Is there a way to reset all settings back to default?

I have a whisper installed and was wondering if the setting "Moisture to Skip Watering" is based on topsoil or subsoil moisture.

I recently ordered a second whisper and installed it the same way as the first one I received (which is still working fine)  It connects just fine and I can even change the color of the LED for a while.  But it reported only once to the app and that was it.  I have tried reconnecting it to WiFi, I even deleted it in the app and reinstalled it with no success.  After the initial connection it seems to just stop working.

I just received my new Whisperer and when I push the power button, I get one single red LED flash and that's it.  It won't do anything else.  I put it in the sun for a couple of hours to see if the battery was dead, this didn't solve the issue.

For some reason, when I give Google the command to "talk to netro sprite to water zone for 5 minutes" or "ask netro sprite to water zone for 5 minutes" Netro comes back and says "I have stopped watering.  What else can I do for you?"  It won't do anything else but turn off the zones.  Why is this?
