Hello
Thank you very much for the great project.
Finally I can integrate the Deye inverter into my smart home. I had first created that with Docker that ran until my Raspi had not found its image anymore. Now I tried to start it via Python3. From "hand" this is also possible but if I want to start the daemon automatically I get this message.
ERROR:root:Error on start: [Errno 2] No such file or directory: 'config.json'.
Can they help me with the problem.

Greetings André

Hi,
that sounds like the program cannot find the config.json file.
Did you rename the sample.config.json to config.json bevore trying to run run.py?
You can validate it using:

python3 run.py --validate

Hi

Many thanks for the help

I had already renamed the config.
The program can be started manually as a daemon. Unfortunately, this only works as long as putty is running.
If I just start it with run.py I get these messages.

I added this entry under rc.local.
python3 /opt/solarman-mqtt/run.py &

Regards

Change this to python3 /opt/solarman-mqtt/run.py -d & and you should be good.
