I have a wireless thermometer and it seems to effortlessly communicate with the various sensors I have placed around the house. I would like to be able to have my PC track those readings. It seems like a simple thing to do since thee data is flying around. The problem is how do I capture the transmissions as the fly by? I assume they are using the 433 MHz frequency. While I am somewhat proficient at PC software development, I have never done any hardware work. I wouldn't know where to begin in capturing this data.
I know there are units for sale from various manufacturers but they usually have propriety software for interacting with it. I want to be able to write my own software. "That's my field of expertise, so naturally that's where I want to play."
It seems to me if I can simply poll the device on some schedule, I can easily record the value I retrieve. The question is, "How do I poll the device?" and "How will it answer?"
I have googled this but found very little. Most of what I have found seems to be industrial and scientific. I am more of a hobbyist looking to scratch an itch.
