Disable OpenHab & Lightwave RF?

Jon · 6 September 2016 19:23

I don’t use OpenHab or Lightwave RF on my emonPi and I’d like to disable them from running. My emonPi has been running slow at times and one of the things I found was the OpenHab user with Java using lots of CPU. I’d also like to disable Java unless there is something emon that needs it.

I found the “To run openHab at startup” commands for OpenHab and I am guessing doing this (below) will turn off OpenHab.

sudo systemctl disable openhab
sudo nano /etc/rc.local

and then remove

/etc/init.d/openhab start

Does the above seem correct? And how do I disable Lightwave RF and Java?

Yes, the above will stop openHab from starting. To stop LightWaveRF from starting at boot you will need to run:

$ sudo update-rc.d lwrfd disable

and delete the lwrf entry from /etc/rc.local/

          chown -R openhab:openhab /var/log/openhab
          chown -R pi:pi /var/log/logrotate

touch /home/pi/data/emonpiupdate.log
          ln -s /home/pi/data/emonpiupdate.log /var/log/emoncms/emonpiupdate.log
          
          
# Restart random seed process now ~/data RW partition has been mounted 
          sudo systemctl restart systemd-random-seed.service
          
          
# Start / Restart services,they should run happy now log dir's are created
          sleep 3
          service mysql restart
          service redis-server restart
          service mosquitto restart
          service emonhub restart
          service emonPiLCD restart
          service apache2 restart

Just a quick follow-up. The slowness I mention above was not related to the OpenHab or Lightwave RF. It was related to many other things that I will document here:

Thank you!
