What can I do if I receive a low-battery push notification on my SW-A2?
A low-battery push notification will be sent to your mobile device to notify you that the batteries in your SW-A2 have almost depleted. You may need to replace the batteries with two new AAA batteries. After you replace the batteries, we recommend you test SW-A2 to make sure it’s working properly.
For detailed instructions on how to replace the SW-A2 battery, please refer to "How do I replace the batteries in the SW-A2 sensor?”
