Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Hi

I am wondering if there anything can automate opening and shutting down water through angle valve?

I don’t think so. There are main shutoff valves and also hot water heaters with a built in smart valve.

Replace with a springloaded pin valve and use an electro-thermal actuator.

Aka, automated radiator valve.

Previously I've achieved similar using an RC Servo with a fabricated bracket.

The reason I didn't use a typical motorised valve is I wanted proportional control of the flow, not just on/off.

If this is a Radiator Valve, there are plenty of off the shelf solutions, replacing the whole valve. Some of them will talk to home automation systems.

Thanks for sharing! Proportional flow control is ideal! It will be great to share some links of the tools/parts that would help me to start this project

I did it by measuring the torque required to turn the valve (using a spring balance on the end of a lever which operated the valve.

Then bought a servo which had about double that torque rating - just so it has some in the bag if needed & won't be over-stressed long term.

I fabricated a bracket for mine - but this could more easily be 3D Printed.

Then used an ESP32 (Arduino kind of thing) to control the servo.

Unfortunately, I have no links or guides for you to follow - you'll have to figure it out as you go.
