The MAC address is only visible in the Home app after setup of the device. You can do this by using the Wifi hotspot feature on a phone or tablet. Note you will need 2 devices to set this up.
- Turn on the Wifi hotspot feature on a phone or tablet. If you're not sure how to do this, refer to the manufacturer's support website.
- Connect a second phone or tablet to that Wifi hotspot.
- You can then use that second phone or tablet to setup your device and connect it to the Wifi hotspot on the first phone or tablet.
Chromecast with Google TV uses MAC address randomization. To stop the Wi-Fi MAC address randomization, you need to go to the Chromecast's settings on the TV itself and disable the "Use randomized MAC" option. Here's how:
- On your Chromecast, go to Settings > Network & Internet > Wi-Fi.
- Select the Wi-Fi network you want to change the MAC address for.
- Scroll down and select Advanced.
- Under "Privacy," uncheck the box next to "Use randomized MAC."
- Select Save.
Once turned off, open the Home app, tap the device in the Home app > Settings cog > Device information, where you'll see the MAC address at the bottom. Give this MAC address for whitelisting. Once whitelisted, it should connect to the Wi-Fi. Do note however that even then your phone or tablet may not be able to communicate with your Chromecast due to the security restrictions applied on these kinds of shared Wi-Fi networks.
