Product review (1 stars): Save your money
I was using the device to monitor the temperature and humidity in our home after a new HVAC system was installed because the system seems deficient. 1) The device was working and recording properly, but I couldn't get it to record at intervals more than 1 second, which made the Excel spreadsheets ridiculously long. A tech on here suggested that I send a screenshot of the parameter settings, but he offered no suggestion on where to send it. 2) Suddenly, the device wouldn't connect, and the email wouldn't work, so I deleted the software, downloaded again, and after days of frustration I was able to get the email function to work again with the same settings that I first had, the device connected once, and now it won't connect again. The port for the USB on the device seems wobbly. I bought it a few months ago, but haven't used it much, but it is going in the trash.
