Wiring help for stairway / hallway light (two switches)

I am struggling to find the right way (if possible) to wire a single shelly 1 device to correctly control my hallway lights which are operated using two switches.

I have included a wiring diagram of my set up.

I have seen other posts suggesting to place the shelly above the light but this isn't possible with my setup.

Any help would be appreciated!036986EF-7D46-4F5B-B6BB-FE72DB2FC3BB.jpeg

Your wiring diagram is wrong!

Hey 66er!

Thanks for the input! The diagram itself is correct. I have also attached a picture of the wiring behind one of the switches (both wried in the same way). I have checked using a screw driver tester as I've flipped in the switches (on on, on off, off on, off off).

Any suggestions on if it's possible to wire a Shelly 1 given the set up?

Looking at your link, the economical two way switch looks the "closest". The way I understand it, is taking the output (black wire in my case) from one of the switches to a Wago. Then adding 2 wires to the same wago, one back to the swtich again, and one to output on the Shelly.

Thanks for the help so far!
