Sensor Trends
...: The value departs from its habit by 3 standard deviations
Sensor Trends
Turn any sensor into a trend: rising, falling or steady, with the pace.
Warning! This app might not work properly.
This app version is currently being tested, and has not yet been reviewed. It might not work as expected.
Be extra careful when installing this app.
Turn any numeric sensor on your Homey into a trend: rising, falling or steady, with the pace and an estimate of when a threshold will be reached. A temperature dropping two degrees an hour does not read like a low temperature, and that difference is what the app makes usable.
The app reads no outside data: everything is computed locally, from your own sensors. Nothing leaves your home. The slope is estimated with the Theil-Sen method, robust to outliers, with a dead band measured on the sensor's own noise: a sensor that is not moving is called steady, never falling.

When...
Compares the reading with what this device usually shows at this hour of this weekday. Silent until the habit is built, a hundred and sixty-eight slots need a few weeks to fill.
Sensor Trends
...: The trend became ...
Fires once the new direction has held for the configured time. A short excursion into noise never fires it.
Sensor Trends
...: 25 will be reached within 30 min
Fires when the countdown crosses below the given time, not on every cycle spent below it. Silent when the slope points away from the threshold.
Sensor Trends
...: ... was detected
The first and second halves of the window slope in opposite directions, a peak or a trough. An overall slope can look flat while hiding one.
Sensor Trends
...: The sensor seems stuck
Homey only publishes a value when it changes, so a dead sensor and a perfectly still one fall silent alike. The delay is set per device, in its settings.
And...
Sensor Trends
...: The confidence is at least 50%
Guards a Flow against acting on a slope that barely exceeds the sensor's own noise.
Sensor Trends
...: The trend is ...
Sensor Trends
...: 25 will be reached before 30 min
False whenever no honest countdown exists: flat slope, threshold already passed, or an answer beyond twenty-four hours.
Sensor Trends
...: The slope is ... 2 per hour
In the unit of the watched value, per hour. A rise of one degree an hour is 1, a fall is -1.
