So I spoke with another Tech from yuneec today and got a totally different answer. He said realsense is only on when we flip the obstacle avoidance switch. HE SAID, it's never automatically on, even in smart mode and RTH. Reason being it cuts the speed of the H and that may not be appropriate for all situations.
I've tried it in allsorts of situations. The realsense is only on when you have that switch fully down. Middle and top are off. If you turn it on during RTH, the thing will climb to the default 66ft or to whatever you set it to. If it comes across a tree 124ft tall, it will navigate around it etc... Even with the wizard in smart mode (default follow), the realsense is not on, you have to enable it. When it is enabled, the best way of telling that it is indeed on, is by observing the front nav lights (white) flashing rapidly - solid white indicates that it is not on.
All of this aside, it does cut the speed quite a lot (11mph max), but it works amazingly well - makes me laugh each time I use it. It also learns the environment, therefore, the more times you fly in the same place, the faster it will navigate it on subsequent occasions.
Hope this helps.
Chris.

I have had a RealSense Pro since the middle of July (also have a regular H). Slate, this tech is entirely correct.
Chris my friend, You are also correct, as usual. The flashing front white lights, and when the RealSense spots an obstruction, the "Pings" you hear (I love those pings).
The RS Pro will only fly the craft by itself in Watch Me and Follow Me modes. You always must switch it on first. The front Sonar AND the IPS bottom Sonar are always active on the RealSense Pro, can not be turned off. In Angle mode, as noted, it works if ON but the craft must face direction of travel.
With the RS Pro, if you hit RTH OR if the craft initiates RTH (craft lost control signal but GPS is OK), Immediately switch the RS OA switch ON.
The exception would be if no obstacles are in the way and/or the battery is low. Always remember that the OA icon on the ST16 screen is
green for RealSense active, and
yellow for not available.
Mickey, the video can indeed be jerky and of little or no use in commercial situations. I love the self-piloting ability but that's just me. To me it demonstrates the future. Future meeting today, where the drone is autonomous, piloting your mission from here to there and back all by itself. A ROBOT of the sky.
