Shelly 1 wiring in old house - openHAB Community

Greetings, I’m trying to install a Shelly 1 to automate outdoor lights in an old house build (build around 1920 in Germany). My problem is that a shelly requires more than two wires, however the light switch that I want to automate only gets 2 wires from the wall (as seen in the image below). Is there anything i could do without ripping the wall open and looking for where the wires come from and go? As well somewhere there do needs to be the connection to the “house” and also the connection
