All Home Assistant platforms are supported by the Tuya integration, except the lock and remote platform. ## Configuration of the Tuya IoT Platform ### Prerequisites - Your devices need first to be added in the [Tuya Smart or Smart Life app](https://developer.tuya.com/en/docs/iot/tuya-smart-app-smart-life-app-advantages?id=K989rqa49rluq#title-1-Download). - You will also need to create an account in the [Tuya IoT Platform](https://iot.tuya.com/). This is a separate account from the one you made for the app. You cannot log in with your app's credentials. ### Create a project 1. Log in to the [Tuya IoT Platform](https://iot.tuya.com/). 2. In the left navigation bar, click `Cloud` > `Development`. 3. On the page that appears, click `Create Cloud Project`. 4. In the `Create Cloud Project` dialog box, configure `Project Name`, `Description`, `Industry`, and `Data Center`. For the `Development Method` field, select `Smart Home` from the dropdown list. For the `Data Center` field, select the zone you are located in. Refer to the country/data center mapping list [here](https://github.com/tuya/tuya-home-assistant/blob/main/docs/regions_dataCenters.md) to choose the right data center for the country you are in. ![](/images/integrations/tuya/image_001.png) 5. Click `Create` to continue with the project configuration. 6. In Configuration Wizard, make sure you add `Device Status Notification` API. The list of API should look like this: ![](/images/integrations/tuya/image_002.png) 7. Click `Authorize`. ### Link devices by app account 1. Navigate to the `Devices` tab. 2. Click `Link Tuya App Account` > `Add App Account`. ![](/images/integrations/tuya/image_003.png) 3. Scan the QR code that appears using the `Tuya Smart` app or `Smart Life` app. ![](/images/integrations/tuya/image_004.png) 4. Click `Confirm` in the app. 5. To confirm that everything worked, navigate to the `All Devices` tab. Here you should be able to find the devices from the app. 6. If zero devices are imported, try changing the DataCenter and check the account used is the "Home Owner". You can change DataCenter by clicking the Cloud icon on the left menu, then clicking the Edit link in the Operation column for your newly created project. You can change DataCenter in the popup window. ![](/images/integrations/tuya/image_005.png) ### Get authorization key Click the created project to enter the `Project Overview` page and get the `Authorization Key`. You will need these for setting up the integration. in the next step. ![](/images/integrations/tuya/image_006.png) {% include integrations/config_flow.md %} {% configuration_basic %} Country: description: Choose the country you picked when signing up.
