That’s the Vero IR extension. It’s not connected at the moment, because the Vero is currently in line of sight.
I’ve tested both internal IR receiver and the extender. When I tested the extender, I placed the Vero inside the TV cabinet with door closed and internal IR sensor masked with electrical tape. Issue is still present, but when I place the Vero on top op the packaging box, there’s an improvement. That’s very weird, because the IR light should not reach the internal sensor. I’ve double checked that the IR light cannot reach the internal sensor, by unplugging the IR extender.
