Note. The first ~2000 posts of this thread is mainly about EventRunner3 that is for the HC2. EventRunner3 is not developed further, but bugs are fixed as they are reported. For HC3, the version is EventRunner4, and is a QuickApp,. Here is a post introducing EventRunner4. Most of the 'Event Script" syntax and commands are still valid and old posts can be of use for new HC3 owners. Here is an example of how to code in a "single instance / event" style. A style I'm using today for all of my scenes. The idea is that instead of having to deal with a new instance being spawned with every scene trigger, all triggers are dealt with from within a single scene instance that is continuously running. It becomes something close to a traditional event loop model found in most modern GUI frameworks. The advantages with coding scenes in this style are: Scene can keep state in local lua variables between scene invocations/triggers Easy to keep different rules/logic in the same scene without causing conflicts, e.g. combining continuous running loops/schedules with immediate reaction on incoming triggers Easy to distribute different rules/logic between different scenes and allow them to communicate Easy to schedule actions to do in the future - that can be easily cancelled if new information is gained. Because the scene is continuously running it doesn't matter if there is a heavy initialisation when the scene starts up (parsing HomeTables etc.) as it is only done once... The framework has extensive support to run and debug the scene offline on a PC/Mac to get things right before deploying the scene on the HC2 (uses HC2 emulator). Offline it is easy to simulate trigger/events to understand if the logic is correct, something that is not always easy to detect in a asynchronous environment. It has publish/subscribe mechanism allowing scenes to exchange events without having to know each other's names or IDs or rely on global variables. It has proven to be easy to integrate with external event/msg based systems like Node-red, where scenes can both send and receive events to node-red and thus extend functionality with Alexa, Google home, Hue etc etc. The framework is available in two version, a 'light' version and a full blow version with a lot of bells and whistles. The latter also supports writing rules in EventScript, a "simple", but very flexible and efficient approach to writing rules that need to trigger things at various times of the day, or trigger on sensors or switches changing states. The implementation of EventScript is built on-top of the single instance framework and the event model and would have been impossible to do in a traditional scene model.

(latest iCalendar) Logger service - part of Supervisor Alarm service - TBD CronRunner - a UNIX like crontab service other scenes can register call-backs with Supervisor - A scene that pings EventRunner scenes and makes sure they stay alive.

The lastest version of the code is kept in my GitHub. The background of this framework and a thread discussing it can be found here, however the code has evolved a bit from when originally posted there. If you are new to EventRunner I don't encourage you to read the posts in the thread chronological, as it contains a lot of outdated information. Instead, the best way to get an understanding of the capabilities of EventRunner is to browse the links in the list above.
