Unfortunatly, the function I have added is no more making the change, {} are still {} after running the function.

What I am using is:

     local function emptyArray(t)

          if type(t) == 'table' then

            if next(t)==nil then json.util.InitArray(t)

            else

              for _,v in pairs(t) do emptyArray(v) end

            end

          end

     end --emptyArray()

 

    emptyArray(climZTable) -- needed for changing {} to []; lauched after all new values control in climZTable table

 

I tried also 

json.util.InitArray(climZTable.properties.incompatibleDevices)

with no success

This function was working with fibemu and hc3emu...

Sorry, InitArray was lost. Added json.util.InitArray in v1.2.43

Hi Jan,
Moving even further with the PLUA, have you implemented the com.fibaro.multiPositionSwitch device type already?

I'm trying to try a very simple QA based on the below.

 

It works perfectly locally on hc3, but not with PLUA Proxy nor Desktop UI.
The issues are:

• The proxy gets the "multiswitch" buttons, created, but not the desktop UI.
• When click on a button the "setPosition(value)" function get a nil value.

Here is the code:

Thanks.

Plua don't support to connect to an existing QA.
The model I to let Plua autogenerate a proxy and when the code work do 
update to update the existing QA.

[petrkl12 228]

OK, Is it possible to do copy of current QA (varaibles, UI) including childs (also vars,UI)?

 

[jgab 2,647]

The way to start is to do a

It downloads the existing QA and unpacks it into lua files and adds the header to the main file.

Then you can add 

--%%proxy:true

and 

--%%logui:true

to get it to use a proxy and log the proxy's ui settings on each start.

@jgab

it could be still perfect to have possibilty to do debugging as in previos version. Do you thing that you could do it?  Thanks

 

hc3_emulator.resources = {UI = 1212, quickVars = 1212}
hc3_emulator.proxy = 1212

Any specific reasons you don't want to create proxy on the HC3 to debug?
The way to hijack an existing QA to insert a proxy handler was not fool proof...

[petrkl12 228]

it's about speed. I don't need to do any action just to start debugging in ZB (perfect solution for me)

Hi @jgab,

Using the desktop view, is it normal that for a switch button it is not possible to change the switch button text  inside the "onToggled" function (except at start, inside onInit()) ?

The code below does not make any change of the switch button label

if event.values[1] == true then

        self:updateView("autoSwitch", "text", "Auto Mode activated")

    else

        self:updateView("autoSwitch", "text", "Auto Mode desactivated")

    end

The above code is working for another normal button.

 

I have also tested your QA example described in your documentation (

Please login or register to see this link.

)

I have the same issue, cannot update the "text" value of the switch button.

 

BTW; it seems that line: self.autoMode = event.values[1] == "true" is incorrect and needs to be changed to self.autoMode = event.values[1]

Yes, it was a miss, fixed in v1.2.48

If you need a way to keep an eye on the HC3 system events while developing, I recommend the EventLogger app.

Dear @jgab,

 

I reopen in vscode lua file that was working Offline few weeks ago but now I am getting this error just after the onInit() has been terminated and I can see for 2 seconds the correct QA desktop view: 

WARNING:plua.fastapi_process:FastAPI process not running

=> process stopped

 

May I have changed something in the plua settings which causes this error?

Fixed : Sorry, I was not lauching the QA with the right launch.json....

Dear @jgab, is the call     fibaro.getFile(id,"fileName")   is existing in Plua?

I want to know if a File is existing in a QA

I am getting this type of error:

attempt to call a nil value (field 'getFile')

No, it’s not. You need to use the rest api to get the files.

Ok I have found in your fibaroExtra.lua all needed functions to play with QA Files 😀

I am working on a HomeTable creation and averything were OK, homeTable json was registered in my global variable as a string.

I am also able to display in an HTML table all items of the table(aR') constructed by the QA but when I am trying a tableString=json.encode(aR) I am getting this error:

HOMETABLE5555]: ...scoop\apps\python\current\Lib\site-packages\lua\init.lua:'utf-8' codec can't decode byte 0xc3 in position 3887: invalid continuation byte

I looked in the table aR and no special characters is included in (I did previously suppressed all special characters).

How I can diagnose where is the problem?

Byte 0xc3 together with the following byte in a string is used to signal utf-8 encoding of a character in a string.

Typically "foreign language" characters...

json.encode in plua don't have a problem with ute-8 if they are valid utf-8 codes.

In your case it sees 0xc3 but the byte following is not valid. 

 

You say that "homeTable json was registered in my global variable as a string."

-That means that you managed to encode the string?

You can try this function to find the string that don't want to be encoded:
