However, my RFM69HCW picked it up and I was able to decode it as raw data which didn’t make too much sense. My spectrum analyzer shows a signal from a 915 MHz temperature sensor that is so infrequent as to defy analysis. I was encouraged when I took apart the C82929 and found an 8266 chip in the circuit board. I had also thought I could just grab the signal from my router as it tries to forward to the La Crosse View App. I didn’t see any responses to amigadragon post on Januat 2:11 pm about grabbing the signal with RFM69HCW.

#LA CROSSE WEATHER RADIO CLOCK CODE#
If you have a similar unit and are interested in extending its capabilities, has posted plenty of code on his site. So far, it looks like his temperature monitoring system is working quite well, though he has several improvements planned for the near future. It took a bit of work but he eventually got it, and can now record data packets knowing that the data has come over the air intact. The last hurdle he ran into was figuring out how the system’s CRC encoding worked. He dug further, and with the help of some data he found online, he was able to decode the data packets. He sniffed the signals using Audacity, and eventually found that the base station received 40-bit data bursts from each sensor.

Instead, he started sniffing the data coming across the wireless link, and while he didn’t quite yet know what he was seeing, it was a start. He thought about tapping into the bus that controls the LCD in hopes of finding an easy to decode signal, but the weather station used a proprietary chip with an integrated LCD controller, making it all but impossible. He tore into the base station and started looking around for easy places to get at the data he was looking for. He thought that the modular design of the system would make it great for use in his home automation project if he could only get his hands on the data. Got a La Crosse wireless weather station as a gift and thought the LCD display was great, but he was dismayed that there was no means of extracting the temperature data for use on a computer.
