Tried moving emitter around while sending commands and it worked in some places and sometimes in the same places didn't work so without knowing the precise location I'm unable to say if the codes are all ok or not. I like the idea of opening the box and seeing for yourself where the sensor is. Wish I would've thought about that when I was at the site instead of wasting hours online searching for product manuals that don't exist and/or don't have the info you're looking for.
