but if i try to start service i have: /usr/bin/python3 /usr/local/bin/mpp-solar-service -c /etc/mpp-solar/mpp-solar.conf MPP-Solar-Service: Initializing ... MPP-Solar-Service: Config file: /etc/mpp-solar/mpp-solar.conf MPP-Solar-Service: Config setting - pause: 5 MPP-Solar-Service: Config setting - mqtt_broker: 127.0.0.1 MPP-Solar-Service: Config setting - command sections found: 1 Traceback (most recent call last): File "/usr/local/bin/mpp-solar-service", line 11, in load_entry_point('mpp-solar==0.4.3', 'console_scripts', 'mpp-solar-service')() File "/usr/local/lib/python3.7/dist-packages/mpp_solar-0.4.3-py3.7.egg/mppsolar/mpp_solar_service.py", line 52, in main systemd.daemon.notify('READY=1') File "/usr/local/lib/python3.7/dist-packages/systemd/daemon.py", line 39, in notify raise TypeError("state must be an instance of Notification") TypeError: state must be an instance of Notification

i attach my mpp-solar.conf [SETUP] # Number of seconds to pause between command execution loop # 0 is no pause, greater than 60 will cause service restarts pause=5 mqtt_broker=127.0.0.1

It looks like an incompatible python systemd

How did you install the python systemd support? (pip or apt?) can you do a pip show systemd or dpkg -l python*systemd and post results

i think i have installed with pip3

jblance commented 4 years ago

I dont think that version is compatible. I used apt-get to install as per the readme. Can you try that way? Otherwise there may be a way to cater for the different versions (though I currently dont know what that would be...)

Tolmino commented 4 years ago

what version i must install ? i can download it and compile

Tolmino commented 4 years ago

simply made 2 tests: version that install pip3 is incompatible but the one that install apt-get works

jblance commented 4 years ago

yeah the usage of the two is different I used the apt package python3-systemd (which is on pypi as systemd-python)

gianfrdp commented 2 months ago

Hello, I think systemd-python pip package should be a requirement for systemd. I lost 2h today trying to install in venv and configure service

After installing with

pip install mppsolar[ble,systemd]

pip installed "cysystemd 1.6.2", but with this package didn't work.

Jul 07 18:41:20 nuc python3[10970]: You are missing dependencies in order to be able to use the --daemon flag.
Jul 07 18:41:20 nuc python3[10970]: To install them, use that command:
Jul 07 18:41:20 nuc python3[10970]:     python -m pip install 'mppsolar[systemd]'

Finally I found this issue, and installing systemd-python worked.
