How can I Fetch specific property data from QueryPropertyHistory and show in a line chart graph.

Hello,

 

I want to fetch a specific property data from QueryPropertyHistory service.

consider like I have a thing and have a humidity and Temperature property. So I want to only fetch Temperature property data from QueryPropertyHistory. How can we do that?

 

Thanks.

Hi @Pratik_Aswale 

 

In Select Entity you can select your Thing Name

 

Select Service QueryNamedPropertyHistory service in service category

 

After that, pass your thing name to EntityName

Hi @Pratik_Aswale

 

Pass Thing Name from Drop down to service dynamically. It should work.
