I was wondering why my controllers had different water percentage. From 53%-98%. I have only moved 3 to eto. 3 different hw versions. 2.2, 2.3 and a 3.0 unit. Anyhow I followed the workaround. Now I am showing 75%, 76%, 76%. The 75% is from a 3.0 unit. It is across the street from the other 2. It must be a little wetter 200 feet away..
