Can you open a rooflight from your phone?
Yes, on most current systems. Keep a physical switch as well.
Part of our Electric and Opening Rooflights guide
Yes. Most current systems integrate with the common home automation platforms, giving app control, voice control, schedules and automation.
What it enables
Remote operation, which is genuinely useful: closing a rooflight from the office when the forecast turns.
Scheduling. Open for a purge in the early morning when outside air is coolest, close before evening.
Automation on conditions. Open when a room passes a temperature, close on a humidity or weather trigger. On a south facing kitchen that is the most useful of the lot.
Grouping. Three rooflights operated as one, or individually.
The dependency
A rooflight that opens by app is a rooflight that does not open when the hub is down, the network is out, or the manufacturer changes something.
None of those is unlikely over the twenty five year life of a window.
So a physical wall switch alongside it is not a luxury. It always works, anyone can use it without being shown, and it does not depend on anything.
What to run at first fix
The supply to the rooflight, a switch drop to a sensible wall position, and the rain sensor cable if one is likely. All trivial before plasterboard.
Rain sensors still matter
An automation acting on a forecast is not the same as a sensor acting on actual rain. Keep the sensor regardless of what the app can do.
Bedrooms
A rooflight programmed to close on a rain trigger will do it at three in the morning if that is when it rains. Set automations to daytime only if that would wake you.
Yes, on most motorised systems
Manufacturers offer app control either built into their own control gear or through an integration with a smart home platform. A motorised rooflight can be opened, closed and scheduled from a phone, and grouped with other windows so several operate together.
Where a system supports it, you can also set rules: close at a set time, open when internal temperature passes a threshold, close on a rain signal.
What it is genuinely good for
Night purge. Scheduling a rooflight to open late and close before dawn empties accumulated heat out of a building overnight without anybody having to remember. On a south or west facing extension in summer that is the single most useful thing automation does.
Groups. Opening four rooflights at once rather than four times.
Checking from elsewhere. Confirming a window is shut when you are out.
The dependency worth thinking about
A rooflight that opens by app is a rooflight that does not open when the hub is down, the network is out, the account will not authenticate, or a manufacturer changes something in an update.
Over a twenty five year life none of those is unlikely, and the platform your window depends on today may not exist in that form in fifteen years. Roof windows outlast consumer electronics comfortably.
So app control is worth having as an addition rather than as the only means of operation.
What to insist on alongside it
A wall switch. Always in the same place, usable by anyone without being shown, works when a battery is flat and when the internet is not. It needs a cable, which is why it has to be decided at first fix, and it belongs beside the light switches at the room entrance.
A rain sensor wired to the unit itself rather than depending on a weather service over the internet. A local sensor closes the window because it is raining on it, which is the behaviour you want.
A manual override. A crank or release so the sash can be closed by hand. Find out at handover which yours is and keep the crank somewhere memorable.
Solar units
Most solar powered openers work with the same app systems, and they keep working in a mains power cut, which is one more reason they suit a retrofit.
The battery is a consumable good for several years and it is replaceable.
The rule worth following
Treat app control as an addition rather than as the means of operation. Specify a wall switch, a local rain sensor and a manual override alongside it.
A roof window lasts twenty five years. Very little consumer software does.
Ask us
Tell us which platform you already use and we will tell you honestly whether the units we would specify integrate with it, and what happens when it does not. There is no charge for a question.
What we fit as standard
Where a motorised unit is specified we include a rain sensor as standard rather than as an option, and we recommend a wall switch wherever a cable can reasonably be run. App control is offered on top of those rather than instead of them, and we will say plainly at quotation stage which parts of a system depend on a network and which do not.
One last point
Whatever system you choose, make sure somebody other than you can work the window. A rooflight that only opens from one person’s phone is a rooflight that stays shut when that person is away, and in a room that needs ventilating that matters more than the convenience did.
Yes, on systems that offer it
Several manufacturers provide a gateway that connects their control system to a home network, with an app that operates the units and in most cases integrates with mainstream smart home platforms.
That gives remote operation, scheduling, and grouping controlled from the phone rather than only from wall switches and remotes.
What it is genuinely useful for
Closing a rooflight you left open, from somewhere else. Scheduling a purge vent in the early morning in summer, which is the most effective time to cool a house. And grouping several units sensibly without needing a switch for each.
What to think about before relying on it
It depends on the network and the manufacturer cloud service, both of which can be unavailable. The wall switch should still work when the internet does not, and it is worth confirming that on the system you are buying.
The rain sensor is the safety layer and it operates independently of the app. Do not treat remote closing as a substitute for one.
And the gateway needs power and a position, which is easier decided at installation than retrofitted.
