Does anyone have any info on La Crosse TX141 protocol?

Update:

The protocol is as follows:
32 bit messages, repeated 6 times.

  1. 8 bits for id
  2. 4 flag bits. 1st bit is battery indicator.
  3. 12 bits for temperature. Temperature in float format xx.x * 10, truncated to int16.
  4. 8 bit checksum LFSR-based Toeplitz hash

This?

You can determine the bit timing and protocol of the transmitter using the methods in this tutorial: Reverse Engineer Wireless Temperature / Humidity / Rain Sensors — Part 1 « RAYSHOBBY.NET

But without the transmitter, it is probably hopeless. The TX141V2 sensor is available on eBay.
