Ospel Sonata Touch switch and Sonoff R4 Mini WiFi relay - no response

Hi, I have an ospel sonata touch switch controlling the leds in the recess, to this I would like to add a sonoff r4 mini wifi relay, the problem arises during operation as with a normal switch everything works, but with the touch switch it seems as if it does not detect the change of state of the S2 terminal. I will add that the switch does not work without the ks-2 bypass
