Below is a summary of different email alert events and what triggers them.
High Temperature Alarm: An email or SMS alert is triggered by a high temperature alarm from your OPI Blue system, This means that one or more temperature sensors within the grain mass of one of your bins on your system is reporting a grain temperature higher than the set High Temperature Alarm setpoint in that Bin's settings. Any High Temperature alert should be taken seriously and investigated to ensure the necessary steps are taken to mitigate any potential hot spots in the grain or grain loss due to heating.
Temperature Rate of Rise Alarm: An email or SMS alert is triggered by a Temperature Rate of Rise alarm from your OPI Blue system. This means that one or more temperature sensors within in the grain mass of your bins on your system is reporting a grain temperature that has exceeded the maximum allowable temperature increase over a day or week’s timeframe which ever has been set by the user. . Any Temperature Rate of Rise alert should be taken seriously with the necessary action taken as these conditions can be an early indication that your grain is beginning to heat which could lead to hot spots and a potential loss of grain through spoilage.
Offline Gateway Alert: When you receive an email with an Offline Gateway alert from your OPI Blue system, this means that your gateway is not longer communicating with the cloud server. In other words, your Gateway Node is offline. You should take this opportunity to troubleshoot why your gateway is offline. Please read this article for more information on troubleshooting offline gateways.
Gateway Power Loss Alert: When you receive an email with an Gateway power loss alert from your OPI Blue system, this means that your gateway is no longer receiving 110V AC line power from the wall plug it is connected to.
