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.

Be extra careful when installing this app.
Estimates how fast each numeric sensor is changing and when it will reach a threshold, using the Theil-Sen method, which shrugs off outliers. A sensor that is merely noisy is called steady, and everything is computed locally from your own devices.

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.

What’s new
Version 1.1.0 — New History widget: a trend's curve over the last hour, 6 hours, 24 hours or 7 days, read from Insights. The Trend tile's curve is smoothed, the device is picked from a searchable list, and the trend resumes right at startup from Insights history, flagging a signal too irregular to be reliable. Danish, Norwegian and Swedish join the languages. The forecast no longer shows 0 at startup, the time-to-threshold card gives the time for its own threshold, and cards no longer fire again after a restart. Widgets now fill the whole tile and offer five backgrounds: deep blue, slate, plum, forest and sand. The tiles share a common layout: category, name, value and details, easier to read at a glance. Very low temperatures, down to −50 °C, stay readable and correct.
