I only got my system delivered yesterday, so this could be something that I doing wrong, I have one whisperer in the back garden and one in the front. I live in Merida Yucatan and so it's hot all the time. The whisperer in the back is in direct sunlight most of the day yet it's reporting the temperature as 24. The one in the front is shaded by the house yet that is reporting 33. Both seem to be reporting incorrect moisture levels in both the topsoil and subsoil. Yucatán drains through stone to underground water sources so I would expect both topsoil and subsoil to be showing very arid.
Can anyone advise?
