is my heat pump supported ?

[ThomasHpc]

Hello,

I get some errors when running the script, maybe my Nibe SHK200M is not supported.

This is from terminal window:

thomas@raspberrypi:~ $ nibe-mqtt -c /home/thomas/config.yaml 2023-05-28 14:40:55,127 - INFO - MainThread - root - Running Nibe MQTT 0.4.0 service with Nibe 2.2.0 lib 2023-05-28 14:40:55,467 - INFO - MainThread - nibe.nibe.connection.nibegw - Starting UDP server on port 9999 Traceback (most recent call last): File "/usr/local/lib/python3.9/dist-packages/nibe/connection/nibegw.py", line 160, in start sock.bind(sockaddr) OSError: [Errno 98] Address already in use

During handling of the above exception, another exception occurred:

Address already in use. Some other program uses the port.

I got it up running now with root access, but the heat pump status indicator goes red now, and no data is received.

In the config.yaml i set model as SMO40 which is the hardware in my heat pump , but the actual model name is SHK200M. Can anything be changed so that the software can recognize my heat pump? This is what the log from the USB on the heat pump:

Something is wrong with your nibegw. It should respond properly to the pump so it won't go into failed state.

[ThomasHpc]

So it doesn't matter that the heat pump controller hardware not is SMO40 but is a SHK200M ?

Before running nibe-mqtt you need to make NibeGW stable so the pump won't go to alarm state. Next step will be already nibe-mqtt. I really doubt that Nibe has a different protocol for your model. Can it be that your model has TCP Modbus as S series pumps?
