Is there a sensor that can detect frost?
I want HA to notify me if my car needs scraped in the morning. Currently I check if the temperature drops to below 42F overnight. I get about a 50% success rate.
I think you’d have to factor in dew point and wind speed. Even so I don’t think you’d approach 100%.
That’s why I’d love a sensor that can tell me if it’s covered in frost.
Did You find such a sensor?
Nope, nothing found. Thought about making my own.
