http command

[Sagitarius]

As you can add multipple devices to a scene, would be great to have also the option to add multipple http commands

[Egregius]

Put them in a script and execute that script.

Hi All,
I'm trying to get PV information from Benning device via dzvents into domoticz.
The IE http command like "http://<IP PV>/getentry.cgi?&oid=10" works fine.
Result e.g.
[
{
"oid" : 10,
"label" : "UserConfig.Inverter.Info.SystemName", "type" : "S",
"val" : "PVINV110",
"uitext" : "System name", "savetype" : 1,
"factor" : 1.000000, "unit" : "", "portal" : 1,
"AutoZero" : 0,
"fb" : 1
},

but to be honest, I have no clue how the dzvents "openURL" command should look like

Anyone out there to help ?

Many thanks
Rgds

Hi Rob,
thanks, I had a view on this but the 2nd part, looks like, is a bit complex for me yet.
That's what I have so far

Code: Select all

return {
    on = {
    timer = {'every 1 minutes'},
    httpResponses = { 'oid' }
    },

    execute = function(dz, item)
        
    if (item.isTimer) then  
	    dz.openURL({
	    url =  'http://192.168.178.20/getentry.cgi?&oid=10',
	    method = 'GET',
	    callback = 'oid',
	    })
	end

    if (item.isHTTPResponse) then
        if (item.ok) then
            local pv_data = dz.utils.toJSON(item.data)
          	dz.log('PVSW30 ' .. pv_data, dz.LOG_ERROR)
        else
            dz.log('PVSW30 not OK', dz.LOG_ERROR)
        end
    end

    end
}

Can you try this one? It is not complete but should point you in the right direction

Code: Select all

local scriptVar = 'oid'

return
{
    on =
    {
        timer =
        {
            'every 1 minutes'
        },
        httpResponses =
        {
            scriptVar,
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },

    execute = function(dz, item)

        if item.isTimer then
            dz.openURL(
            {
                url =  'http://192.168.178.20/getentry.cgi?&oid=10',
                method = 'GET',
                callback = scriptVar,
            })
        elseif item.isHTTPResponse and item.ok then
            dz.log('item.data: ' .. item.data, dz.LOG_FORCE)

            dz.utils.dumpTable(item) -- only during debug

            local pv_data = dz.utils.fromJSON(item.data) -- you want to convert a JSON to a Lua table
            dz.utils.dumpTable(pv_data) -- only during debug
        else
            dz.log('PVSW30 not OK', dz.LOG_ERROR)
        end

    end
}

Thanks Waaren, will spend some time over the weekend

Hi Waaren

that's what I get, but I'm not sure what kind of information would help.
The http command via IE works fine. It collects data from a XML database where I do not have the name from.
But anything I tried so far, the result via openURL would be -1, which means wrong oid no. and the JSON object
is not shown.

I could not find a hint in regards to bad argument .......

[waaren]

that's what I get, but I'm not sure what kind of information would help.

The call only returns -1 so not much to work with. It should return the same information as what comes back if you enter this http in your browser. Can you try to do this from an incognito browser page and post the result?

[Sagitarius]

I tested Chrome and Firefox in private mode, Firefox has no problem but Chrome
has problem with oid's below 10000, they are not working but above some.
I did the same test with Domoticz and got the same result like with Chrome.
