Sensor Watchdog

A sensor can stop reporting without anything looking wrong. The device still shows as available, the battery reads 80 %, and your automations quietly stop working. You find out days later, when something doesn't happen. Sensor Watchdog watches each capability separately, so a device whose temperature has frozen while its battery keeps reporting is caught rather than counted as healthy. It learns how often your devices normally report and suggests time limits from what it actually observes, instead of asking you to guess. When an entire integration goes quiet at once, you get one alert about the integration rather than fifteen about sensors that are perfectly fine. Devices that only report when something happens, such as contact sensors and smoke alarms, are never reported as dead for being silent. Their silence proves nothing, and the app says so. During installation Homey warns that this app can manage your entire Homey. That warning follows automatically from the one permission the app requests, and Homey offers no narrower version of it: watching devices that belong to other apps is only possible through the Homey Web API. The app uses it to read, and only to read. It fetches the list of devices, subscribes to device updates so it notices when a device loses connection, and looks up zone names so alerts can tell you where a sensor is. It never controls a device, changes a setting, or touches your Flows.
