A few questions ...

Inside the battery compartment there's a 2D code to (IIRC) radbot.com/r/<serial no>. I imagine that originally did something, but now it just redirects to Vestemi's homepage. Was it supposed to do something unit specific, or just an oversight ?


Now, I assume the hardware comes apart if I remove the two screws visible from the mounting end ? I haven't tried it yet as I can't find a screwdriver that will fit ! I have screwdrivers that would fit if the securing ring wasn't fitted - but with the ring in place, it partially blocks access down the holes.

I assume that if I have a need for one where it will be shaded from room light, it wouldn't be much of a problem to remove the sensor from the board and relocate it to a remote (transparent) box ?
