Situation 2: Set up Pi-Hole DNS on Deco.

Before configuration:
1. Have the latest Deco app installed on your mobile phone.
2. Make sure the mobile phone is connected to Deco's Wi-Fi network.
3. Close the Deco App if it is already running in the background.
4. Re-launch the Deco App.

NOTE: Only when your mobile phone is connected to Deco's Wi-Fi network and your account is the owner's account, you can change its DNS settings through the Deco app. Force the Deco app to close in the background and re-launch it aims to clear the app cache.

Here we take Deco M5 as an example.

Enter the Pi-Hole DNS in the Primary DNS blank, and click on Save. Then reboot the main Deco and the Pi-Hole DNS will take effect on the Deco network.
