Is there a wireless thermometer that I can place outside and get readings on my computer?
I have a crawl space and I want to place a thermometer where it will use my wireless internet to take readings and I can retrieve them from my computer. I've been looking online and found nothing based on a combination of different research.
Will need additional support to research.
I have a wireless thermometer and it seems to effortlessly communicate with various sensors placed around my home. I would be able to have my PC title of these lectures. This seems a simple thing to do, since data is flying around you. The problem is how do I enter transmissions like the fly by? I guess they use the 433 MHz frequency. Although I am somewhat skilled in software development for PC, I've never done any work equipment. I do not know where to start capturing the data.
I know there are homes for sale from various manufacturers, but they usually have proprietary software to interact with it. I want to be able to write my own software. "This is my area of expertise, so naturally that's where I want to play."
It seems to me that if I can simply query the device on certain times, I can easily record the value I get. The question is: "How can I query the device?" And "How do we respond?"
I googled it but found very little. Most of what I found seems to be industrial and scientific.I'm pretty amateur looking to scratch an itch.

The problem is that you have to know a lot about the hardware and firmware to do this. And he owns. And even if they are willing to share, it is sometimes difficult to find people who really know nothing. It is unlikely that they use a standard protocol, for there is none. There was a time you may get a configuration Heathkit or others where the idea is that you learned something, but I have not seen these things lately.You can make your own without too much effort, but the cost would be much more than the units Walmart. Most consumer goods these days are really disposable black boxes. The people who designed it may not even kept records as they no doubt it was the contract of a sudden a. That is globalization. For a time it was a requirement that foreign electronic devices came with a diagram at least, but they have even given up on that.
However, you might have a chance if you can find chips on a unit and finding the detected data streams and divert them to a serial interface. But even that is not trivial, but often feasible.It is also possible to buy or make an FM receiver (mostly FM) on this frequency and recording gusts for analysis. It's all about how you want to do. It can be done if you want badly enough, I did worse. If you know enough about electronics and computers, it is difficult enough to keep you away. It is fairly easy to ensure it is not useful
Some diodes can work as excellent devices provide temperature readings high accuracy instantly.
