It definitely does looks like it. I have changed the location of my kit and keep it in office all day so may be a lot warmer and less humid everywhere.

Moreover my readings did start getting higher with weather getting colder so may be there was a correlation. Let's see how it goes.Looks like your blip may be over.![]()
