I have created a Simulink model with only a constant value (see screenshot).
Then I execute it by running the following script:
clear
set_param DummyTest FixedStep 1
sim DummyTest
disp(y.Time)
Turns out the step size of the simulation is 0.2 s, not 1 second. What do I do wrong?

The setting of this parameter is dependent. It won't take effect until other settings are in place. You can check the solver type by the following. It must have been been 'Variable-step'.
get_param('DummyTest','SolverType')
After setting the following, you 1 second fixed step will take effect
set_param('DummyTest','SolverType','Fixed-step');

You have set the solver?
set_param('Solver', 'FixedStepDiscrete');
