Angels, you would need to store/ log the property values. If you have access to the ThingWorx tutorials, please do check the Streams and Value Streams section. Or the Data Storage section at the ThingWorx Help Center.

    Hi Aanjan, thanks to  the ThingWorx Help Center, I would access the QueryPropertyHistory Services. But the POST method need two DateTime type parameter if I want to do the interval analysis, I try to use the string like "startDate=2016-02-23 06:10:10" but it returned Unable To Convert From java.lang.String to DATETIME. How can I send the DateTime type parameter? Thanks!
