Michael,

Is the request ID 0x7e4, and do you have a trace of this? is it just a 1 byte response, with the following range:

0/2 - 40 = -40 celcius

255/2 - 40 = +87.5 celcius

The other source listed this as:

"*H2 Outside Temp Filtered", "OAT Filtered","22801F","((A-40)/2)",-20,50,"C", 7E4

Which is slightly different. For example byte value 100 gives:

(100/2) - 40 = +10 celcius

or (100-40)/2 = +30 celcius

?

Regards, Mark.
