When i did go to sleep last night an error did occur in debug and this morning the 4th Rule.eval did not run.

UPDATE

Found why the 4th Rule.eval did not run. Should be this, perhaps the error from last night is gone also now.

Yes, the previous rule would give that kind of error. I will see if I can implement more helpful error messages.

I really like the possibility to test all rules with ZeroBraneStudio before place them in a live scene

Thanks, I just pushed a new version with some bug fixes and enhancements.... introduced a bug in the last version that prevented some rule to trigger when running off-line.

Yes, it is *very* convenient to test rules off-line. I especially like to be able to post "fake" events to see how my rules reacts.

Ex. a simple turn on light when sensor is breached

.If I have many sensors I want to test the logic for I make an helper function that automatically makes the sensor safe after a specified time

Please login or register to see this code.

Here I can breach s1 and it will automatically become safe after 30s as specified when created with makeSensor. It will behave like a real motion sensors and extend the 30s window if breached again before.

A reason that I developed the script language was that I want some kind of library of global functions.

The EventScript language I put together is almost a complete language (almost a Lua in Lua) but developing more advanced scripts in it still requires insights into programming in general and can be quite complex. The idea has been more that because scripts are Lua strings I can store them outside the EventRunner scene, lika a Fibaro global or another scene and read them into the EventRunner at startup - something we are not allowed to do with Lua code.

More general, a library with known working script templates can be developed for common automation tasks and easily be instantiated by people that are not so proficient in coding.

Example below are two templates, one that turns on/off a lamp using a sensor, and another template that dims a light up and down when a key is pressed on a keyfob.

This is close to real sharable code, on a home automation tasks level... or like scenes in scenes...

This is still a proof of concept and need some more error checks and storing script templates elsewhere...

Rules

Script rules comes in four flavours, and always contain a '=>'

Please login or register to see this code.

Rules are registered and invoked when matching conditions are met.

Expression given to Rule.eval without an '=>' is evaluated immediatly.

Please login or register to see this code.

@time -- always part of a rule. Run action at time of day

Please login or register to see this code.

@{t1,...tn} -- always part of a rule. Run action at times of day

Please login or register to see this code.

@{catch,t1,...} -- if the first argument in the time parameter list is the constant 'catch' the framework tries to catchup actions that have already passed when the framework starts up

Please login or register to see this code.

@@intervall -- always part of a rule. repeat action at specified interval

#event -- event triggering rule.

'#foo' is a short for {type='foo'}

'#foo{bar=9}' is a short for {type='foo', bar=9}

Please login or register to see this code.

Matching with constraints are allowed in event values and start with '$..'. Variables bound in matching expression available as local vars in rest of rule.

Please login or register to see this code.

'env' -- script variable that is bound the the environment the script is executing in. Specifically env.event is the event (sourceTrigger) that triggered the rule.

Event functions

Delays and rule state 

'once(<expr>)' - onceis a special function that keeps state so that it only returns true if it's argument is true but was false before. This is a convenient way to stop an event from triggering multiple times.

Please login or register to see this code.

This rule triggers whenever the sensor triggers and then checks if it is between 6-8. If that is true the test 06:00..08:00needs to turn false before it will be able to turn true again, effectively only greeting people once between 6-8 when the sensor is breached.

'trueFor(<time>,<expr>)'- forallows for checking if a condition is true for a specified duration.

Please login or register to see this code.

The forexpression needs in this case to be true for 10min before it will return true. First time the expression is true a timer is started that checks in 10min if the expression is still true and then returns true. If the expression turns false during that period, the timer is canceled.

 

'again([<num>])' - Sometimes when the trueFor expression becomes true, one wants to reset the timer to get a new trigger the time again. Typical case is if a door is open for 10min send a notification, and continue to send an alarm for every 10min until the door is closed. So, there is a need to 'tell' the forcommand to re-enable the timer. ¨repeat' does that.

Please login or register to see this code.

This will log a message every 10min as long as the door is open. again returns the number of repetition it has currently done, and it can take an argument how many repeats it should do.

Please login or register to see this code.

In this case it will only repeat 3 times, and the for-timer is not reset. However, the next time the for expression becomes true it starts over again.

'wait(<time>)' - waits specified time before continuing executing expression.  'fibaro:sleep' is not allowed as it stops anything going on in the scene while sleeping. 

Please login or register to see this code.

If device 55 is turned on it waits 10min, then checks if 55 hasn't changed state in the last 10min and if so turns off the light. waitis also useful for writing expressions to test rules.

Please login or register to see this code.

This turns on the lamp at 10:00, off again at 10:05, and then on again at 10:07.

Edited October 23, 2018 by jgab

[jgab 1,600]

So, in the Github repository an 'iOSLocator' scene has been uploaded. The idea is to think about scenes as services, like a service oriented architecture. Scenes can send and receive events from each other (Ah, shows my age, guess it should be microservices these days).

 

Anyway, the iOSLocator scene is based on the EventRunnerLite framework and polls Apple's Find friends service for family members position, and if they changed location it will send events to whatever EvenRunner scene we have told it to send events to. Because it's based on the EventRunner framework the scene can be tested offline like in ZeroBrane to verify that it works.

 

iOSLocator depends on data in the 'HomeTable' to specify people, their Apple accounts, and places of interests. In the beginning of the 'iOSLocator' file there is an example of the structure required.

Please login or register to see this code.

The first 'place' in the HomeTable struct should be the 'home' or base, as it is used to calculate how far away people are. Then all other places of interest. Use, e.g. google maps to get lat/long for places that are important for you. The 'list' parameter is the radius from the lat/long that defines the place.

Note, I changed the coordinates for my home so you can't come after me if your HC2 crashes  

Then in the users list we need to list the people's iCloud credentials so we can log in.

In the 'scenes' part of the structure, we list what scenes this service should send events to. It knows that it's name is iOSLocator so it will send events to the scene iOSClient (that has id 9 in this case).

Every minute it will ask iCloud for the next persons location, which means that if you have 4 persons in the family it takes 4 minutes to update all members. If the iCloud server is polled too often it seems it will start to block requests.

If a person moves outside a place an event will be sent that the person is at place "away".

So, if we have configured the 'iOSLocator' and start it up we can put event handlers in our iOSClient scene (or whatever scene you want to receive the events to). Nothing special has to be configured in the client as the events arrive just like any other event.

Please login or register to see this code.

and we can start to add logic to send notifications or detect if everyone is away or if someone has come home....

Please login or register to see this code.

If there is some complicated calculations to do it is easier define a Lua event handler, like in the example above. EventScript rules should be used for writing short concise rules and Lua event handlers for stuff that need to trigger on events . In fact, if there is more advanced calculations like in this example it works as well to break it out into a normal Lua function as they can be called from EventScripts.

Please login or register to see this code.

Here checkLocation is just an ordinary Lua function helping us to keep track if someone is home or all away.

 

A real presence algorithm would also check sensors and other possible means of detecting people inside the house. This can also be used to send notifications when children come home or arrive at school.

Yes, that was the idea. if _test is false it should call fibaro:getGlobalValue(_deviceTable), and _deviceTable should be set to the name of the fibre global.

So it doesn't manage to read in the HomeTable global. 

Have you set _deviceTable at line 20 to the name of the fibaro global containing the HomeTable?

I've pushed a new version of iOSLocator that checks the value a bit better and quits if it doesn't get a HomeTable config data.

 

If you set _REMOTE to true and add the HC2 credentials you can run the iOSLocator scene in ZeroBrane and it will do fibaro:getGlobalValue to the HC2 and you can debug what value it gets.

Set a breakpoint in iOSLocator on line 108 (iUsers = {}), and step through to see what happens.

Hi,

 

how to start scene with parametres in your script e.g. 

fibaro:startScene(jT.scene.HueCollorEffect,{"1", "192.168.1.245", jT.hue.HueUserZahrada, "colorloop", 254, 2}) 

 

I have found in your wiki:

:start. Start scene. Ex. 66:start = fibaro:startScene(66)

but I don't know where I should place parametres {a,b,c}

 

Thanks

 

My script - but it doesn't work:

  Rule.eval("everyHourRun = {00:00,01:00,02:00,03:00,04:00,05:00,06:00,07:00,08:00,09:00,10:00,11:00,12:00,13:00,14:00,15:00,16:00,17:00,18:00,19:00,20:00,21:00,22:00,23:00})")
  Rule.eval("@everyHourRun & label(Zahrada.Osvetlenizahrady,'sldBrightness')~=0 => log('Run Garden Light Effect');fibaro:startScene(scene.HueCollorEffect,{'1', '192.168.1.245', hue.HueUserZahrada, 'colorloop', 254, 2})")

 

There is another way to achieve things being scheduled at specific intervals.

Please login or register to see this code.

I just changed the interval command '@@' to be drift free. That means that if it starts at the second 15 past the minute it will continue on on that second for every minute and not start to drift. That means that one can use the date() command that is almost a crontab format (it compiles to a code that test the condition very effective). 

Anyway, date('0 10-16/2') means that the test will return true on the '0' minute every second hour from 10 to 16.

To make something on the hour the string is simply date('0 *') - * stands for any hour, the same as date('0 0-23'). Much simpler than having to list all hours with the daily '@' command.

Crontab is very flexible, date('15,45 7-19/3 mon-fri dec,jan') means 15min and 45min past every third hour between 7 and 17 on Monday to Friday in January and December.

The '@@00:01' will run the test every minute (exactly like crontab does) and if the date() test is true it will run the action. This is very flexible.

The day(),wday(),month() functions are implemented with date(). Have a look at any crontab documentation on the net and you will get the gist of it.
