A few months ago we received an email from one of our ConnectSense Temperature Sensor customers with the subject line: "Another great use for your sensors."
In the email, Greg explains how his wife, Nancy, told him that they should reconsider going to their cottage that weekend. When Greg asked why, Nancy explained that the power was out.
How did she know the power was out without being at the cottage?
Nancy had received a text message saying that their Temperature Sensor was offline. The only reason the sensor would be offline would be if there was no power for the Wi-Fi router to run on.
Because it was a nice day and Greg and Nancy were not concerned about the temperature at their cottage, they chose not to take action, but rather to just wait until the power came back on. In other cases, such as inclement weather, they would have known about the power outage immediately and could have made a quick decision to check up on the cottage or call neighbors to make sure power lines weren't down or that there was no damage to the house.
Greg then got online and began monitoring the power outage using the recorded temperatures (or lack thereof) from the Temperature Sensor at their cottage.
In the graph to the right, you can see no temperature recorded from about 9pm to 12am. From this, Greg was easily able to see that the power had been out for about three hours. In addition, he was able to determine when the power came back on so that him and Nancy would know when it made more sense to go visit the cottage.
Thanks for the email and sharing another use for the ConnectSense Temperature Sensor, Greg!
