Roller Shutter + Shelly 2.5 with neutral

Hello All, I’d like to ask for your advice.

I currently have a simple wired shutter with a 3 way wall switch (up / down / 0) and line only at the switch with neutral wire inside the wall box. I’d like to automate this a bit by using a Shelly 2.5 (with tasmota inside).

The current directly wired setup is very straightforward: N and L go to the wall switch which has 2 wired outputs (up / down) from the wall to the shutter.

My biggest question mark is what will happend if I decide to manual go up or down with the roller shutter (if you press the up or down button it doesn’t go to 0 postion after you stop pressing it) and after that I decide from tasmota to move in opposite direction. Will it let me to do this action or it prevent from moving the roller shutter - I don’t want to break the shutter roller and I would like to know if the switch I have is okey or should I change it to the one which move to 0 position after you stop pressing the up or down direction buttons.

Thank you in advance for your help!

I don’t want to sound like an ass, but u should have kept the shelly firmware.
I read somewhere there is a protection over physical + software simultaneous inputs.
Not sure about the tasmota firmware
