12 months with normal use.
The expected battery life of the sensors is 12 months with normal use. Based on environmental factors and use, your mileage may vary.
Will I get a warning when the batteries get low?
Yes. There is a "Low Battery" warning in the Wyze app found on the sensor's device page. Need to replace the batteries? Check out How do I replace the batteries in my sensor?
Important: Waiting until the battery dies may result in the sensor being unusable even when the battery is replaced. Replace the battery as soon as you see the "Low Battery" warning.
If a sensor of yours has died and is unable to connect even after replacing the battery, please contact our support team for help.
