The author of this article shares their solution to a problem they had with their freezer door not closing properly. They used a Sonoff TH10 temperature sensor and configured it to send an alert when the temperature reached a certain level. However, they found that they were becoming desensitized to the alerts and wanted a way to be alerted less frequently and involve the rest of their family. They used IFTTT to trigger a web service, which then triggered a Flow. The Flow was designed to check the temperature at regular intervals and send notifications if the temperature remained high. They also implemented a system to cancel the Flow if the temperature dropped back down. The author concludes by mentioning that this solution may not have a direct business benefit, but it serves as a training exercise for using Flow to solve everyday annoyances.
