I would like to build a custom SVG image in SmartThings based on SmartThings device state. I want a 3rd party service to be able to grab that image from a URL. How can I do this?
This feature is not currently available, but if you want to show this picture on a third party page, you could receive the status and change the picture accordingly.
I can suggest you to check the OAuth Integration documentation, this helps you to interact with the SmartThings API (get device status, send commands to devices, and others) from a third-party source; also, here are some samples.
Please, remember that it’s not allowed to use or change the SmartThings Logo for copyright reasons.
I hope it helps you.
