Make your home look lived in while you are away.
Absence Simulator watches what your lights, blinds, sockets and media devices
actually do for 30 days. When you are away, it replays that behaviour — the
real rhythm of your household, not a timer.
WHY IT LOOKS REAL
A timer switching the living room on at 19:00 every evening is a pattern anyone
watching for a few days can read. This app replays a genuinely recorded day
instead:
- It picks one recorded day and reproduces it, rather than averaging several
days into one implausible evening of constant activity.
- It prefers a day with the same weekday, because Tuesdays look like Tuesdays.
- Anything that happened around sunset is re-anchored to tonight's sunset.
Around the equinoxes dusk shifts by nearly an hour across the thirty days the
app remembers, so a light recorded at dusk three weeks ago still comes on at
dusk tonight rather than an hour too early.
- Every event is shifted by a few random minutes, so no two evenings are
identical.
- Before replaying, it puts your devices into the state that day started in —
so a room that was already lit does not sit dark all evening.
USEFUL FROM THE FIRST WEEK
It does not wait for 30 days of history. If a weekday has not been recorded
yet, it borrows the closest match — another weekday, or another weekend day —
and tells you which. A slightly wrong pattern beats an unlit house.
SWITCHING IT ON
- Manually, with a start button that can run until a time you choose. The next
08:00 is offered by default, for an evening out.
- By planning holidays in advance. Enter "1 July to 10 July" months ahead and
it switches itself on and off. Times of day are optional; without them, whole
days are covered.
- From a Flow, including "start until a given date and time" — so it can hang
off a geofence or a door lock in an Advanced Flow.
Come home early and press stop, and it stays off for that holiday rather than
switching itself back on a minute later.
CHOOSING DEVICES
Built for real installations. Filter several hundred devices by name, type or
zone, and select whole types or whole zones in one click. Every supported type
is listed, including ones you have none of, so you always know what the app can
do. Devices you selected that were later deleted or reclassified are flagged
rather than dropped silently.
SEEING WHAT IT KNOWS
A Data basis panel shows exactly what has been recorded: a calendar of the last
30 days, coverage per weekday, and the daily rhythm of your household. It also
names any selected device that has recorded nothing at all, which is usually a
device ticked by mistake.
PRIVACY
Everything stays on your Homey. The app operates no server and sends nothing
anywhere. Records older than 30 days are deleted automatically. Removing the
app removes its data.
REQUIREMENTS
Homey Pro with firmware 12.9.0 or newer. Homey Pro only — the app needs local
device access.
Available in English, German, French, Italian and Spanish.
PLEASE NOTE
This app is a deterrent aid, not a security or alarm system. It does not
detect, prevent or report burglary, and it depends on your Homey, your devices
and your power supply. Do not rely on it as your only precaution when leaving a
property unattended, and do not reduce any other security measure or insurance
cover because of it. Provided without warranty; see the licence for details.
