Event.HttpTrigger
The block defines the event generated by receiving of an HTTP command HttpTrigger
from the intercom HTTP server. When the HTTP command http://ip_addr/enu/trigger/i
is received, the event will be generated whose ID matches the value that follows d
'trigger/' in the HTTP command. The intercom sends a simple reply to this request (200
OK).
Parameters
Name – define a unique HTTP command identifier including alphabetical
characters and digits.
Variables
The HttpTrigger event is always generated by the HTTP command which can carry a list
of user parameters as included in the URI command.
http://ip_address/trigger/id?param1=value1¶m2=value2
The list of parameters follows the ? character. Each parameter must include the name
and value separated with the = character. If the list includes more parameters than
one, & is used as the separator.
The HTTP-received parameters are available as HttpTrigger block variables. The
variable name equals to the name of the parameter transferred.
Example
Event generated by receiving of the following HTTP command: http://ip_addr/enu/trigg
: er/opendoor
Event.HttpTrigger: Name=opendoor
Event.MulticastTrigger
The MulticastTrigger block defines the event generated by receiving of a command sent
via SendMulticastRequest. The request is a message sent by UDP to a multicast
address (235.255.255.250:4433) and can thus be received by multiple devices at the
same time. The message includes the command ID (Command parameter) and
additional optional parameters. The message can be password-secured (Password
parameter).
