Unreliable connection to external temp
You cant count on the temp gauge to stay connected. None of the "help" suggestions have any bearing on the problem. It gets worse the older the unit gets, despite fresh batteries measured as good. If you dont need a network connection to monitor remote temperature, youd be better off with a much cheaper unit from Amazon. It looks like the company put lots of resources to slick looking devices that dont work well.
