Uptime alerts with ntfy push
Publish alerts to an ntfy topic, on ntfy.sh or your own server, and get them as push notifications wherever you subscribe.
Set it up
- Install the ntfy app on your phone or desktop and subscribe to a topic with a name that is hard to guess.
- In OpenUptime, open Alerting, choose Add channel and pick ntfy.
- Enter the server (https://ntfy.sh by default) and the topic, plus an access token if the topic is protected. Pick a priority from 1 to 5.
- Save, then press Test: a test message arrives within seconds, and the delivery log below the channels shows whether it went through.
What arrives

Good to know about ntfy
- Topics on ntfy.sh are public to anyone who knows the name. Use a long random name, or a protected topic with an access token.
- Messages are kept under ntfy's 4,096-byte limit so they arrive as text, not as an attachment.
- A self-hosted server must be reachable on a public address.
On every channel
- Every channel is available on every plan, Free included.
- Choose per monitor which channels it alerts, or turn a channel on for every new monitor.
- Until someone acknowledges an incident, it can repeat on the mobile app (up to 10 times, by email too if you choose) and escalate to other channels in up to 3 levels.
- A failed delivery is retried, and the delivery log shows what was sent to which channel and why anything failed.

Questions
What does the priority change?
ntfy maps 1 to 5 from min to max. Priority 4 and 5 can make a sound and vibrate even when the app would otherwise stay quiet, depending on your phone's settings.
How is this different from the OpenUptime mobile app?
The app reaches every workspace member who installed it, and it is where repeat reminders go. ntfy suits people who already use it, or Android users without the iOS app.
ntfy 宕机推送告警
把告警发布到 ntfy 主题（ntfy.sh 或你自己的服务器），在任何订阅了它的地方收到推送通知。
配置步骤
- 在手机或电脑上安装 ntfy 应用，订阅一个不容易被猜到名字的主题。
- 在 OpenUptime 中打开“告警”，点击“添加渠道”，选择 ntfy。
- 填写服务器（默认 https://ntfy.sh）和主题；如果主题受保护，再填写访问令牌。优先级可选 1 到 5。
- 保存后点击“测试”：几秒内就会收到一条测试消息，渠道列表下方的投递记录会显示是否发送成功。

关于 ntfy 的说明
- ntfy.sh 上的主题对任何知道名字的人公开。请使用较长的随机名称，或使用需要访问令牌的受保护主题。
- 消息会控制在 ntfy 的 4096 字节上限以内，所以会以文本形式送达，而不是附件。
- 自建服务器必须能通过公网地址访问。
所有渠道通用
- 所有渠道在所有套餐中都可用，包括免费版。
- 可以为每个监控选择要通知的渠道，也可以让某个渠道默认对所有新监控开启。
- 在有人确认事件之前，告警可以在手机 App 上重复提醒（最多 10 次，也可以选择同时发邮件），并最多分 3 级升级到其他渠道。
- 投递失败会自动重试，投递记录会显示发到了哪个渠道、失败的原因是什么。
常见问题
优先级有什么作用？
ntfy 把 1 到 5 对应为最低到最高。优先级 4 和 5 可能在应用本该静音时也发出声音和振动，具体取决于手机设置。
这和 OpenUptime 手机 App 有什么区别？
App 会通知安装了它的每个工作区成员，重复提醒也只发到 App。ntfy 适合已经在用它的人，或者用不了 iOS App 的 Android 用户。
