Air Vent Damper Actuator Motor

Hi all

I have a fan controlled by a D-Link DSP-W115 smart plug

I would like to open an inline air damper when fan is ON and close it when fan is off

I am looking for a stand alone “normally closed” (spring return) damper Actuator or some kind of quarter turn servo motor

But every thing is so huge and expensive.
Maybe a Car Heater Door Motor would do?

Any ideas ?



Found 22$ Electric Air Duct Damper

Along with 12$ four channel wifi relay HLK-SW04
