Can you determine which is correct, your display or your Samsung? Also, if you log into your account on a computer, does that data reflect correctly? I have reviewed your historical data and did not see any gaps in data on your account which could account for data inaccuracies between the two devices. If you find the data on your display is not correct, relocating the display may help correct that; if the data on your dashboard/smartphone is incorrect, relocate the smartHUB away from your router to try and get a better connection from the sensor.
Should you have further questions, please contact us again. Have a great day!
