Should be:

ExecStart=/usr/bin/python /var/www/emoncms/scripts/services/service-runner/service-runner.py

as now it tries to run without redis module. also script should be updated to be compatible with python2:

/opt/openenergymonitor/EmonScripts/install$ python /var/www/emoncms/scripts/services/service-runner/service-runner.py File "/var/www/emoncms/scripts/services/service-runner/service-runner.py", line 23 print("Connected to redis server", flush=True) ^ SyntaxError: invalid syntax

or second solution

sudo apt install python3-pip sudo pip3 install redis

if the second solution will be prefered, then I suggest installing all pip3 modules, not pip (python2) modules in which way now script acts.

Please include in code :)

These have now been updated to use python3: https://github.com/openenergymonitor/EmonScripts/blob/master/install/main.sh#L64 https://github.com/openenergymonitor/EmonScripts/blob/master/install/redis.sh#L20
