19.1.7 Retrieving ISY Variables into a Tasker variable
This is how to get the content of an ISY variable with Tasker - and store the results in
Tasker Global Variables.
First, setup the 19.1.2 Network Awareness section. This is so you get nice, fast API access
on the same LAN as your ISY - but secure remote access (either directly, or via the ISY
Portal) while away from home.
19.1.8 Master Variable Retrieval Task
First - a master task that will be called by others... I called mine 'ISY-GetStatus-Var'.
•
'Anchor' - 'start_request'
•
'HTTP Get' - Server:Port='%IsyUrl' -
Path='%URLPrefix/rest/vars/get/%par1/%par2' - Continue Task After
Error='Checked' (If direct and self signed cert, check 'Trust Any Certificate')
•
'Wait' - 'Seconds'=2 - If %HTTPR eq -1
•
'Goto' - Type='Action Label' - Label='start_request' - If %HTTPR eq -1
•
'JavaScriptlet' - Paste the 'Code' from the next box...
•
'Return' - Value='%varLastVal' - Stop=Checked
The content of the JavaScriptlet is:
•
var parser = new DOMParser();
•
var xmlDoc = parser.parseFromString(global('HTTPD'),"text/xml");
•
var varHeader = xmlDoc.getElementsByTagName("var")[0];
•
setGlobal("varLastType",varHeader.getAttribute("type"));
•
setGlobal("varLastID",varHeader.getAttribute("id"));
•
setGlobal("varLastSet",xmlDoc.getElementsByTagName("ts")[0].childNodes[0].node
Value);
•
setGlobal("varLastVal",xmlDoc.getElementsByTagName("val")[0].childNodes[0].nod
eValue);
•
setGlobal("varLastInit",xmlDoc.getElementsByTagName("init")[0].childNodes[0].no
deValue);
19.1.9 Retrieve value using master variable retrieval task
I have a variable I wish to retrieve... 'FR-Temp'. It is a 'State' variable with ID 124.
This is the task you create to get this variable:
•
'Perform Task' Name='ISY-GetStatus-Var' - Parameter 1='2' - Parameter 2='124' -
Return Value Variable='%var_val'
