Blocky set for X minutes does not work?

[knifto2]

I bought some door sensors, however these sensors only sends an OFF command when the door is opened.

I want an dummy sensor (Schuifpui) triggered ON or OPEN for 30 seconds and put the sensor (Schuifpui-Sensor) back to the ON state (so it is in the right state to receive another OFF command);

So I made this blocky (see attachment).

The dummy switch is set to ON, but never returns to off.

What am I doing wrong?

The 30m block is a time block.
Use the nummer block
