Frost risk

Hi all!

When I was working on automating my car heating/cooling I wanted to have a sensor that could detect the risk that there was frost on the windows to conditionally trigger defrost. I came across a very old repo that I couldn’t get to work. So I decided to build my own, first, HACS integration based on that repo.

Maybe some of you want to use it, so I thought to just share it here!

Nice work! This will help automating the preheating of our car.

Hi @Patrick1610!

I just installed the integration and I’m now looking at the device info. I understand that (almost all of) the rest of the world is working on a reasonable temperature scale, but - unfortunately - the country I’m is not :frowning:

Is there a way to convert this to Fahrenheit so that it calculates properly?

Looks like the Frost Risk Level will not tell me anything when we get closer or even below to the freezing point of 32F.

Current Temperature 68F:

Simulated Below-Freezing Temperature - 28F:
