These traits are\nnot tied to just one device type, you can use them as you choose.\n\nThis is the process to add any trait and handle the incoming command:\n\n1. Determine which [trait](/assistant/sdk/reference/traits) you want\n to add.\n\n2. Open the `hotword.py` file.\n\n ```\n cd assistant-sdk-python/google-assistant-sdk/googlesamples/assistant/library\n ``` \n\n ```\n nano hotword.py\n ```\n3. Add the following code block under the existing one that\n handles the `action.devices.commands.OnOff` command (don't delete the existing\n code block).\n\n ```python\n if command == \"action.devices.commands.\u003cvar translate=\"no\"\u003ecommand-name\u003c/var\u003e\":\n if params['\u003cvar translate=\"no\"\u003eparameter-name\u003c/var\u003e']:\n if conditional:\n print('Something happened.')\n else:\n print('Something else happened.')\n ```\n4.

Use a command from the **Device COMMANDS** table. |\n | `parameter-name` | Look again at the **Device COMMANDS** table on the trait page. Each command has one or more parameters associated with it. These are listed under `\"params\"` in the EXECUTE request JSON. Use the exact parameter name. Note that some of these parameters are objects that contain other parameters - just use the top-level object. |\n | `conditional` | You don't strictly need to use a conditional in your handler code, but it may help to differentiate how you execute the command on the device. |\n\n Here are some examples for traits [Brightness](/assistant/sdk/reference/traits/brightness)\n and [ColorTemperature](/assistant/sdk/reference/traits/colortemperature): \n\n ```python\n if command == \"action.devices.commands.BrightnessAbsolute\":\n if params['brightness']:\n if params['brightness'] \u003e 50:\n print('brightness \u003e 50')\n else:\n print('brightness \u003c= 50')\n\n if command == \"action.devices.commands.ColorAbsolute\":\n if params['color']:\n if params['color'].get('name') == \"blue\":\n print('The color is blue.')\n else:\n print('The color is not blue.')\n ```\n5. [Update the device model](/assistant/sdk/guides/library/python/extend/register-device-traits)\n with the trait you added in Step 1.\n\n6. Run the modified source code.\n\n ```\n cd assistant-sdk-python/google-assistant-sdk/googlesamples/assistant/library\n ``` \n\n ```\n python hotword.py --device-model-id my-model\n ```\n7.
