Flow rate Rotex HPSU 508 #380

Open Micha031982 opened 8 months ago

Hi everyone,

I searched for the flow rate parameter for my heat pump Rotex HPSU 508 Many discussions but no real result

I found 2 other projects And they seams to be able to read this value

  1. Pyhpsu https://github.com/Spanni26/pyHPSU/blob/master/HPSU/canemu.py

It seams they use the register 32 But I have no clue how to translate the Adresse to the format used in this project {"name":"flow_rate","resp":"32 10 FA 01 DA 05 70"},

  1. IoBroker.canbus

https://github.com/crycode-de/ioBroker.canbus/blob/master/well-known-messages/configs/rotex-hpsu.md

Here i did not find the Bus Adressen

Can someone explain me how to translate the bus address from 1. to the format in this project ?

thanks in advance Michael

You can't translate, they are different protocols that are managed by different interfaces and have access to different information sets/registers.
