Hi all,

The first public test version of **Sentinels** is out, and I’m looking for testers. Sentinels watches the devices you already have in Homey and tells you what they are doing: when a pump runs and for how long, when a door is left open, when the voltage drops, when a sensor goes quiet.

It is **read-only** : it never sends a command to any device. It needs the Homey API permission (`homey:manager:api`) only because that is the only way to read devices that belong to other apps. Everything runs locally on the Homey, with no cloud account.

**Current features**

- **Activity monitors** : turn a power reading into cycles, duration and energy (pump, freezer, washer). The on/off threshold is learned from Homey Insights.
- **State monitors** : doors, lights, motion sensors, and appliance states such as “Running”.
- **Voltage monitors** : under and overvoltage per phase, one alert per incident.
- **Groups** : “are all doors closed?”, fired the moment one member is wrong.
- **Availability** : finds devices that stopped reporting, went unavailable or have a low battery. Nothing to set up.
- **Alerts for the unusual** , compared with each monitor’s own history:
  - Still running long (while it is still running, at N x its usual cycle)
  - Cycle unusually long, Cycle count reached
  - Usually does not start in this hour
  - Has not been active for N hours, Has a reading in the last N minutes

- **Any …** choice on every trigger: one Flow covers all your monitors.
- Ready-made messages in 10 languages, including Portuguese (Brazil).
- A Settings page and six dashboard widgets.

**Current status**

Version 1.0.11, test channel. Homey Pro with firmware 12.4.0 or newer. I run it every day on my own Homey Pro with 2 activity, 2 state and 3 voltage monitors and 4 groups covering 43 devices.

**Install the test version**

> **[Sentinels | Homey](https://homey.app/en-us/app/com.gpm.sentinels/test/)**
>
> Observes existing devices and turns capability updates into activity, cycles, energy and statistics. Read-only — it never controls the devices it monitors.

Open source, MIT license. Contributions are welcome: bug fixes, widgets, translations, documentation. `CONTRIBUTING.md` explains how to run the tests without a Homey.

**What would help most**

- Appliances that report a state (“Running”, “Idle”) instead of on/off
- Large homes with many devices and groups
- Widgets on different phones and in dark mode
- Battery sensors and devices that go quiet for long periods
- The ready-made messages in Danish, Dutch, French, German, Italian, Norwegian, Spanish or Swedish: do they sound natural?

**Known limitations**

- Flow cards and the Settings page are in English only. The messages the app writes follow the language you pick in Settings.
- Cards that return numbers (statistics, reports) only show in Advanced Flow. That is a Homey rule.
- Widgets do not work in the Homey web app.
- Alerts that compare with “usual” need a few finished cycles first (5 for the usual duration, 20 for the usual hours).

**When reporting a bug**

Please post here or open a GitHub issue with:

- Homey model and firmware version
- Sentinels version
- The monitor type and the device (and which app it comes from)
- What you did, what you expected, what happened
- The log: turn on **Detailed log** in Sentinels Settings, repeat the problem, then send a diagnostics report from Homey and post its code

Thanks for testing!
