    Hi, I need help in selecting a solution.

    I have two 24 volt solenoid valves and one 24 volt power supply. I would like to control each solenoid valve independently via the Tuya / Smart Life app, i.e. separate ON/OFF for valve 1 and valve 2.

    Additionally, I am keen to be able to manually control from physical buttons or switches:
    - button/switch No. 1 controls solenoid valve No. 1,
    - button/switch No. 2 controls solenoid valve No. 2.

    It is important that the status is synchronised with the app - if I turn off the valve with a physical button, the status should also change in the app, and vice versa.

    I would also like to add two indicator LEDs to show whether a particular solenoid valve is currently on.

    So, which module should I choose to make it work, how should I wire it up, and do I need to protect something so it doesn't burn out, because I've heard that the valve coils overvoltage themselves when they turn off?

    Under the relay contacts 1 , 2 you give 24V from the power supply and to the valves, diodes in parallel to the valve coil. You have manual control on S1 S2.
