I’m intrigued and very much want to know the answer. If you figure it out or have updates on the investigation, I’d appreciate it if you ping me :)

I have no answers, but here are a bunch of questions:

I wonder if it could be caused by the difference in ambient temperature on each side of the door. Is the stairwell on that floor noticeably cooler than the lobby? Is there less of a temperature differential on the door upstairs where the handle feels normal?

What is the hvac like in the stairwell (if there is any)? Could it be causing this?

Are the mysterious handle and door identical to the handle and door on the floor above?

Haha. My brain went the same direction you did - After reading the post text, I thought OP might be looking to use the device as a standalone media player, not just client. I hadn’t noticed that OP specified “Client” in the title.
