motion sensor via input & timer

[asm-technics]

Hi,

I have connected an motion sensor (not Shelly) via the input on a Shelly 4 Pro.

If the input goes HI the lamp goes on, after a programmed time the lamp goes out.

So far so good.

 

If we put the lamp on with the Shelly App, the same thing happens.

But we want that the lamp stays on, if we put it on via the App.

How can we do this without a premium account.
