The GatewayThe Gateway is a simple looking black box with lots of smarts and skills.
It is where the magic of the system happens, it controls how often a sensor is monitored.
It locally stores that data with the time to the nearest second it was sampled and keeps that
information until it has been successfully uploaded to the cloud server.
This allows drop outs of the local Internet or WiFi to not result in a loss of data.
With an attached battery pack, the Gateway could go on road trips in the back of a refrigerated
supply truck and when it returns home, dump the days readings for review.
The SensorsThere are a variety of sensors ELNO supports, the most common are the temperature and door contacts. The water temperature sensor has the water proof sensor at the end of a 2 foot extension. This allows for monitoring items like inside a fish tank.
Sensors are easy to install and relocate as needed, just power on, place inside or near what you want monitored and your are done.
