Trying to make a puck js doorbell and need advice on range

I assume we have to clear the existing timeout or it only runs the once?

It should be fine because we do:

if (slowTimeout) clearTimeout(slowTimeout);
  slowTimeout = setTimeout(function() { 
  ...

The code I have at the moment is very similar

Yes, that's good for testing - but you're still not seeing good enough range from it? :(
