The attribute `ct` returned by your device is not an integer, show me the [entity state attributes](https://my.home-assistant.io/redirect/developer_states).
建议使用多模网关+XiaomiGateway3
请提供开发者工具中的[实体属性](https://my.home-assistant.io/redirect/developer_states)。
- `lumi.sensor_smoke.mcn02` 看起来正常 - `miaomiaoce.sensor_ht.t2` 小米云端接口返回报错`-704010000 Unknown`，原因未知
请提供HA中的状态属性。
@wdmywm3 请提供开发者工具中相关实体的[属性](https://my.home-assistant.io/redirect/developer_states)。
@ilazycat - #534 - #640 该设备([chuangmi.plug.212a01](https://home.miot-spec.com/s/chuangmi.plug.212a01))在云端模式下获取功率数值会比真实数据小100倍，建议通过自动模式或本地模式集成，如果它与HA不在一个局域网环境，请参考 https://github.com/al-one/hass-xiaomi-miot/issues/534#issuecomment-1105475576 自定义实体。
Please try master branch.
