(Also, I would note that the question was answered in the thread that you linked to. the answer at the time that that question was posed, which was over a year ago, was that at that time smartthings didn’t do over the air updates even for its own devices. They do now, but again, only for a limited set of partners.)
Thank you for the reply.
We are releasing products now, none of our products require firmware update today.
But as one of the developer I wish to gather information for this feature.
We will follow the partner path.
