Service fails to start on ubuntu 18.4

[realjax]

Used

make install #installs tuyagateway as a service

to create the service, but the service failed with error:

Working directory path '' is not absolute

After editing the .service file and entering a full working path, this error dissapeared but it still fails to start with this output:

Note: when running

python3 main.py

nothing happens.. is that normal?

It could be normal. Check the log levels https://github.com/tradeface/tuyagateway/wiki//Commandline-options

[realjax]

How do I use those command line options with

python3 main.py

? or is that similar? In which case according to the docs it should be set to INFO by default right?
