Please note that the non-matter version devices cannot be added to Google Home directly; you will need to add the devices to your U home App first and then link your U home App account with Google Home to achieve this.
Please make sure your devices are connected to WiFi so that Google Home can control them. For those Bluetooth-only smart locks, you will need to pair a Bridge with them and connect them to WiFi network.
Below are the detailed steps to link your U home App account with Google Home:
1. Go to the Devices page of Google Home App and click the "+Add" button; then, please choose "Work with Google Home";
2. Click the search button and search "U-tec Smart Home", click to continue;
3. Input your U home App account and password to log in; click "AUTHORIZE"; then please set up a PIN code, you can also ignore and skip this;
4. Wait for the link process to finish; then select the devices you plan to control via Google Home and add them to a room;
5. Devices will be added successfully; you can see and control them in the Devices page now.
