All devices must use a unique MAC address (Learn more about MAC addresses here: What is a MAC address?) to communicate with a WiFi network, which can enable the device to be tracked across networks and locations.

In an effort to increase the privacy of users, phone manufacturers have introduced a feature called Private Address. This feature hides the device’s real WiFi MAC address and instead generates a random address - this is the Private WiFi Address.

Can a device have more than one Private WiFi Address?

Yes! Devices will generate a unique Private WiFi Address for each network that they connect to. For example, a device’s Private WiFi Address on your home network will be different from its Private WiFi Address on your favorite coffee shop’s network. Some devices may even generate a new Private WiFi Address every 24 hours.

Why should I disable Private Address?

Disabling the Private Address feature will give you the best HomeAware experience. Many features in the app depend on a consistent MAC address to function properly.

Every time a device changes its Private WiFi address:

• A new device will be detected and appear in the HomeAware app. This means you’ll see two devices in the app, though it is a single device in real life. The device created based on the new MAC Address will be present, and the old one will no longer be present.
• A Primary Device will stop providing accurate presence data. You will need to keep re-assigning a primary device.
• Duplicate devices will accumulate.

Currently, HomeAware does not support a way to merge devices. This is why we recommend turning off Private Address on your devices connected to your home network (the same network that your sensor is connected to).
