Access to Global Tables (ie. otherdevice_svalue) in LUA_Parsers scripts.

[boe666]

It is very important and usefull function. It was in oldest version and I don't know why now is not.

Could you check the result of this dzVents script ?
Is this the Global Table you want ? If not can you please elaborate a bit more on what exactly you are looking for ?

--[[ Global table

return {
    on =        {   timer = { 'every minute' }  },
      
    logging =   {   level   = domoticz.LOG_DEBUG, 
                    marker = "Global table"},  

    execute = function(dz, trigger)
    
        local seen = {}
        function dumpTable(t,i)
            seen[t] = true
            local s= {}
            local n=0
            for k in pairs(t) do
                n=n+1 s[n]=k
            end
           table.sort(s)
            for k,v in ipairs(s) do
                dz.log(i .. ">" .. v,dz.LOG_DEBUG)
                v=t[v]
                if tostring(type(v))=="table" and not seen[v] then
                    dumpTable(v,i .. ".")
                end
            end
        end

        dumpTable(_G,"")
    
    end
}

I'm sorry but I don't use dzVent script.
My problem is:
1. My harware invoke scripts (http) like: <domoticz_IP>/json.htm?type=command&param=udevices&script=d10.lua&s=1, with 5s interval.
2. Domoticz use d10.lua file (from LUA_parsers directory) to execute script (to read variable s as 1 and save to domoticz by domoticz_updateDevice procedure)
but before domoticz_updateDevice, script checked actual state of sensors and make domoticz_updateDevice only when the state was different.
Now, global tables like otherdevice_svalue are empty. The examples from wiki (LUA Parsers examples) not working too.

DzVent can catch the domoticz_updateDevice procedure and check the actual status before make changes in domoticz databases ?

@boe666
my approach would be to change the json to send the your sensor data to User variable in Domoticz (User variables do not store history in database)

Code: Select all

http://192.xxx.xxx.xxx:yyyy/json.htm?type=command&param=updateuservariable&vname=tempParse&vtype=2&vvalue=12.65

and trigger dzVents script on User variable changed to check current value and update only when different.

--[[ 
parseTemp.lua

return {
    on      =   {   variables   = { "tempParse } },

    logging =   {   level       = domoticz.LOG_DEBUG,                   -- LOG_DEBUG, LOG_INFO or LOG_ERROR
                    marker      = "parseTemp" },

    execute = function(dz, trigger)
        local myTempDevice = dz.devices("your temperature devicename")          
        if dz.utils.round(myTempDevice.temperature,2)  ~= dz.utils.round(trigger.value,2) then
            myTempDevice.updateTemperature(trigger.value)
            dz.log("Device " .. myTempDevice.name .. " updated. New temperature is " .. trigger.value .. "°C. Old temperature was " .. myTempDevice.temperature .. "°C." ,dz.LOG_DEBUG)
        else
            dz.log("Device " .. myTempDevice.name .. " does not need an update. Temperature is " .. dz.utils.round(trigger.value,2) .. "°C" ,dz.LOG_DEBUG)
        end    
    end
}

how i can define uservariables ?
Where can I find some examples of this dzVent triggers ?

If you press the show button after the word spoiler in my previous post you will see a dzVents script that will execute every time the user variable is updated.
You can read everything needed on dzVents in the wiki

For uservariables please have a look here

[boe666]

I write some code in my script:
commandArray = {}
print ("Write to test1");
local alarm_ruch = uri['a'];
print ("Variable val:");print(alarm_ruch);
commandArray['Variable:test1'] = tostring(alarm_ruch);
print ("End Writing");

but value of my variable (defined in domoticz in uservariable section) has no change.
i think lua_parsers script has no access to commandArray table.....
How can I send this value to the uservariable with json method ?

I use json.htm?type=command&param=udevices&script=d10.lua&s=1&a=5&f=5... because i can send many variables in one pass, and my harware (http gateway) has limit of char in url (255 chars).

[boe666]

Any body know WHY access to global tables and global variables is disables in LUA_Parsers script ????

[boe666]

OK, it was my mistake.... I'm sorry for my indolence...
my scripts has no access to global tables becouse i don't turn on this function....
