I think these are all 07E2, mode 21. I think for the temps MG1 is always first and there is an offset of 50 Centigrade. I think C2 and C4 are 4 bytes each, CD and CE are 1 byte for each temp, giving a range of -50 to 205C. That would mean you could only display one at a time unless you had 2 SG's. Unfortunately, I have no way of testing any of these. But this is more or less how I sluethed the FEH PIDs a year ago.
