Event Keywords

An event is defined as a keyword that identifies the event type, usually followed by one or more parameters and conditional operators. Every keyword uses a specific syntax that interprets parameters according to its own rules.

System Events

DAY

A stable condition that is true during day time, as computed based on the latitude and longitude data set in hsyco.ini and the SunriseOffsetMinutes and SunsetOffsetMinutes parameters.

Event	State	Description
DAY	stable	triggered at sunrise; remains true until sunset

Examples:

DAY : IO k.33 k.34 k.35 = 0

HAACTIVE

This event is triggered when HSYCO is a master or slave in a high availability configuration and the server is active.

Event	State	Description
HAACTIVE	transient	this HSYCO server is active

Examples:

Send an email when the slave HSYCO server becomes active:

HAACTIVE AND $HAMASTER$ = 0 : MAIL email@hsyco.com = hsyco@hsyco.com "Sent from HSYCO" "The slave server is now active"

HSYCOSTART

This event is triggered only once when HSYCO starts, after the initialization and HTTP server start-up, but before the execution of the different field devices interface threads.

Event	State	Description
HSYCOSTART	transient	occurs only once at start-up

Examples:

HSYCOSTART : $count = 0

INIT

This event is triggered when HSYCO reloads any EVENTS file.

Note that, because HSYCO takes a few seconds to reload these files after they are changed, if multiple changes occur very closely in time, a single INIT event may be triggered for a batch of changes.

Reloading occurs when HSYCO starts and every time the file is manually saved, even with no content changes.

Event	State	Description
INIT	transient	an EVENTS file has been reloaded

Examples:

INIT : $count = 0

NIGHT

A stable condition that is true during night time, as computed based on the latitude and longitude data set in hsyco.ini and the SunriseOffsetMinutes and SunsetOffsetMinutes parameters.

Event	State	Description
NIGHT	stable	triggered at sunset; remains true until sunrise

Examples:

NIGHT: IO k.33 k.34 k.35 = 1

POWER

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

Event	State	Description
POWER	transient	triggered by any change to the power level
POWER > power POWER < power POWER >= power POWER <= power	stable	occurs when a change in the power level is detected. It is true if the comparison condition is satisfied

Parameters:

power - the power in Watt.

Examples:

POWER > 2000 : IO k.70 = 0
POWER : LOG "NEW POWER: " $POWER$

PROGRAMTIMER

Triggered by a program timer.

Event	State	Description
PROGRAMTIMER name	transient	triggered after the program timer’s set time-interval

Parameters:

name - program timer id.

Examples:

Turns on light k.33 approximately 10 seconds after the click on a user button:

USER timer : PROGRAMTIMER test = SET 10
PROGRAMTIMER test : IO k.33 = 1

SUNAZIMUTH

This event is triggered every time there is a change in the integer part of Sun’s azimuth angle (the angle between North and the Sun’s projection on the horizon), as computed based on the latitude and longitude data set in hsyco.ini and the SunriseOffsetMinutes and SunsetOffsetMinutes parameters.

Event	State	Description
SUNAZIMUTH	transient	triggered when the Sun's azimuth changes
SUNAZIMUTH = value SUNAZIMUTH > value SUNAZIMUTH < value SUNAZIMUTH >= value SUNAZIMUTH <= value	stable	true if the condition matches. Angles are compared ignoring decimals

Parameters:

value - angle in decimal degrees, as a positive integer number, between 0 and 359.

Examples:

SUNAZIMUTH > 180 AND SUNAZIMUTH < 220 : IO k.54 = 0

SUNELEVATION

This event is triggered every time there is a change in the integer part of Sun’s elevation angle (the angle between the horizon and the Sun), as computed based on the latitude and longitude data set in hsyco.ini and the SunriseOffsetMinutes and SunsetOffsetMinutes parameters.

Event	State	Description
SUNELEVATION	transient	triggered when the Sun's elevation changes
SUNELEVATION = value SUNELEVATION > value SUNELEVATION < value SUNELEVATION >= value SUNELEVATION <= value	stable	true if the condition matches. Angles are compared ignoring decimals

Parameters:

value - angle in decimal degrees, as an integer number, between -90 and 90.

Examples:

SUNELEVATION > 45 : IO k.55 = 0

TIME

The current time event.

In its simple form, it is just a transient event that is triggered every minute.

It can also be used as a stable condition, comparing the current time with a constant time in the HHMM format.

Event	State	Description
TIME	transient	triggered at the beginning of each minute
TIME = hhmm TIME > hhmm TIME < hhmm TIME >= hhmm TIME <= hhmm	stable	compares the current time with the specified time in the HHMM format

Examples:

TIME : CAMERAREC entrance = 60
TIME = 0930 : IO k.33 = 0

Cameras

CAMERA

This event is true while HSYCO is recording video from a specific camera.

Recording could start automatically when a camera notifies a recording request with the recording HTTP API call:

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

Recording can also be triggered by the CameraRecTrigger() Java call or the CAMERAREC or CAMERARECFULL actions in EVENTS.

Event	State	Description
CAMERA name	stable	the camera is recording
CAMERA name = zone	transient	transient event triggered by a camera recording request with zone information

Parameters:

name - the camera id
zone - the zone id.

Examples:

The event will reset to off when no Web client has been loading images from the camera for several consecutive seconds.

Event	State	Description
CAMERAVIEW name = status	stable	the camera real-time view status

Parameters:

name - the camera id
status - set to “on” or “1” to match the event when HSYCO is displaying the live view, and to “off” or “0” to match the event when HSYCO is not displaying a live view of the camera on any client.

Examples:

CAMERAVIEW entrance = on

DMX

Events on the DMX bus channels.

Event	State	Description
DMX address	transient	any change to the channel value
DMX address = ON	stable	channel value > 0
DMX address = OFF	stable	channel value = 0
DMX address = value DMX address > value DMX address < value DMX address >= value DMX address <= value	stable	the channel value is equal, greater, greater or equal, less, less or equal to the given value. Valid values are numbers between 0 and 255

Parameters:

address - when using one DMX gateway, address will be a standard DMX-512 address between 1 and 512. If there is more than one gateway, 1000 must be added to the DMX address for the second gateway, 2000 for the third one and so on. For example, 2100 stands for the address 100 on the DMX bus controlled by the third gateway.

Examples:

DMX 100 = ON
DMX 1200 = OFF
DMX 135 = OFF OR DMX 100 > 50
DMX 41 <= $LEVEL

DMXSTART

This event is triggered 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.

Event	State	Description
DMXSTART busid	transient	occurs when HSYCO connects to the DMX gateway. HSYCO establishes the connection at start-up. If the gateway is turned off and then on, or if communication errors occur, HSYCO automatically re-establishes the connection as soon as possible, calling this event in case of success

Parameters:

busid - the id of the DMX gateway. The first gateway has address 0. The second has address 1, etc. busid can be omitted if 0.

Examples:

DMXSTART: DMX 100-200 = OFF
DMXSTART 1: DMX 1100-1200 = OFF

IR

This event is triggered when an IRTrans receives and successfully decodes an infrared command.

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

Event	State	Description
IR name = command	transient	command received by an IRTrans device

Parameters:

name - the IRTrans, as defined in the IRTrans parameter in hsyco.ini

IO name = value IO name > value IO name < value IO name >= value IO name <= value	stable	the value is equal, greater, greater or equal, less, less or equal to the given value. The names and values of the I/O variables are specifically related to the type of I/O server. Values can be numeric or strings

Parameters:

name - the data point name of the input or output port. According to the type of server, the format changes but it generally appears as server name, as declared with the ioServers parameter in hsyco.ini, followed by a dot and the input/output port name. See the Application Notes for more information.

Examples:

IO tempmeter.indoor > 25.5
IO contacts.c1 = 1

IOSTART

This event indicates that the connection with an I/O server has been correctly established.

It should be safe to associate this event with actions that set the I/O server writable variables.

IOSTART id	transient	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

Parameters:

id - the I/O server number, starting from 0, based on the listing order of the ioServers parameter in hsyco.ini; If only one I/O server is available, it can be omitted.

Examples:

IOSTART: IO contacts.c1 = 1
IOSTART 2: IO relays.door = 1

Leak Detector

LEAK

This stable event is triggered by a LEAK action when the Intelligent Leak Detector detects a leak condition, or the leak condition is reset.

See the LEAK action for additional information.

Event	State	Description
LEAK name	transient	any status change of the leak detector
LEAK name = ON	stable	leak condition detected

LEAK water = ON : MAIL john@example.com = hsyco@example.com “Urgent Message from HSYCO” “Leak Detected”
LEAK water = OFF : MAIL john@example.com = hsyco@example.com “Message from HSYCO” “Leak Reset”

Network Services

HTTP

This transient event is triggered 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, unless HTTPServerLowSecurityEnabled is true and the request is sent using HTTPS

If a matching event is found, and the httpCallEvent JavaScript or Java callbacks are not defined, the HTTP server will respond with an "ack" 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
the httpCallEvent JavaScript callback is not defined in EVENTS, or doesn't return a value
the httpCallEvent Java callback is not defined in user.java or in any plugins, or returns null.

Event	State	Description
HTTP query	transient	the HSYCO HTTP/HTTPS server received an HTTP GET request: /x/httpcall?query

Parameters:

query - the string following the ? in the URL path.

Examples:

HTTP "test" : log = "test http call"

LOCATION

LOCATION aa:01:33:e4:41:00 = ON
LOCATION aa:01:33:e4:41:00 = OFF

PING

This transient event is generated by a PING action, that tests the reachability of one or more IP hosts, identified by their hostnames or IP addresses, within the optional timeout defined in milliseconds (or using a default timeout of 200 ms).

Event	State	Description
PING hostname = ON	transient	the device has been reached after a PING action
PING hostname = OFF	transient	the device is not reachable after a PING action

Parameters:

hostname - the IP device name or IP address, as called by the corresponding PING action.

PING 192.168.1.1 = OFF : LOG = "router is off-line"

URL

This transient event is generated by a URL action, that sends an HTTP or HTTPS request to a given url.

The response can be checked for a specific numeric status code or looking at a string in the response body.

Event	State	Description
URL “url” = status_code	transient	the response status code to the HTTP url request is equal to status_code
URL “url” *= “string”	transient	the response data to the HTTP url request contains the string

Parameters:

url - a full url, including the mandatory http:// or https:// query scheme and optional query string
status_code - the numeric status code returned by the server’s response; 200 is usually the code returned by a successful request
string - the event matches any response containing the given string in the response body.

Examples:

TIME 0800: URL GET "http://10.0.0.5/cgi-bin/cmd.sh?id=relay1"
URL "http://10.0.0.5/cgi-bin/cmd.sh?id=relay1" : LOG = "relay opened"

PBX

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

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.

Event	State	Description
PBX from = to	transient	phone call event, with originator and destination data

Parameters:

from - the caller number
to - the called number.
