Unable to control smart home devices in Control Panel when my Huawei phone/tablet is connected to a mobile network

Problem:

When the phone/tablet is connected to a mobile network, the user cannot control smart home devices in Control Panel and a message is displayed indicating that devices failed to be controlled.

Cause:

Smart data saver is enabled on the phone/tablet, resulting in AI Life Service not being able to access the Internet.

Solution:

Go to Phone Manager > Mobile data > Smart data saver, touch the four-dot icon () in the top right corner, select Show system processes, search for the keyword "AI" in the EXEMPTIONS list, and locate AI Life Service and enable it.
