Changing this bit changes how other EV's are interpreted by the firmware. This may lead to inconsistencies and confusing behaviour. Some EVs may have values that cannot be represented by the Module Descriptor File for that \"event type\". This may happen for an option field where the value does not have an option or the value is outside its min-max range. \r\n\r\nSuggested fixes include making this \"type\" bit read-only once the event is created, or add a rule feature that is triggered when the \"type\" bit changes and when triggered sets some EV's to sensible values for that event \"type\".","author":{"url":"https://github.com/SvenRosvall","@type":"Person","name":"SvenRosvall"},"datePublished":"2024-11-14T11:05:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/40/ModuleDescriptor/issues/40"}
