Alexa无法发现自定义智能家居技能中添加的温控器问题求助

针对你提供的设备发现响应JSON，结合Alexa智能家居技能规范，以下是几个关键排查点：

• 必填属性不完整
  Alexa的Alexa.ThermostatController接口有明确要求：

  1. targetSetpoint必须补充支持的温度范围（supportedSetpointRange），仅声明name无法通过校验；
  2. description字段不能为空，需填写设备的简要描述（如"儿童房智能温控器"）。
     修正后的capabilities示例：

  {
    "configuration": {"supportedModes": ["HEAT","COOL"]},
    "type": "AlexaInterface",
    "interface": "Alexa.ThermostatController",
    "version": "3.2",
    "properties": {
      "retrievable": true,
      "proactivelyReported": true,
      "supported": [
        {
          "name": "targetSetpoint",
          "supportedSetpointRange": {
            "minimumValue": 10.0,
            "maximumValue": 30.0,
            "precision": 0.5
          }
        },
        {"name": "thermostatMode"}
      ]
    }
  }
  

• Token字段有效性
  event.endpoint.scope.token为空字符串，虽然发现阶段部分场景允许留空，但建议填入技能授权流程中获取的有效Bearer Token，避免Alexa因验证失败忽略设备。

• 接口版本兼容性
  当前使用的Alexa.ThermostatController版本为3.2，若你的Alexa设备固件版本较旧，可能存在兼容性问题。可尝试将版本降级至3.1后重新测试。

• 基础字段校验
  确认displayCategories中的THERMOSTAT拼写正确（大小写敏感），endpointId保证全局唯一且未重复注册。

你提供的原始发现响应JSON #
