I am testing a Dragino LHT65 for an application and noticed that data logging is only keeping 24 hours at a time. When I select the day or week graph it says that “No data is available for this period”. When I select the hourly in the graph, I can scroll out to the 24 hours but nothing past that. Does anyone have tips on how to view the day, week, month… graph data on temp and humidity?
Also, on the exterior temp reading it will not keep record or graph the data. It only gives a real time reading in Celsius. How do I change to Fahrenheit and log ext. temp to utilize in a graph format?
