When people ask whether smart curtains save electricity, they usually mean two different things: how much power the motor itself uses, and whether the curtains can reduce the load on their air conditioner. The honest answer is that one of those numbers is tiny and the other is where the real saving is.
The motor uses almost nothing
A curtain motor only draws power in the few seconds it is actually moving, not while it sits still. Even opening and closing several curtains twice a day adds up to a small fraction of one unit per month.
Rated power on these motors sits between roughly 18W and 75W depending on the model, but that figure only applies while the curtain is in motion. A curtain takes a few seconds to cross a normal window, twice a day. Multiply that out over a month and you are still well under a single unit — less than a ceiling fan uses in an afternoon.
Where the real saving is
Yes, but not by the motor — the saving comes from blocking direct afternoon sun so your AC runs less. The motor itself draws almost nothing.
In a Pakistani summer, the biggest heat load on a room is direct sunlight through the glass. A closed blackout curtain on the sun-facing side stops that heat before it gets in, so the room stays cooler and the air conditioner does not have to work as hard.
Can curtains cut your AC bill?
Yes. Closing blackout curtains on the sun-facing side during the hottest hours keeps the room cooler and reduces how hard the AC has to work.
This is not marketing. It is the same reason a car parked in the shade stays cooler than one in the sun. The effect is strongest with blackout or heavy fabric, and on west-facing windows that catch the brutal afternoon sun.
How to make it automatic
Schedule curtains to close on the sun-facing side in the early afternoon and open again after the heat passes, so the room stays cooler without manual effort.
All three of our motors — the Tuya GE82TY, the Dooya DT72TV, and the Dooya DT52E — support scheduled automation through the Tuya or Smart Life app, so the curtains close and open on a timer without you remembering to do it.
The honest caveat
If you have one small window in one room, the savings will be modest — this is not a bill-cutting miracle. Where it genuinely earns its cost is on large windows, west-facing glass, and rooms where the AC runs all afternoon. A curtain that blocks the sun before the room heats up is a curtain that pays for part of itself over time.
