Description
Hello! I have automatic setup on my RPi finished without any errors (except service not running) and I can run manually HueEmulator.py script and access web UI without any problems but my hue-emulator.service won't start and I don't see any errors in service status, just inactive (dead).
sudo systemctl start hue-emulator.service just hangs and nothing happening...
Errorlog:
sudo journalctl -u hue-emulator.service

What DiyHue version(branch) are you using?
master (latest)
No errors in syslog? What happens if you execute sudo /opt/hue-emulator/HueEmulator3.py --debug ?
Can you help me with syslog? How to check it?
It looks like this is working fine if you start it manually. When executed as service it must log in syslog (most likely /var/log/syslog). Check this file with tail -f /var/log/syslog while you start the service from another console (sudo systemctl start hue-emulator)
Nothing in tail -f /var/log/syslog while i start the service...
try also sudo journalctl -u hue-emulator.service
As I've mentioned in my bug report - there is nothing in sudo journalctl -u hue-emulator.service
I've tried to comment out all Thread() lines in HueEmulator.py for test service start - doesn't work anyway. How I can check what's wrong with this service script in other way?
I have no clue why nothing is logged. Have you tried to reinstall the application? Ensure you have the content from here in the systemd service file and do a systemctl daemon-reload to be sure it is applied.
Any exit code specified in the service status?

I've checked shebang in .py script and I've added absolute path to service file like ExecStart=/usr/bin/python3 /opt/hue-emulator/HueEmulator3.py and tested it before in cli via sudo /usr/bin/python3 /opt/hue-emulator/HueEmulator3.py and still no service start and silent journalctl. How I can add any logger lines like "IM HERE 1111" to the script just for testing?
I guess the Hue Team are closing down this DIY project... I am running the system on older versions... The new versions don't work for me.
They cannot close the project because Hue Essentials will continue to support it and on Android you can install the last apk version that don't require cloud account.

OK, UPDATE:
I've commented out After line in [Unit] section and service can run now without any problems.

There is an issue with your installation because it never reach runlevel 2. Probable more services are not starting...

Unix & Linux Stack ExchangeI have come across a .service that contains the following:[Install]
WantedBy=multi-user.target
The original .service file can be found HERE.I am on Ubuntu 16.04LTS.
