How to retrieve name of a thing by specifying ID and accessing its properties

Good morning!

I have created  a few Things which inherit the properties from a ThingTemplate which holds a property Identifier string and another property for temperature.

In addition, I have created a helper thing to create a static service. This service gets two inputs: an identifier string and the temperature.

The service should retrieve the name of the thing which holds the same identifier string and should update the temperature property.

I have already found a function which seems to be made for that. It is called GetThingNameForIdentifier(identifier) and returns a THINGNAME.

But I haven't found anything on the internet on how to use this datatype and how to access the thing's properties.

Any suggestions?

Thank you in advance for your help

Theresa~

      hi Ankit Gupta​,

      and how do I use the GetThingnameByIdentifier(identifier) function?

      Is it like this or am I doing anything wrong:


      var params = {
      identifier: ID/* STRING: ID is the property Name of the Thing */
      };

      // result: THINGNAME
      var thingname = Resources["EntityServices"].GetThingNameForIdentifier(params);

      Things[thingname].temperature= temperature;

      thank you again for your help!

      because if I test my service I get a the following error:

      TypeError: Cannot set property "temperature" of null to "40"
