Hello,
[Sorry for writing in English, I'm not a German speaker]
Thank you for this thread, found some helpful information - I was doing the same thing (decoding F1/F2) on my own, however I found an additional resource.
Go to opensource.samsung.com/uploadList?menuItem=home_appliances&classification1=airconditioners and download the WiFi Kit source code, WIFIKIT_R18_TZ4, WiFiKit_Source.zip. It's a Java project and you can find some code that is not part of S-NET Pro2.
I have an EHS Split, 4KW, AE040RXEDEG/EU with AE260RNWSEG/EU. I'm currently decoding everything that goes over F1/F2 using a Python script, pushing everything to Vertica DB, then visualize it in Grafana. Next step would be to also push over to MQTT in Home Assistant, but only a subset of the messages that I'm interested in.
Some of my goals include computing heating / cooling COP, DHW COP, (negative) impact of deicing. Some of that I've already achieved using the water flow info, in/out temperatures.
I would like to be able to "fakely" report the indoor temperature by writing over on F1/F2, and let the EHS use the Water Law to achieve the target temperature.
I have the remote, however the remote controller reports the temperature from where it is installed.
Any ideas how I could do that? Any opcode that represents that?
I was thinking as a workaround to connect to F3/F3. However that seems a bit more complicated, it's not "plain" RS485, seems like it is a Power Line Communication (PLC), since the remote also gets power over the same two wires.
Any ideas are more than welcomed
