Cihaz modelinize istediğiniz kadar özellik ekleyebilirsiniz. Bu özellikler
yalnızca tek bir cihaz türüne bağlı olmadığından, bunları istediğiniz gibi kullanabilirsiniz.
Bu, herhangi bir özellik ekleme ve gelen komutu işleme sürecidir:
Yukarıdaki kod bloğunda her değişken için ihtiyacınız olan bilgileri bulun.
command-name
İlgili özellik sayfasına gidin.
1. Adım (örneğin, ColorTemperature).
Cihaz KOMUTLARI tablosundan bir komut kullanın.
parameter-name
Cihaz COMMANDS'lerine tekrar bakın.
tablosunda yer alır. Her komutun bir veya daha fazla parametresi vardır
görüntülenebilir. Bunlar EXECUTE (Yürürlükte) bölümündeki "params" altında listelenir.
JSON isteğinde bulunun. Parametre adını tam olarak aynı şekilde kullanın. Bunlardan bazılarının
diğer parametreleri içeren nesnelerdir; yalnızca
üst düzey nesnedir.

Koşullu çalıştırmanız gerekmez.

Use the [Google Assistant Service](/assistant/sdk/guides/service/python) instead.\n\n\u003cbr /\u003e\n\nYou can add as many traits to your device model as you wish. 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. Find the information you need for each variable in the above code block.\n\n |------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n | `command-name` | Go to the specific trait page from Step 1 (for example, [ColorTemperature](/assistant/sdk/reference/traits/colortemperature)). 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. Try a query.\n\n *Hey Google, set brightness to 65%.*\n\n *Ok Google, make it blue.*\n\nNext step\n---------\n\n[Register Custom Device Actions](/assistant/sdk/guides/library/python/extend/custom-actions)"]]
