    hmm, I expect something in ZBS menu :)

    it looks that sometimes QA will not work in HC3L or Yubii without visible reason :(

     

    Yes, lots of issues with 32bits integers. 

    @jompa68had this problem on his Nice box.

    Please login or register to see this code.

    returns -60.0 on the HC3 as expected, but 0.0 on the "nice" box. 

    We are adding a small decimal to a rather large integer, but the result is still unexpected....

    Took quite some time to hunt down that bug...

     

    Sometimes in ER the offset to os.time() happen to turn into a float (happens easily in some cases)...

  • More people are starting to code QuickApps using several "QuickApp files". It's convenient to have a library of functions or just structure a code into separate files.

    More specifically, we can share Lua global variables (and function) between QA files.

     

    However, there are some pitfalls.

     

    QA files are more or less loaded in random order.

     

    When all files have loaded, the QuickApp object is created and the :onInit() method called.

     

    This means that if you in one file set a global Lua variable. Ex.

     

    foo = 42

     

    and in another file set another global that depends on 'foo'

     

    bar = foo+55

     

    it will depend in what order the QA files are loaded.

     

    The order they load seems to depend on in what order they are created - not strictly in top-down order. It seems like they always load in the same order until you add or remove a file, then you can get another order.

    This means that bugs can appear months after the QA have been working flawless... just because something innocent was edited in a QA file.

     

    So, be careful with global Lua constants defined in separate files.

    Be careful with classes (QuickAppChildren etc) defined in separate files (they are global values).

     

    In general it's a good practice to not use (reference) any global values until you have entered the :onInit() function. Exeption is of course if there is only one QA file - then you just follow the Lua scope rules...

    It could be perfect to have possiblity to setup order in Main file ...

    attached small toy QA to check internet, reconnect wifi, and enable/disable wifi (which actually is better when one use more than one wifi, so HC will chose itself the working wifi when radio is again enabled).

    Check internet need to be called from TriggerQA or scene or any other loop, i decided to not implement anything here to let open to user how to check.

     

    The QA value is true/false, depending on internet state.

    Get WiFi UUID need to be clicked once in order to be able to use reconnect WiFi

    Disable / Enable WiFi RF is more automatic, as described above.

  • Playing with the new com.fibaro.multiPositionSwitch type. Tip from @Krikroff.

    Can't emulate the UI updates yet, but can be deployed from the emulator to the HC3.

  • The multiPositionSwitch is like a global variable enum. It has a number of positions or states that it keeps in the property 'position'. It was difficult in the past to have a QA of this type as there was usually no suitable property for a string value.

    The current position button is also highlighted (blue).

    Scenes can also easily trigger on position changes.

    It is also a bit dynamic when it comes to displaying buttons for positions as they are updated when the availablePositions property is updated.

     

    Mapping to QuickApp function I would probably code like this

  • Here is an example  how to use  the multiPositionSwitch as a simple TimeOfDay state switch using the EventRunner QA.

    It's interesting as the StateQA used is just one line - the smallest useful QA I've written so far...😊

    How it can be edited? Meaning different Breach points and house layout.

    take your house layout

    tile it to section (of interest)

    save sections as dotted and not dotted png files

    convert files to base64 code

    paste base64 code to QA

  • So I have lua code  that takes a directory with tile .pngs and create a QuickApp file that can be included in the QA

    Please login or register to see this spoiler.

     

    The files in the directory should be named 

    <name>_<index>_<tag>.png

    Ex. "myFile_1_base.png"

    'tag' is the layer. It can be "0","1","2","3"... or whatever. You need to have a layer that is called "base" or "0".

    'index' is the tile number, starting with 1 in the upper left and going right and down.

     

    You also set a row constant that is how many rows the map  is divided up in and the outputFile is the name of the generated QuickApp file.

     

    I use a Mac program, PixelMator Pro' to divide up the picture into tiles. I can turn on and off various layers before exporting the tiles making it fairly simple.

     

    When the QA file is loaded in your QA you have a ImageMap class defined that helps you render the map.

    An example QA like I posted earlier then look like

    Yeah, combining HTML generation with HC FQA Lua stuff and imaging conversion, throw in some base64 coding...

     

    That's next level coding!

    This is mindblowing cool 🤩 tand combined with the Alarm - wauu

    I installed PixelMator Pro - i found a Hires PDF of my house . 

    so next step ...

    What should the resolution be for the PNG files?

    Also can I do 5x3 tiles? or is there a limit?
