Hello What light sensor is used on the Rojal S-Timer roller shutter controller? This sensor allows the roller shutter to close partially as the sun shines strongly.

Welcome. Link A little expensive.

You can buy one for a hundred-and-something zloty, but I still have to disarm it, which is why I'm asking what kind of sensor is there, a simple photo resistor or some kind of digital one. Here for 150zł, but still too expensive.

As you can see from the photo, the plug has 4 contacts. It can successfully be VCC, GND, TX, RX. It is difficult to tell from the photo. Disassemble the controller then you will know how the communication is.
