

This method must return a true value in order to make the timer or rule actually active and the associated actions executed.

Whenever the method returns false, the timer will not be activated, and the method will be called again once a minute for the scheduled duration of the timer.

In the same way, if the method returns false when the timer or rule is deactivated, the timer or rule will not be deactivated, extending the timer activation beyond the scheduled duration.

This is a blocking method.

Parameters:

name: string - timer name or scheduler’s rule name
active: boolean - true when activating and false when deactivating the timer or scheduler’s rule.

Returns:

boolean - true to confirm the timer event, false to block the event.

The JavaScript UserTimerEvent function is alway called, but its return value is used only when the Java UserTimerEvent callback is not defined or returned true.

User Interface

pageEvent

pageEvent(address, session, userid, project, page)

Called when a Web client initially loads a project and when navigating between pages.

There is no guarantee that the event would be fired the exact moment the page is loaded.

Network delays or errors could cause delayed triggering of this event.

Parameters:

address: string - the client’s IP address
session: string - session id string that uniquely identifies the client session
userid: string - the user id
project: string - project’s id
page: string - the page id, with the #landscape or #portrait suffix if the page has distinct orientation versions in the project.

uiClearEvent

uiClearEvent(session)

Called, following an explicit call of uiClear() or after the client session inactivity timeout expires, if the client session becomes active again (i.e. the client starts handshaking again with the server with the same session id).

Parameters:

session: string - session id string that uniquely identifies the client session.

userCommand

userCommand(session, userid, name, param)

Called by user clicks on buttons created in the Web interface with the user objects, by a USER action in EVENTS, or by the user() Java method and JavaScript function.

This function can optionally return a string. Any returned string causes the log of an [OK] status. If you want to prevent logging, for example to avoid sensitive information to be written in the log file, you should return the string “!”.

If you want to force the Web interface to show a specific page after the button is pressed (it would be like pressing a link object, return a string starting with “page:” followed by the page name; in this case, userCommand() will be called again when that popup or page is closed, with "/close" appended to param.

Parameters:

session: string - a session id string that uniquely identifies the client session
userid: string - the user id
name: string - the name field of the user object
param: string - the param of the user object

Returns:

string - log or go to page, see text above. If this function doesn't return a value, an [ERROR] status is logged in the log file, while any other string causes the log of an [OK] status.

The JavaScript userCommand function is alway called, but its return value is used only when the Java userCommand callback is not defined or returned null or an empty string.

userSubmit

userSubmit(session, userid, name, fields)

This function is similar to userCommand(session, userid, name, param).

When userSubmit() is defined, it will be called when a submit button is pressed, while userCommand() will continue to be called on user buttons.

userSubmit() provides a more convenient access to the values of multiple input fields in a form.

This function can optionally return a string. Any returned string causes the log of an [OK] status. If you want to prevent logging, for example to avoid sensitive information to be written in the log file, you should return the string “!”.

If you want to force the Web interface to show a specific page after the button is pressed (it would be like pressing a link object), return a string starting with “page:” followed by the page name; in this case, userCommand() will be called when that popup or page is closed, with "/close" appended to param.

Parameters:

session: string - a session id string that uniquely identifies the client session
userid: string - the user id
name: string - the id of the (submit!id) object
fields: array - the array of all input fields in the container where the (submit) object is located.

Returns:

string - log or go to page, see text above. If this function doesn't return a value, an [ERROR] status is logged in the log file, while any other string causes the log of an [OK] status.

The JavaScript userSubmit function is alway called, but its return value is used only when the Java userCommand or userSubmit callback are not defined or returned null or an empty string.

Examples:

The following code shows how to retrieve all field names and values of a submitted form.

function userSubmit(session, user, name, values) : {
	if (session.length > 0) {
		messageLog(user + ', ' + name + '=' + values);
		var keys = values.keySet().toArray();
		for (var i = 0; i < keys.length; i++) {
			messageLog(user + ', ' + keys[i] +  ' = ' + values.get(keys[i]));
		}
		return "";
	}
}

Create a project with a form and a few input fields in a container. Pressing the submit button should return something like this in the log file:

2014.01.31 13:54:32.034 - staff, submit1={keypad1=344, date1=20140131, input1=this is a text field} 
2014.01.31 13:54:32.038 - staff, keypad1 = 344 
2014.01.31 13:54:32.039 - staff, date1 = 20140131 
2014.01.31 13:54:32.042 - staff, input1 = this is a text field 
2014.01.31 13:54:32.043 - WEB USER COMMAND [submit1]: input1@this is a text field@date1@20140131@keypad1@344 [OK]

WebRootRequestEvent

WebRootRequestEvent(addr, secure, useragent)

This method is called when the Web server receives a root URL request. It can return a string to redirect the browser to a valid URL, or null to prevent redirection.

Parameters:

addr: string - the HTTP client’s address
secure: boolean - true if this is an HTTPS request
useragent: string - the Web browser’s user agent information.

Returns:

string - optional return string containing a valid absolute or relative URL

Examples:

The following code redirects any root HTTP request received by the HSYCO server to the manager page.

function WebRootRequestEvent(addr, secure, useragent) : {
	return "hsycoserver/manager";
}
