AEMO NEMWEB Quick Reference

This integration provides basic yet reliable AEMO spot and forecast data values. It uses NEMWEB as data source, with a focus being on speed of data fetch. It checks for new data each minute while in standby, and upon the commencement of the 5th minute it will speed up to checking for updates more rapidly, until new data is found (at which point it will slow down polling again to each minute).
