If in fact the water supplied to your home is experiencing very high temperatures, please contact your water utility company or local plumber. Inspect your Smart Water Shutoff for any signs of thermal activity around it that may be causing a high temperature reading. If your Smart Water Shutoff is directly under the sun on a hot day this may affect the temperature reading that your device displays on your app. Try running some water to bring your temperature reading back to a normal range.
