ITC-308 going wild

My ITC-308 wifi has been working well for a month, but today it started reading really high “current Temp” values that are around 15-20° too high. I confirmed this with an independent thermometer. Is there a way to reset it to factory settings?

I also sat and watched the readings for a minute or two, and they jump all over the place. Is my probe broken?

Hello,
Please dry the probe with a hairdryer and then test the room temperature. Is the reading accurate?
If it still has a deviation of 15-20 degrees, please provide the probe placement environment, problem photos, and order information to email support@inkbird.com for after-sales service.
