Set Level (variable number)

[JonyBCN]

I am starting with LUA. I am a Siemens PLC programmer, I work with a graphical interface and I do not program code, so maybe things that I take for granted are not, apologize in advance.

I am automating an awning, and I have doubts with the command (commandArray ['Device'] = 'Set Level NN').
Submitting the level works, but I'd like to give the system a twist. It is possible to do something like (commandArray ['Awning'] = 'Set Level (VARIABLE))'.
My idea is that if a strong wind gust blows, save the current level in a variable and close the awning, and when the wind gust stops, return the awning to the original position.

Yes, that should be possible. Something with tonumber(variable) and concatenate 2 strings. I can not give an example right now, but google to lua syntax should help.

If you save it in a uservariable, it should be possible.

Well, to give you an idea of how I "program" in my work I paste this image:



So starting with LUA for me is a totally new concept and I have to get used to it.
I will try to find out more about the subject, although any help is welcome.

What is the device type / subtype of your awning device in domoticz as seen on the device tab and how does it look on the switch tab?

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents enabled' is checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

if it is a selector type this could work.

Code: Select all

return
{
    on =
    {
        devices =
        {
            'myWindDevice', -- change to name of your wind sensor device
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- change to domoticz.LOG_ERROR when all is OK
        marker = 'storeSelector',
    },

    data =
    {
        previousLevel =
        {
            initial = -1,
        },
    },

    execute = function(dz, item)
        local maxGust = 20
        local awning = dz.devices('myAwning') -- change to name of your awning

        if item.gust > maxGust and awning.levelName ~= 'Off' then
            awning.switchSelector('Off')
            dz.data.previousLevel = awning.level
        elseif item.gust < maxGust and dz.data.previousLevel ~= -1 and awning.levelName == 'Off' and awning.lastUpdate.secondsAgo > 900 then
            awning.switchSelector(dz.data.previousLevel)
            dz.data.previousLevel = -1
        end

    end
}

if it is a dimmer type you could try

Code: Select all

return
{
    on =
    {
        devices =
        {
            'myWindDevice', -- change to name of your wind sensor device
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- change to domoticz.LOG_ERROR when all is OK
        marker = 'storeSelector',
    },

    data =
    {
        previousLevel =
        {
            initial = -1,
        },
    },

    execute = function(dz, item)
        local maxGust = 20
        local awning = dz.devices('myAwning') -- change to name of your awning

        if item.gust > maxGust and awning.state ~= 'Off' then
            awning.dimTo(0)
            dz.data.previousLevel = awning.level
        elseif item.gust < maxGust and dz.data.previousLevel ~= -1 and awning.state == 'Off' and awning.lastUpdate.secondsAgo > 900 then
            awning.dimTo(dz.data.previousLevel)
            dz.data.previousLevel = -1
        end

    end
}

Thank you very much for the help.

I have been doing tests (the awning is a level, Domoticz treats it as a blind) and it works, although I have had to change this: "dz.data.previousLevel = (awning.level)".

Thank you for pointing me in the correct address. Now I want to continue investigating to give it more functions.
