I recently bought a whisperer and for the first few days it worked perfectly but now it consistently reports the temperature as being over 300 degrees celcius, and soil moisture at 0% even while it has been raining here for a week.

I've tried relocating the whisperer and deleting and re-setting it up twice but get the same result.

I'm unsure what else to try. Does anyone have advice or a fix for issues like this?

Thanks.
