Need help with some variables, please

[Guenseli]

Hello,
I managed to interface the A32NX with AAO fpr my VrInsight MCP Combo and my Elgato StreamDeck.

As example I can control EFIS Modes, RNG, Probe heat and all other deicing, APU Bleed and APU Start.

What I do currently not find are the variables for

APU Master
and the Batteries 1 + 2

Could you help me, please?
many thanks!
