How to set a QA variable from a LUA scene ?

[jguellec 14]

Hi there ?

 

I’m looking for a way to populate QuickApp variable from a LUA scene. 

 

I know I can GET variables by querying the API :

but can we also populate them ?

 

Have a good day !

how would i check if the variable exits?

function getVariable(deviceID,name)

    for _,v  in ipairs(api.get("/devices/"..deviceID).properties.quickAppVariables) do

        if v.name==varName then return v.value end

    end

end

and then if the result is nil does that mean the variable does not exist?

 

also running this seems to loop for ever

function setVariable(deviceId,name,value)

    local vs = api.get("/devices/"..deviceId.."/properties/quickAppVariables")["value"]

    --local vs = api.get("/devices/"..deviceId.."/properties/quickAppVariables").value

    for _,v in ipairs(vs) do

        if v.name==name then -- existing

            v.value = value 

            return api.put("/devices/"..deviceId,{properties={quickAppVariables=vs}})

        end

    end

    vs[#vs+1]={name=name,value=value} -- new

    api.put("/devices/"..deviceId,{properties={quickAppVariables=vs}})

end
