Coverage increased (+0.6%) to 69.054% when pulling c1fd089 on maxekman:feature-109/persistent-scheduled-commands into c4089ff on looplab:main.

Looks great, done scenario testing and it works according to our requirements.

@haderach75 I have changed the API slightly by adding a separate Load() method instead of being part of Start(). Can you please do a quick re-review?
