ubuntu - 我的 Nest 能否测试本地设备是否存在，以确定我是否在家？

Question

我有一个 Nest学习恒温器。我认为它会尝试在我离开时使用运动传感器或类似传感器“自动检测”。无论如何，它都不是很准确，更重要的是，它的算法并不透明。

相反，我认为有更好的方法来判断我是否在屋子里......

Nest 在与我的手机相同的子网中提取 IP 地址。

我愿意:

• 告诉 Nest 我手机(和我妻子的手机)的 IP 地址
• 要求 Nest 定期(可能每 10 或 15 分钟)ping 这些 IP 地址以进行在线测试
• 让 Nest 根据这些客观测试更新自己的主场/外场核算机制

这可能通过 Nest API 实现吗？ ？

这是否违反了任何 Nest API Prohibitions ？

这样的客户是否已经存在？

Answer 1

实际上，我想出了如何使用 Nest API 来准确地做到这一点。效果很好!

我创建了一对 Python 脚本，/usr/bin/nest-home 和 /usr/bin/nest-away，它们是 uhome 的一部分我已经上传到 Ubuntu 的包。还有 /usr/bin/uhome 脚本，它处理我的第一个问题——读取 IP/MAC 地址的输入列表，遍历它们以查看是否有任何可 ping 通的，并且基于根据结果​​，标记我们是在家还是在外。

与 Nest 对话的真正魔力在于 3 个后续 API 调用:

1. 登录并建立授权 token
2. 检索结构 ID
3. 更新结构的 away bool 值

完成下面的脚本，或者你可以在 Launchpad 和 Github 中找到它。
