A seasonal home looks occupied when its lighting and shades move on a schedule that varies slightly each day instead of firing at the same minute every night. On Crestron Home, this is done through the Vacation Scheduler: Sequence Quick Actions that chain lighting, shade, and TV steps together with randomized delays, triggered by Scheduled Events that can also be tied to sunrise and sunset. The owner turns the whole routine on or off with a single Quick Action from a phone before leaving or on the way back. Cave Group designs this kind of vacation routine as part of the whole-home automation it plans for seasonal and second-home clients, and getting the room selection and timing logic right is a design decision, not a default setting, worth working through with your integrator before the house sits empty for the first stretch of the off-season.
What does Crestron's Vacation Scheduler actually automate?
Crestron Home's Vacation mode is built from two pieces working together: Sequence Quick Actions that emulate normal daily routines, and Scheduled Events that recall those sequences on a day/time basis. According to Crestron's documentation, a typical sequence might lower the lights and shades and turn on the television at night, using a delay step to add time between actions — for example, turning lights on and then off four hours later (Vacation Scheduler | Crestron Home OS Documentation).
The part that actually sells the illusion is the randomized delay. Instead of a fixed four-hour gap, the installer sets a minimum and maximum delay — Crestron's example uses 5,400 to 7,200 seconds (1.5 to 2 hours) for a television-on, television-off pair — so the action fires at a different moment each time the sequence runs. The same documentation shows a full weekday/weekend example: weekday activities start around 7:00 AM and emulate getting ready for work, an 8-to-10-hour randomized "away" delay, then evening lights and TV with another randomized delay before the room turns off; weekend activities shift later, starting around 6:00 PM. Weekday and weekend sequences run as separate Scheduled Events, each tied to its own day-of-week selection (Mon–Fri vs. Sat–Sun), so the house doesn't repeat an obvious identical pattern every night of the week.
How do astronomic (sunrise/sunset) events fit alongside vacation sequences?
Crestron Home's general Scheduler (the same screen used for any scheduled event, not just vacation routines) supports two trigger types: a fixed Time of Day, or an Astronomical trigger calculated from sunrise or sunset for the property's date and time zone, with an offset of up to 4 hours and 59 minutes before or after that time (Schedule Events | Crestron Home OS Documentation). That matters for a seasonal house because a sunset-based exterior lighting event stays correctly timed across the months the house sits vacant — a fixed 7:00 PM trigger in October is wrong by the time winter solstice shifts sunset earlier, but a sunset-relative event self-adjusts.
In practice this means a vacation design can run two kinds of scheduled events side by side: the randomized interior sequences (lights, shades, TV) described above, which use Time of Day triggers paired with random delays inside the sequence itself, and separate astronomic events for exterior and perimeter lighting — porch, driveway, landscape zones — set to turn on at a sunset offset and off at a sunrise offset. Both event types live on the same Scheduler screen and can be enabled or disabled independently, which is useful because an owner may want exterior lighting running year-round while only enabling the randomized interior sequences for the weeks the house is actually empty.
Which rooms and zones should be included?
Crestron's documentation notes that scheduled events only let you select rooms that already contain scenes — any room with a selected scene shows in blue in the Select Rooms Below menu. That's a practical constraint worth raising with your integrator early: if a guest wing, den, or secondary living area doesn't already have scenes built for it, it won't be selectable for vacation sequencing without that setup work first. A reasonable starting list for a seasonal property is the rooms visible from the street or waterline — primary living room, kitchen, a bedroom with street-facing windows — plus exterior and landscape zones on their own astronomic schedule. Ask your contractor which rooms currently have scenes defined, because that list determines what a vacation routine can actually touch without additional programming.
How does the owner arm or disarm it before arriving?
Crestron's documentation describes Vacation mode as something toggled through Quick Actions on the Crestron Home interface: one Sequence Quick Action enables the Scheduled Events (turning Vacation mode on), and a second disables them. Disabling stops a sequence in progress immediately if a delay step is running, though a Quick Action already recalling a scene will let its fade time finish before stopping. Because these are Quick Actions, they're reachable from the Crestron Home app on a phone, which is the practical workflow for a seasonal owner: turn vacation mode on remotely after departure, and turn it off remotely on the way back so the house reverts to normal live-in behavior before anyone walks in. This kind of remote toggle is one reason Cave Group scopes whole-home automation planning for a seasonal residence alongside the rest of the residential system rather than bolting it on afterward — the same Crestron processor and app that runs daily scenes is what runs the vacation routine.
It's also worth asking your integrator how vacation sequencing should interact with any existing security monitoring layer, since an empty-house lighting routine and an alarm or video monitoring account are separate systems that should be coordinated rather than assumed to talk to each other automatically.
Frequently asked questions
What is Crestron's Vacation Scheduler?
It's a feature inside Crestron Home that recalls Sequence Quick Actions — chains of lighting, shade, and TV actions, separated by delay or randomized-delay steps — on a day/time Scheduled Event, so a house follows a routine that doesn't repeat at the exact same minute every day.
How does the randomized delay actually prevent a predictable pattern?
Instead of a fixed pause between steps, the installer sets a minimum and maximum delay duration; Crestron's own example uses a 1.5-to-2-hour random window between a television turning on and turning off, so the same sequence produces a different timestamp each time it runs.
Can exterior lighting run on sunset timing while interior lights run on vacation mode?
Yes. Crestron's Scheduler supports an Astronomical trigger type, calculated from sunrise or sunset with an offset of up to nearly five hours, independent of the Time of Day triggers used for interior vacation sequences — the two event types can be enabled separately on the same system.
Which rooms can be included in a vacation sequence?
Only rooms that already have scenes defined are selectable in the Scheduler's room menu; a room without a built scene has to be programmed first before it can be added to a vacation routine.
How does the homeowner turn vacation mode on and off?
Through a Sequence Quick Action built specifically to enable the Scheduled Events (turning the routine on) and a second one to disable them, both reachable from the Crestron Home app, so an owner can arm the routine on departure and disarm it before arriving home.
