Hi, I just set up the emonPi after not using it for over a year due to moving house. The power inputs/feeds I’d previously set up all worked fine. Then I thought I’d click the upgrade button and now the inputs just say “n/a NULL” where I think they should have a time and a value.
I’m not sure how to start debugging. A couple of things I noticed in the admin:
It can’t find the log file. It says:
The log file has no write permissions or does not exists. To fix, log-on on shell and do: touch /var/log/emoncms/emoncms.log chmod 666 /var/log/emoncms/emoncms.log
I sshed in and the log file appears to be at /var/log/emoncms.log - I tried creating the emoncms subdirectory but it gets removed (on reboot I think?)
mqtt input says mqtt_input Activating Auto-restart
If I run
sudo systemctl status emoncms_mqtt.servicethe output is:
emoncms_mqtt.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead)
I’m not sure how to proceed so any advice gratefully received, thanks!
