我的Nest能否测试本地设备的存在,以确定我是否在家？

Question

我有一个Nest学习恒温器.我认为当我不使用运动传感器时,它会尝试"自动检测".无论如何,它不是很准确,更重要的是,它的算法并不透明.

相反,我认为有一个更好的方法来判断我是否在家里......

Nest在与我的手机相同的子网上绘制IP地址.

我想:

• 告诉我手机的IP地址(以及我妻子的手机)
• 请定期(可能每10或15分钟)ping一次这些IP地址以进行状态测试
• 让Nest根据这些客观测试更新它自己的主/离账会计机制

这可以通过Nest API实现吗？

这是否违反了任何Nest API 禁令？

像这样的客户已经存在吗？

Answer 1

事实上，我已经知道如何使用 Nest API 来准确地做到这一点。它工作完美！

我创建了一对 Python 脚本，/usr/bin/nest-home它们是我上传到 Ubuntu 的uhome/usr/bin/nest-away包的一部分。还有一个脚本，它处理我的问题的第一部分——读取 IP/MAC 地址的输入列表，迭代它们以查看是否有可 ping 通的，并根据结果标记我们是在家还是离开。/usr/bin/uhome

与 Nest 对话的真正魔力在于 3 个后续 API 调用：

1. 登录并建立身份验证令牌
2. 检索结构 ID
3. 更新结构体的away布尔值

完成下面的脚本，或者您可以在Launchpad和Github中找到它。
