[Gateway](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#gateway) # GW Firmware 5.8.15 Release Notes ## Features, Improvements and Bug fixes #### Improved Fan Control Behavior and User Experience - Improved Fan Control Automation behavior to respect fan warming override after equalization. - Fan Control Automation will no longer “de-sync” between the Gateway Node settings and the Cloud settings which required the user to “refresh” fan control settings. - Improved Aeration Mode fan control decision making and user defined temperature operating window behavior. - Fan warming override will no longer be used unless selected for automation. - Improved Gateway Node reliability when NAD and NADH EMC values were not the same. - Disabled idle plenum pressure alerts unless a bin structure has “Load Control” enabled. - Improved fan control mode behavior where the algorithm would consider minimum ambient air allowed but not consider fan warming to make fan control decisions. #### Improved Data Reliability Between the GW and OPI Blue - Corrected Plenum pressure values displaying in fan control history messages. - Corrected plenum pressure values sent to cloud under certain conditions. #### Improved Cable Node Behavior - Cable detection and reading reliability on CN08s has been significantly improved. - Improvements to cable node mapping user experience. - Deployed a fix to remove “phantom” cables available to be assigned to a bin structure after cable hardware was changed. The system will now forget the old cable existed if it is not detected anymore. - [OPIsystems Support](https://knowledge.opisystems.com/en/knowledge/opisystems-support?hsLang=en) - [EPIQ](https://knowledge.opisystems.com/en/knowledge/epiq?hsLang=en) - [OPI Blue](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#main-content) - [Upgrade Procedures](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#upgrade-procedures) - [Blue Seed](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#blue-seed) - [Cable Node](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#cable-node) - [agrimatics](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#agrimatics) - [Fan Node Radio (FNR)](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#fan-node-radio-fnr) - [Cell modem](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#cell-modem) - [Release Notes](https://knowledge.opisystems.com/en/knowledge/opi-blue?hsLang=en#release-notes) - [BLUE Lite](https://knowledge.opisystems.com/en/knowledge/blue-lite?hsLang=en) - [Integris](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#main-content) - [bin file](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#bin-file) - [Troubleshooting Information](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#troubleshooting-information) - [Database](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#database) - [Installation](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#installation) - [Software](https://knowledge.opisystems.com/en/knowledge/integris?hsLang=en#software) - [StorMax](https://knowledge.opisystems.com/en/knowledge/stormax?hsLang=en#main-content) - [Upgrade Procedures](https://knowledge.opisystems.com/en/knowledge/stormax?hsLang=en#upgrade-procedures) - [Update Information](https://knowledge.opisystems.com/en/knowledge/stormax?hsLang=en#update-information) - [Upgrade Procedures](https://knowledge.opisystems.com/en/knowledge/upgrade-procedures?hsLang=en#main-content) - [RTU Upgrade](https://knowledge.opisystems.com/en/knowledge/upgrade-procedures?hsLang=en#rtu-upgrade) - [Moisture Cable](https://knowledge.opisystems.com/en/knowledge/moisture-cable?hsLang=en) - [Cable Node](https://knowledge.opisystems.com/en/knowledge/cable-node?hsLang=en) - [OPI Blue Release Notes](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#main-content) - [Gateway](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#gateway) - [Cloud](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#cloud) - [BLUE Lite](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#blue-lite) - [EPIQ](https://knowledge.opisystems.com/en/knowledge/opi-blue-release-notes?hsLang=en#epiq) - [Advanced Grain Management FAQs](https://knowledge.opisystems.com/en/knowledge/advanced-grain-management-faqs?hsLang=en) - [Temperature Cable](https://knowledge.opisystems.com/en/knowledge/temperature-cable?hsLang=en) - [Temperature/Moisture Cable](https://knowledge.opisystems.com/en/knowledge/temperature-moisture-cable?hsLang=en) - [Plenum Pressure Sensor (PPOT)](https://knowledge.opisystems.com/en/knowledge/plenum-pressure-sensor-ppot?hsLang=en) - [Install Guides](https://knowledge.opisystems.com/en/knowledge/install-guides?hsLang=en) - [OPI Partner and Install Certification Information](https://knowledge.opisystems.com/en/knowledge/opi-partner-and-install-certification-information?hsLang=en) - [OPIsystems Internal Knowledgebase](https://knowledge.opisystems.com/en/knowledge/opisystems-internal-knowledgebase?hsLang=en#main-content) - [Administration](https://knowledge.opisystems.com/en/knowledge/opisystems-internal-knowledgebase?hsLang=en#administration) - [Sales](https://knowledge.opisystems.com/en/knowledge/opisystems-internal-knowledgebase?hsLang=en#sales) - [CO2 sensor](https://knowledge.opisystems.com/en/knowledge/co2-sensor?hsLang=en) - [Fan Control](https://knowledge.opisystems.com/en/knowledge/fan-control?hsLang=en) - [Warranty](https://knowledge.opisystems.com/en/knowledge/warranty?hsLang=en) [![Chill listening crop-3](https://knowledge.opisystems.com/hs-fs/hubfs/OPI_with_Tag_RGB_300dpi_3in_tall-2.png?width=100&height=55&name=OPI_with_Tag_RGB_300dpi_3in_tall-2.png "Chill listening crop-3")](https://advancedgrainmanagement.com/) Copyright © 2026, OPI
