Sonoff Mini Tasmota relay not working

Configuration
,
1

Hi all,

I’v made my dumb doorbell smart with a Sonoff Mini with Tasmota on it.

I used the wiring from this topic: Making the easiest smart doorbell with Sonoff mini

It is working so far that when I push the doorbell button, the Home Assistant switch turns on. But the physical doorbell chime is not working. It looks like the SonOff Mini relay is not working/on.

I don’t have much experience with configuring it, so I hope someone can help me with it.
I think I have to set SwitchMode 1 but I am not sure and don’t want to break things.

Hi
Replace the panasonic ebg888 with a lamp and press the button to see if light goes on, if you haven’t already tested the button and buzzer connected the normal way.

Thnx, the lamp was working.
The transformator between is was not strong enough, so I should replace it.
