@khufkens I spoke to the RICOH product manager for the THETA and although he doesn’t have an answer right now, he’s seen this on feature working in a demo. I now remember that I have actually seen this feature work as well. It was using some special equipment attached to the USB port of the camera. He’s going to ask his colleague in Tokyo if this can be enabled by developers like yourself that need to turn the camera on remotely.
No immediate solution right now, but there’s a possibility that we may be able to access a special command over the USB cable at some point in the future. The camera may support it right now without any modification. If I find the solution, I will send you the info.
