That is a valuable piece of information!
I actually tried maxim polinomial before for crc8. It didn't match. Although, maybe I missed something.
Anyway, This will help me very much. I thougth the wind was represented as meters per second
Thanks.Welcome to the Cumulus Support forum.

Re: Rain calculator for WS-2080
Hi Alan, It seems like i missed the last byte (checksum) of the frame. But I think it impossible to find out the checksum algorithm. i've been trying to guess it, but no one matched; Here are the frames i am getting: a5 01 91 4a 00 00 00 60 0e b8 a5 01 92 4a 00 00 00 60 0d e1 a5 01 92 4a 00 00 00 60...

Re: Rain calculator for WS-2080
Yes it is all working now! For my station the value which i should substract from the actual measurment is 0x190. So for temperature 26.1 (0x1295) if i don't use the high nibble it will be (0x295 - 0x190) = 0x105 (261) * 0.1 = 26.1 C. Nice... Do you know which model of a barometer sensor they are us...

Re: Rain calculator for WS-2080
Oh that is nice. will try it out. Did you know how they represent the temperature. it has 2-byte value but the high byte changes unpredictably. Anyway the temperature isn't necessary, still curious anyway. Well... if someone needs a source code of the reciever for atmel microcontroller for this spec...

Rain calculator for WS-2080
Hi. This questions might be asked... but i will try I need to find a formula to convert raw rain counter value to a precipitation rate (per hour or so). My station is WS-2080. The console is completly dead. I managed to crack the protocol. The only problem is to calculate the rain value. Did anybody...
