Data transmission issues
WCRC is currently experiencing a combination of ongoing and new issues affecting data transmission from 17 rainfall monitoring sites across the West Coast region.
Four alpine rainfall sites, relying on radio telemetry have experienced persistent communication issues over the past six months. These sites have been scheduled for upgrades as part of the Council’s Telemetry Network Improvement Project. Repairs and associated radio link and repeater upgrades are expected to be completed in Buller in the next month.
Over the past two weeks, a further 13 sites have stopped transmitting data due to a firmware issue affecting newly installed loggers. Seven of these sites stopped working this morning, likely linked to the widespread One NZ outages which occurred last night. The issue is being experienced nationally and can cause modems to become unresponsive.
Staff will still be able to monitor rainfall internally via backup satellite communications, however this data is not yet available on the website.
Council will continue to actively monitor the performance and reliability of the network on a daily basis and address both the immediate issues and implement longer-term improvements to strengthen the resilience of the telemetry system.
