Touch screen button press

Hi everybody

I have a dahua indoor unit in my apartment, I want to be able to “press” the open door button when someone calls the doorbell, it appears at the bottom of the screen. I can find only one “capacitive” switchbot and it’s a tuya ble unit so I don’t think I can use that?

I need some way to action the unlock (so for example, if I forget my keys, I can let myself in. )

Has anybody got any ideas ?

I have no chance to get cooperation from the building to use dahua directly…
