I've had one of those car covers for a while now that you can put over the car to prevent ice from forming on the windows in cold temperatures. This cover is a very easy way to save yourself having to scrape your car windows in the morning.<\/p>\n\n\n\n

The only disadvantage with these covers is that you have to pull the cover over the car first. <\/p>\n\n\n\n

Unfortunately, I discovered that I have a special talent for attaching the cover to the car whenever I don't need it (too warm) and forgetting to attach it to the car just when I need it (cold enough).<\/p>\n\n\n\n

That's why I made this little NodeRed Flow that always informs me about cold temperatures - regardless of whether I've forgotten it or not. <\/p>\n\n\n\n

This means that if the average temperature at 8 p.m. in the evening or at 6 a.m. in the morning is below four degrees, I will receive a message via Pushbullet in the evening. This means I still have enough time to put the cover on in the evening or (if I forgot to do it the night before) I can plan a little extra time for scraping the windows clean.<\/p>\n\n\n\n

Of course, this flow can also be used in combination with Pushover or a simple email notification. <\/p>\n\n\n\n

I have described everything you need to integrate this flow into your NodeRed instance in the following article.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

<\/strong>So that you can install new nodes, NodeRed should of course already be installed.
