Dynamically changing the Configuration property of a Thing

[AjaySrini]

Can someone advise me if there is a way to change the configuration property of a thing dynamically (through a service).

My requirement is as follows :

I have a thing (Thing_1) that inherits TimerThing Template and in the Configuration tab, there is an 'Update Rate' set as 60000ms by default. Now, I need to change this configuration property dynamically from a service of another thing (Thing_2) based on the input provided to that service.

Is there any in-built service that I can use to update the configuration property dynamically ?

Here you have a code sample on how to do it:

// -- Parameters
var timerName = "yourTimerThingName";
var updateRate = 60000; // or anyother

// -- Constants
var CONFIGURATION_TABLE_NAME = "Settings";

// -- Start
var timer = Things[timerName];
if (timer!=null) {
    var actualValues = timer.GetConfigurationTable({ tableName: CONFIGURATION_TABLE_NAME });
    if (actualValues.rows.length>0) {
        actualValues.rows[0].updateRate = updateRate;
        var params = {
            configurationTable: actualValues ,
            persistent: true,
            tableName: CONFIGURATION_TABLE_NAME
        };

        // no return
        timer.SetConfigurationTable(params);
    }
    // -- A Full Restart it's needed, just doing a Disable/Enable doesn't works
    timer.RestartThing();
