Temperatures from compressor module

[bwindsor]

Firstly, thanks so much for this project, I've been using data from it for the last year and it's been brilliant. I have the Altherma 3 EDLA09DA3V3. I notice in the user manual it mentions 5 thermistors in the compressor module.

I can see the 4 "hydro module" thermistors fine. I can also see outdoor air temperature and "refrigerant_2" which looks like it may be R4T of the compressor module, but could be R3T or R5T. My question is do you know if these remaining temperature sensor measurements are sent over P1P2 and therefore may be accessible in some way?

I am running older firmware but from a brief look through the code I can't see a mention of any other refrigerant temperatures, and references like "R1T" seem to refer to the hydro module not the compressor module. Thanks!
