Hello.
I'm sorry for my english.
The Institute are developing stand.
Measure performance in different weather conditions.
To obtain data using metio WMR88.
Write a program in Delphi.
Write a procedure to USB HID device, but can not decode and manipulate the data reception.
Prompt please decryption.
Program will be used only for the institute.

See this: http://www.dg1sfj.de/hardware/hw_wmr100_protokoll.html and the WMR100 spreadsheet in this thread: http://sandaysoft.com/forum/viewtopic.php?f=16&t=5912

Is Cumulus not suitable for your purposes?

The data do not fit the description WMR100
Prompt treatment
I have tried so:


07 FF 00 42 80 E1 00 20 - termometr indoor 22.5 C, 32% - Ok

04 FF 00 42 80 14 00 00 - termometr indoor 2,0 C, 0% - no correct

Please Help

The messages back from the station will be of variable length, it looks like your program is using a fixed sized window?

Have you tried just connecting up a terminal emulator and see what is really coming back from the station?

You haven't understood the protocol correctly. The first byte in each USB frame tells you how many bytes in that frame are valid. You then have to reassemble the data packets from the fragments in the USB frames. In the second line you quote, only the first 4 bytes are valid, so you have to look at the next frame(s) for the rest of your temperature packet.

A very big thank you.
For All Example:

01 FF 01 80 B9 01 C0 32
07 00 42 C1 16 00 5F 14
05 00 00 20 AC 01 5F 14
Is: FF 00 42 C1 16 00 5F 14 00 00 20 AC 01
FF - Start Data
00 42 -Termometer
C1 - 1 channel
16 00 - "+ 2,2C"
5F - 95% humidity
20 - End Data
01AC -CS = 20+00+00+14+5F+00+16+C1+42+00

You've got it. It also tells you:

temp trend = 0 = steady
dew point = +2°C
humidity trend = 0 = steady

Though you may not be interested in that!
