Hi,

First, thanks for your hard work !

I successfully connected AquaMQTT pcb v2 to my water heater but i have the famous "Unknow protocol" :-(

The HMI only has 3 cables (RBW) and looks like this :

I have setup AquaDebug and here a the dump :

aquadbg_debug_dec.csv
aquadbg_debug_hex.csv

Thanks !

Hey @ellmout, sorry for the long response. Indeed, this is a new kind of protocol. Unfortunately it seems it does not share any similarities with the previous protocols and the message pattern/structure is different.

I put some time into the traces and I believe there is a message pattern visible. I don't want to promise implementing or adding support for this, but do you have recordings from a signal analyzer? It would be the next logical step to isolate/identify messages, to see if at least this behavior is the same as we have for other heatpumps.
