Introduce the daily tasks used to monitor the health and performance of Smart Meters deployed in a FlexNet system using the RNI reports, charts, and tools. The goal of this module is to:
Review: Verifying Endpoint Operation Monitoring Smart Meters Are Meters taking consumption measurements and collecting status data? Are SmartPoint modules collecting usage and status data from meter and putting it on-the-air for the Base Station to pick up? Are there alarms related to resource losses, theft, communications, or function? 2 Meter Ops
Monitoring Meters Using FlexWare Monitoring Smart Meters 2 Note: For RNI metering deployments integrated with Logic or another MDM, use FlexWare to analyze issues found in those tools. Meter Ops
Monitoring Meter Status Section One
Determine the endpoint state of a meter/SmartPoint module. • Determine if a meter has missing or incorrect configuration or manufacturing information. • Determine if a meter has been quarantined. • Determine if a meter is in the RMA process. • Determine which meters are missing reads. • List four potential causes of missed reads.

Identifying Quarantined Meters: Step 1 D Monitoring Meter Status Click Reports > Quarantined Meters View duration of quarantine View causes View date of last invalid message View quarantined messages
Identifying Quarantined Meters: Step 2 D Monitoring Meter Status Review the resulting list: • Listed meters have produced reads that are outside of expected range and are not passed to MDM • Invalid Msg Description column lists the reason why the read message has been quarantined
Identifying Quarantined Meters: Step 3 D Monitoring Meter Status Investigate the meters based on their message Activities that can trigger a quarantine, but are acceptable read values: • Installed a meter at new premise that had been previously installed elsewhere
Primary Causes for Meters with Missing Reads E Monitoring Meter Status Connectivity Issues • Anything that creates a break in communication between the meter and its associated Base Station • Some issues are related to the radio frequency being blocked or of insufficient strength; some are related to equipment configuration or network infrastructure • Short-lived issues may be caused by weather, irregular interference of the radio signal (blocked in some way), excessive buddy messages or alarms, etc. • Long-lived issues are commonly due to backhaul failures or insufficient network coverage
Determining Why Meters Are Missing Reads E Monitoring Meter Status * Covered in next module
Two Categories of Communication Issues E Monitoring Meter Status Non-RF Issues: • System operation and performance • Functional failures of devices • Incorrect configuration RF Issues: • Intermittent or complete lack of communications between the meters and the base stations due to interference, poor signal quality, or network coverage • SmartPoint module or Base Station operation
Identifying Meters Not Communicating: Non-RF Issues Monitoring Meter Status Click Reports > Communication Statistics Look at the Signal-to-Noise ratio (SNR) E Dir SNR describes the signal strength relative to the noise on the signal between the meter and the Base Station Good = 16 dB or greater
Identifying Meters Not Communicating: Non-RF Issues Monitoring Meter Status Evaluate the SNR value: • Good? Continue to next step • Marginal or poor? • Is noise too high? See Diagnostics > FBS Status > Idle Noise • Is signal strength too low? See Diagnostics > Overall System Graphs > Signal Strength Histogram • Idle noise and signal strength graphs are shown in the next module E
Identifying Meters Not Communicating: Non-RF Issues Monitoring Meter Status Look at the Bud Me and Bud Othrvalues • Bud Me is the number of times another meter has used this meter as a communication buddy • Bud Othris the number of times this meter has used another meter as a communication buddy • Evaluate the data: • Is Bud Othrlarge? May have issue with this meter • Is Bud Me large? Indicates multiple meters sending through this meter, may have issue with a Base Station • Both Bud Other and Bud Me are small? Normal, continue to next step E
