Script to switch OFF

Hello all,

I just learned about scripting as I'm looking for a solution for an issue I have.

I want to setup my shelly pro 3 in such a way that if one of the S terminals gets a pulse, the corresponding output is set to OFF.

I need this so that I can switch on lights with my physical momentary switch in my house but also use the Shelly pro 3 with Home Assistant/Google automations.

The problem now is that if I switch on my light with a shelly output I cannot turn it off with the momentary switch unless I first use a HA/Google voice command or similar.

I want to add a wire from the momentary switch in parallel to the shelly S terminals so that if a pulse is given to that terminal, the shelly knows it has to turn OFF no matter what its current state is.

Thank you for the help!
