This is one of my favorite devices that I have used in many projects.

Motorized Smart Valve Actuator (Valve Sold Separately) Wi-Fi & Bluetooth Electric Water Shutoff Controller Robot Automatically, Tuya Smart & Smart Life App Control, Work with Alexa, No Hub Required.

Here is one example for controlling a smart chicken door showing how I extended the servo actuator with a plywood extension.

The actuator arm swings up in a 90° arc lifting the chicken door via a chain.
