you should either try using a stock, unaltered Access, or, put yours back to exactly how it was from the factory and see if it works properly then; no one else seems to be reporting the issue you are, so that is the first thing I would try..
Too late. It was already returned but that would be an interesting experiment. I just don't see how an improved antenna for 5 in 1 would be detrimental to Atlas given they use the same sensor transmitter.
I'm happy with 5 in 1 and Access. It's been rock solid for months and rarely deviates from 4 bar signal strength at 125'+ range so I'll just stay the course.
None of the added Atlas features were that compelling to me with the exception of the console. I think they nailed it with the new TFT touch screen console.
My idea of a perfect weather station would be the Atlas touch screen console except with integrated WiFi (like Ambient Weather's 2902) and a Davis 1000' range Vantage sensor. Everyone has a piece of the puzzle but no-one has put it all together.
P.S. I see the Atlas + Console bundle has just dropped to $175 @ Amazon.
