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?

One of my whisperers gives a zero reading on all metrics about twice every 24hours. Other times it seems normal. Is it broken?

I have one Whisperer up and running just fine. Based on this I purchased a second. The second produced readings that were inconsistent when the device was placed next to the first Whisperer (read about half on moisture when compared to the first). So, I sent it back to Amazon for a replacement. The replacement arrived and it also appears problematic. The light reading is normal, but the temperature is 486 degrees F and the moisture is 1 percent. The device is stuck at these aberrant readings and they are obviously problematic. I've tried deleting the device and reinstalling several times. The result is the same.

Any advice or assistance would be appreciated.
