Use a working GENMON installation and a CentriConnect monitor registered in MyPropane. Have your Device ID, Device Authentication Code, and User ID ready.
The current add-on requires all three values. In the MyPropane app, open Settings → Integration to access the details for your registered device. Contact Centri support if you need help.

- Open GENMON’s Add-Ons page and enable Centri My Propane External Tank Fuel Monitor.
- Enter your Device ID, Device Authentication Code, and User ID.
- Keep Poll Frequency at 288 minutes or longer. The current add-on enforces this minimum, which is within the API limit of one request per device per hour.
- Save the settings. After GENMON restarts and retrieves a reading, look for the fuel gauge on the main interface.
Choose your notifications
- Check Sensor Battery: sends a notification when the monitor reports a critical battery level.
- Check for Missed Readings: notifies you if no reading has arrived for more than 50 hours by default.
Configure outbound email in GENMON’s Settings if you want email notifications.
To adjust the missed-reading threshold, set a positive whole number of hours with reading_timeout in /etc/genmon/gencentriconnect.conf. This value is separate from the polling interval.
# In the existing [gencentriconnect] section
poll_frequency = 288
reading_timeout = 50Understand reading frequency
Centri devices report 4–6 times per day. GENMON retrieves the latest available data; querying more often does not trigger a new device reading.
Keep requests at least one hour apart for each device, including requests from other applications using the same device.

GENMON is a community project. Refer to its current documentation for the version you have installed.
