SDK for remote and offline HC3 development

Recommended Posts

Hi,

I'm trying to convert a HC2 code to HC3. I managed to make all the changes and the code is running in HC3 without any issues (at least as far as I can see).

But when I'm using emulator I'm getting this error:

Any idea why?

    Well, you stumbled on a limitation of the emulator.

    It comes down to that we can't make fibaro.x calls that calls the HC3 from within callbacks of some of the builtin lua functions.

    table.sort and string.gsub are typical such functions.

    The reason is that these functions are implemented in C and when the emulator call the HC3 (to get the value) it will try to suspend the current running thread/coroutine and that's not allowed across C-boundaries.

    The way around it is that I provide pure Lua version of these functions - and I may do that eventually.

     

    However, your code is not that efficient.

    Please login or register to see this code.

     

    The sorting function will be called multiple times to sort the array and it will result in multiple calls to getValue, multiple times returning the same value for the same devices when it call fibaro.getValue.

     

    I would recommend to get all the values before sorting - which is faster (and works with the emulator :-) )

    @jgab

    very strange issue with json.encode() (same problem on HC3 platform)

    in example defining array like

     k={test="test",{test1="test1"}}

    and trying to use

        print(json.encode(k))

    I receive an error:

    (fibaroapiHC3.lua:6190: json.encode, fibaroapiHC3.lua:6124: invalid table: mixed or invalid key types......

     

    While running the same on HC2 it works finds and the output is:

    [DEBUG] 04:31:23: {"1":{"test1":"test1"},"test":"test"}

     

    The problem that some  refreshstate responses have same format!!

  • Yes, the json encoder doesn't allow for "mixed" keys. 

    Either a table should be a key-value table, that is encoded to json with curly brackets "{" ... "}"

    or it should be an array that is encoded with square brackets "[" ... "]"

    Your array is a mix with one key-value and one array entry (on top-level, then if the array entry in itself is a key-value table doesn't matter). It is a valid Lua table but not a valid json table.

    The HC2 json encoder is not a correct encoder and "invents" missing keys. You end up with the string key "1" for your array entry. It's not a encoder in my eyes...

     

    I have never seen the mixed table response from refreshStates - and then the problem should have been json.decode ? The HC3 send the data in the REST request, json encoded and that should not have worked then?

    You have an example?

     Here is a plugin for ZeroBrane studio. 

    Put it in the zerobrane folder, in ZBS/packages/ or HOME/.zbstudio/packages folder (where ZBS is the path to ZeroBrane Studio location and HOME is the path specified by the HOME environment variable)

    Plugin: 

    It's not fully developed yet but has a few features.

    • In ZBS 'Help' menu there are links to this thread, the Fibaro QuickApp manual, and Fibaro Lua Scene manual etc.
    • Under 'File' menu there is a "Create HC3sdk database" command that copies some of the most common resources from the HC3 and stores it in a file in the current working directory. File is named "HC3sdk.db". That file can then be loaded into the emulator when you run a scene/QA by adding the option hc3_emulator.start{loadDB=true}. This only works when running offline, but is a convenient way to have access to "existing" devices and globals in offline testing
    • Under 'File' there is a "Create HC3 backup" that downloads QuickApps, Scenes, Global variables, Locations, and Custom Events to a backup directory - more below.
    • Under 'File' there is a "Download files..." that downloads the selected resource from GitHub  - more below.
    • Under "Edit" there is a menu that inserts in the current window templates for a QuickApps and a Scene with the added hc3_emulator commands needed.
    • There is also under "View" a "HC3 Emulator" command that opens a web page available while a QA/Scene is running.

    Future add-on that would be nice...

    • Upload of Scene to the HC3
    • ...

    "Copy HC3 data..." copies resource info from the HC3 and stores it in "HC3sdk.db". Can be used in offline-offline mode.

    "Download files from my Github into the current directory. Requires HC3 credentials to have been setup. By default I try to load "credentials.lua" from current directory to get the credentials.

    "HC3 SDK templates..." insert a Scene or QuickApp code skeleton in the current buffer to be used with the emulator.

    Deploy QuickApp will build and deploy the complete QuickApp in the current editor buffer to the HC3. If multiple files (like the toolbox) is included it will add this files to the QA.

  • You need to set Lua interpreter to 5.3.  (under Project -> Lua Interpreter)

     QuickApps on the HC3 uses Lua 5.3

     

    (I have just added it to the first post, thanks)

    I am trying to use fibaro.sleep() commands, but the code crushes...  ??? What could be wrong?

  • It could depend on from where you are calling fibaro.sleep....

    Is it from a callback function given to some built-in function like table.sort, or string.gsub ?

     

    Some Lua builtin functions take functions as arguments - however these Lua functions are coded in 'C' and Lua's coroutines don't allow yielding from a lua function cross a C function ....

    I use Lua's yield when a QA sleeps to give time to other QAs to run so I need to do that.

     

    In my new emulator I have started to code the most obvious functions like table.sort and string.gsub as pure Lua functions to get around this when needed.

    Hi,

     

    after moving to a new machine I get

    I looked at line 5934 but there is nothing obvious (the line starting "crc="):

    For what it's worth, here is some example code that fails, but as mentioned, any code fails:

    I should mention that I downloaded the latest version 0.315 of fibaroapiHC3.lua; on the previous machine I had an older version, I guess, but I cannot say which one (HDD dead).

     

    Thanks,

    Set Lua interpreter to 5.3 - needed for QAs. 5.3 introduced bit operators like << and >>.

    There is an option in ZBS in the Project menu,.

    A Telegram QA. This QA makes it easy to send telegram messages or create bots.

    Please login or register to see this attachment.

    Two quickApp variables need to be setup

    'BOT_ID' that is the id of your Telegram BOT

    'Users' that is a json table with verified users

    Ex.

    Please login or register to see this code.

    To send a message call the QA

    Please login or register to see this code.

    user can be the username string or the table {name=<username>;id=<id>}

     

    hi jan,

     

    I still have problems using Telegram. 

    To be absolutely sure, the variable BOT_ID cobtains the channelnr and token in the format 123456789:AXJVBF VIIB8FJGNBHFJB (randomly picked), the 1234567899 is the chat_id

    The users variable (when using 1 user) contains a rondom username? Or the botname in telegram? and the number after the : is again the chat_id of that specific bot??

     

    thanks,

    Is this what you need?

    bot id "1490xxxxxx:AAFwEDVm6bbfbfbvbvdvbNcxU4043-lj80"

    user 
    {"Lxxxxxxxxx":1490xxxxxx}

  • Ok, otherwise you can use the telegram bot here

     

    it's enough to set the BOT_ID qa variable.

     

    You can also use it without ER
