I would like to send my Omnik data "Countertoday" and "Usage" with MQTT publish to my openWB (Charging station), but I am not very familiar with Dzvents. Please help.

This need openWb

Per MQTT zu schreiben:
openWB/set/pv/1/W PV-Leistung in Watt, int, negativ
openWB/set/pv/1/WhCounter Erzeugte Energie in Wh, float, nur positiv

Output Omnik/PVoutput

Spoiler: show

What is the type / subtype of this device as seen on the devices tab?
What is your domoticz version?
Can the domoticz user execute the mosquitto client mosquitto_pub?

Could look like below

Code: Select all

local scriptVar = 'solar2omnik'
return
{
    on =
    {
        devices =
        {
            'Zonne Panelen',
        },
        shellCommandResponses =
        {
            scriptVar,
        }
    },

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

    execute = function(dz, item)

        if item.isDevice then
            local MQTTBase = "mosquitto_pub " -- or full qualified program name

            local omnikLeistung  = MQTTBase ..' -m ' .. (item.actualWatt * -1) .. ' -t openWB/set/pv/1/W '
            local omnikErzeugt = MQTTBase .. ' -m  '.. item.WhTotal ..  ' -t openWB/set/pv/1/WhCounter '

            dz.executeShellCommand(
            {
                command = omnikLeistung .. '; ' .. omnikErzeugt,
                callback = scriptVar,
                timeout = 10,
            })
        elseif item.isShellCommandResponse then
            if item.statusCode == 0 then
                dz.log('commands processed OK',dz.LOG_DEBUG)
            else
                dz.log('commands processed NOK',dz.LOG_ERROR)
                dz.log(item,dz.LOG_DEBUG)
            end
        end
    end
}

Thanks i test it soon.

After changing line 27 I get the correct value in "openWB"
local omnikLeistung = MQTTBase ..' -m ' .. math.floor(item.actualWatt + 0.5) .. ' -t openWB/set/pv/1/W '

Line 28 indicates in "openWB" the total yield "Data" and not the daily yield "CounterToday"

Thank you very much for now.

So I guess changing line 28 from

Code: Select all

local omnikErzeugt = MQTTBase .. ' -m  '.. item.WhTotal ..  ' -t openWB/set/pv/1/WhCounter '

to

Code: Select all

local omnikErzeugt = MQTTBase .. ' -m  '.. item.counterToday ..  ' -t openWB/set/pv/1/WhCounter '

should fix that ?

That's the solution, thank you again.
