Open and close blinds with sunrise and sunset
Blinds open a little after sunrise and close at sunset or a fixed bedtime, whichever is more useful for privacy, while the physical remote or wall control still works at any time.
Best for: Motorized blinds or shades with their own reliable open and close commands and a household that wants a predictable daily rhythm without daily manual adjustment.
Not for: Manual-only blinds, or relying on a sunset trigger alone in a street-facing room during long summer evenings.
Why this exists
A fixed clock schedule drifts away from actual daylight as the seasons change, while a sunrise and sunset trigger follows the sun automatically. Privacy, however, does not follow the sun the same way; a bedroom that stays exposed until a 9 PM summer sunset is a real problem, so a fixed bedtime close is worth adding alongside the sunset trigger.

Logic
- Trigger: Sunrise, with a comfortable offset, or sunset.
- Conditions: The blind schedule is enabled. A bedroom may also require the household to be awake before opening.
- Action: Open blinds after the sunrise offset. Close them at sunset, or no later than a fixed bedtime for privacy-sensitive rooms.
- Wait / timeout: None beyond the sunrise offset and the fixed bedtime.
- Stop condition: The blinds reach their commanded position.
- Manual override: The remote, wand, or wall control always wins.
Setup notes
- Group blinds by job: privacy-sensitive, general living space, and solar-gain windows.
- Start with a sunrise offset of 20 to 30 minutes rather than the exact sunrise time.
- Give privacy-sensitive rooms a fixed bedtime close in addition to the sunset trigger, so long summer evenings do not leave them exposed.
- Confirm the physical remote, wand, or wall control still operates each blind after adding automation.
- Test for a full week before assuming the schedule fits the household’s actual routine.
Advanced features
Add a light sensor only when it solves a problem
A sunset trigger is predictable and needs no outdoor sensor. Add a light sensor only if heavy shade, unusual overcast weather, or a specific room consistently needs a different trigger.
Stagger multiple blinds
Where several blinds share a schedule, opening or closing them a few seconds apart can look more natural and reduces the load on a shared hub or gateway at one instant.
Failure modes
- Blinds open too early or too late: Confirm the home’s location and time zone, then adjust the sunrise or sunset offset.
- A bedroom stays exposed on summer evenings: Add or shorten the fixed bedtime close for that room.
- Blinds do not respond: Check the blind’s battery or power, confirm the hub is online, and test the physical remote.
- Blinds move at an unexpected time: Review for a second automation acting on the same blind and remove the conflict.
- The hub or internet is down: Use the physical remote or wall control. Do not make a cloud-only path the only way to operate the blinds.
Done when
- Blinds open at a comfortable time after sunrise for seven consecutive days.
- Privacy-sensitive rooms close by the fixed bedtime even on the longest days.
- The physical remote or wall control still operates every automated blind.
- No blind moves from an automation the household did not expect.
- Someone who did not configure the automation can operate a blind manually.
FAQ
Should blinds open exactly at sunrise?
A small offset after sunrise is usually more comfortable than opening the moment the sun is technically up, especially in a bedroom.
Why close blinds at a fixed bedtime instead of only at sunset?
Privacy matters most after dark regardless of the season. A fixed bedtime close keeps street-facing rooms private on long summer evenings when sunset is very late.
What happens when the hub or internet is down?
The blinds’ own remote, wall switch, or app pairing must still open and close them manually while the automation is unavailable.
