Anda dapat menambahkan sebanyak mungkin karakteristik ke model perangkat. Sifat-sifat ini adalah
tidak terikat pada satu jenis perangkat saja, Anda
dapat menggunakannya sesuai pilihan Anda.
Ini adalah proses untuk menambahkan karakteristik dan menangani perintah yang masuk:
Menentukan fitur yang Anda inginkan
untuk ditambahkan.
Buka file hotword.py.
cd assistant-sdk-python/google-assistant-sdk/googlesamples/assistant/library
nano hotword.py
Tambahkan blok kode berikut di bawah blok kode yang sudah ada
menangani perintah action.devices.commands.OnOff (jangan hapus perintah yang sudah ada
blok kode).
Temukan informasi yang Anda perlukan untuk setiap variabel dalam blok kode di atas.
command-name
Buka halaman ciri khusus dari
Langkah 1 (misalnya, ColorTemperature).
Gunakan perintah dari tabel Device COMMANDS.
parameter-name
Lihat kembali Device COMMANDS.
pada halaman karakteristik. Setiap perintah memiliki satu atau beberapa parameter
yang terkait dengannya. Ini tercantum pada "params" di EXECUTE
meminta JSON. Gunakan nama parameter yang tepat. Perhatikan bahwa beberapa dari
parameter adalah objek yang berisi parameter lain - cukup gunakan
level teratas.
conditional
Anda tidak harus
benar-benar menggunakan
dalam kode pengendali, tetapi mungkin akan
membantu membedakan cara mengeksekusi
perintah di perangkat.

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.
