Acuparse Troubleshooting Guide



The best way to troubleshoot your install is to view the syslog. All Acuparse output is logged there.

tail -f /var/log/syslog


Access Log

The Apache access log contains all the data Apache has received from the web. Including the readings from your Access/Hub. Checking this log will indicate if Acuparse is receiving data from your devices.

tail -f /var/log/apache2/access.log

Error Log

The Apache error log contains the errors and warnings generated by Apache and PHP. Viewing this log can indicate if something is wrong with Acuparse.

tail -f /var/log/apache2/error.log

Cron Log

You can check for errors running cron jobs in the cron log file.

tail -f /opt/acuparse/logs/cron.log

Sensor ID's and MAC Addresses

Without a MAC configured for your Hub or Access, Acuparse has no way of knowing what data it should listen for. You must set a MAC and 5-in-1/Atlas sensor ID in the admin settings to begin receiving and uploading your readings.

Sensor ID's/MAC addresses are located on the sensors themselves. If you can't locate them, the syslog will report all sensors and MAC addresses it does not recognize.

You can search the syslog for the unknown messages.

cat /var/log/syslog | grep "Unknown"

Cron Job

The cron job is essential for the proper operation of Acuparse. It runs the archiving, update checking, and external uploads. If your station remains offline and/or there are no updates to external providers, there is a chance this is why.

Run the following commands to update your crontab.

crontab -l | { cat; echo "* * * * * php /opt/acuparse/cron/cron.php > /opt/acuparse/logs/cron.log 2>&1"; } | crontab -

To check for Cron errors, see Cron Logs above.

Rasberry Pi's

When you are directly connecting your Access/Hub to a Rasberry Pi, you must change your upload servers to the secondary ones. This is due to the fact that the Pi is redirecting your DNS locally and without changing the upload server, you can end up with a never ending cycle of readings.

See MyAcurite Upload URL's for more details!

Installation Errors

If you experience unexpected results while completing the web install, try removing your config file and retry.

sudo rm /opt/acuparse/src/usr/config.php

In more extreme cases, you may also need to remove and reinitialize the Acuparse database.

Access Device

If your not receiving data from your Access, ensure you have a DNS resolvable hostname set for the upload server and/or a DNS redirect in place. Then, reboot your Access. The Access can at times require multiple reboots to begin sending data.

MyAcurite Offline

If MyAcurite is offline, Acuparse will respond to your Accesss and store your readings but they will not be back filled to MyAcurite after their outage is over. The Access is capable of storing the data and sending it later but when used with Acuparse, the Access will continue to think MyAcurite was online and the readings stored.

You will receive a warning in your syslog when this happens.


The date and time are critical to Acuparse operations. Both on the server and on your Access device.

The Access device will check for NTP on Ensure your Access can connect to NTP here, or redirect your DNS for to a local NTP server.

If the installer was not able to configure NTP for you, review your OS documentation for the proper way to configure NTP on your system.

Google DNS

The Access device appears to be configured to resolve DNS through by default. Testing shows that the Access will query your local DNS for a while, but for currently unknown reasons, will switch and lock onto This could be a way to prevent DNS redirects, but there is no data to support that.

To solve, redirect DNS requests from your Access destined for to your local DNS server in your local firewall rules. Also, ensure your Acuparse hostname set in your Access will resolve through

Cisco Switches

If your Access constantly reboots/reconnects when connected to a Cisco switch, enable Portfast.

config terminal
interface FastEthernet0/XX
spanning-tree portfast

Hub Device

MyAcurite Support

MyAcurite has terminated support for the SmartHUB. Acuparse will receive and store these readings and respond to your hub. Readings will not be uploaded to MyAcurite and will only be stored locally. You can still use the Hub to upload to external providers.
