    Good afternoon.
    I have a gate controller as attached.
    I need to rework it to make the relay trip time shorter. I suspect maybe some kind of resistor, but I don't know if there is a timer circuit or uC here.
    The problem is that the tuya short circuits the relay for about 1 sec, which causes the gate to open and stop.
    This is a property (defect) of the drive, because if I hold down the exit button on the wall or on the drive controller board for longer, the effect is the same as from the tuya application.
    If additional pictures are needed I will send them.
    Thank you.

    Everything here is controlled by the CB3S WiFi module based on the BK7231N. If you can change the time constant, it is only somewhere in the Tuya app. Alternatively, you can change the firmware, but then this module will no longer work with Tuya, at most it will work with Home Assistant.
    Helpful post? Buy me a coffee.

    Thank you very much for the clarification.
    I have read a bit about it and however the more suitable functionality for me is via the Tuya app.

    I tried with this signal of about 1 sec from the Tuya relay to drive another timer relay module - such a small module with adjustable time via a potentiometer.

    I thought that if I shorted the button via Tuya (about 1 sec), the module would operate for the amount of time set on the potentiometer, which is 0.5 sec.
    However, as long as the button is shorted, i.e. the signal from Tuya, the relay in the time module is shorted.

    Please give me a hint as to how to solve this, keeping the Tuya application.
