I have a front yard with zoysia grass, about a thousand square feet, no trees. My app keeps telling me that it will water this grass tomorrow. It is obvious that it needs watering, but the next morning I see that it has not been watered and it says I will water it tomorrow. There is no rain forecast, it has been very hot. It Waters the rest of my yard properly, it's just my front yard that it does it like this. Why does it keep changing its mind?

Also this same area, my front yard, has no trees but the app says there are trees on it. And I cannot change it. I would think if this area had trees on it it would be taking much more water and the app would water more. How can I change this on the app?

I have a Whisperer that the battery runs down on, even when placing it in good sunshine. I can place it under a lightbulb a couple inches away for a couple of days and it charges up. But after placing back in th yard it goes down again. This is after placing it right next to another Whisperer that charges just fine. Have tried deleting and reinstalling. Is there something else I should try?
