TX22 (wind,rain,temp,hum)...

[njordan77]

Hi, thanks for your effort and development done...

Is there a chance that you are also trying to support TX22....its already implemented in the LaCrosse-LaCrosseITPlusReader code (fhem).

Packets look like this....

Data - organized in nibbles - are structured as follows (example with blanks added for clarity):
a 5a 5 0 628 1 033 2 000 3 e00 4 000 bd

data always starts with "a"
from next 1.5 nibbles (here 5a) the 6 msb are identifier of transmitter,
bit 1 indicates acquisition/synchronizing phase
bit 0 will be 1 in case of error
next bit is the low battery flag
next three bits (here 5) is count of quartets transmitted
up to 5 quartets of data follow
each quartet starts with a type indicator (here 0,1,2,3,4)
0: temperature: 3 nibbles bcd coded tenth of °C plus 400 (here 628-400 = 22.8°C)
1: humidity: 3 nibbles bcd coded (here 33 %rH)
2: rain: 3 nibbles, counter of contact closures
3: wind: first nibble direction of wind vane (multiply by 22.5 to obtain degrees, here 0xe*22.5 = 315 degrees)
next two nibbles wind speed in m/s
4: gust: speed in m/s
next two bytes (here bd) are crc.
During acquisition/synchronizing phase (abt. 5 hours) all 5 quartets are sent, see example above. Thereafter
data strings contain only a few ( 1 up to 3) quartets, so data strings are not always of equal length.

Hello
yes. There is a chance. However I don't own this hardware. Without real data it's rather difficult to develop a proper support.
I can check if there is some JAVA based TX22 code out there already which I could reuse.

Hi, i at least know the message scheme + have already terminal RAW data coming in....
hope this would help a little...

What I receive is for example this:

OK. I see. Development with some sample values and without the actual hardware would be possible I think.
However I'm working on many other projects atm where I need to integrate equipment I own. So this TX22 has - unfortunately - very low priority for me.

Feel free to open a PR and contribute to this project.
