From Windy to Domoticz [Solved]

[javalin]

Good Morning,

I am trying to create code to get data from 2 Windy wind stations to send it to 2 domoticz dummy wind devices in the same script. If I create 1 script independently for each WS there is no problem, it works. But with a single script I am not managing to update the last dummy wind device.

This is my code:

Code: Select all

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

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'WindyStation',
    },

    execute = function(dz, item)
        local dznumber = 0
        local urlData = 0
        local count = 0
        local controls = -- control table
        {
            {
                Rota = true,         -- conditions
                post ='https://node.windy.com/obs/measurement/v2/ad-LERT/7/1?',
                device = 644
            },
            {
                Faro = true, 
                post = 'https://node.windy.com/obs/measurement/v2/ad-LPFR/7/1?',
                device = 645
            },
        }

        local function post(getData)
            dz.openURL(
            {
                url = urlData,
                method = 'GET',
                callback = scriptVar, -- httpResponses above.

At the moment the script send data to the first dummy wind device (idx=644). Problem is how send data to the second dummy wind device.

Can you try this one?

Thank you waaren, it works.

Code: Select all

local function windDirection( nDir )
windDirections = { 'N', 'NNE','NE','ENE','E','ESE','SE','SSE','S','SSW','SW','WSW','W','WNW','NW','NNW' , 'N'}
return ( windDirections[ math.floor(  ( nDir + 11.25 ) / 22.50 ) + 1 ] )
end

The beatiful way to get the cardinal point, I would never have thought of dividing the compass rose into 16 parts to extract the cardinal point. Simply brilliant

Code: Select all

local idxStr = item.trigger:gsub(scriptVar ..'_', '')

So idx device is part of the Callback and this is the solution to store the 'idx device' when script is executed by the httpResponse?

Code: Select all

local winddir = item.json.data.windDir[#item.json.data.windDir]

For some strange reason and only in one of the wind stations #item.json.data.windDir does not get the total number of recordings, I have taken a look to the json windDir table and it has several null records, this may be the reason. Temperature, wind and windDir json tables have the same number of records so I have changed the line to:

Code: Select all

local winddir = item.json.data.windDir[#item.json.data.temp]

and fixed the issue.

[AllesVanZelf]

Hello Javalin,
This is wonderfull! Did you create a virtual text sensor for this? The idx'es?
Where did you find the hyperlink to this locations?

Edit: Yes already found it. I choose dummy type wind+temp+'gevoel'. And on the website choose a location and nearest weatherstations.
Thank you!

[waaren]

Code: Select all

local idxStr = item.trigger:gsub(scriptVar ..'_', '')

So idx device is part of the Callback and this is the solution to store the 'idx device' when script is executed by the httpResponse?

Yes. Attached to callback when send and extracted when callback returns

Code: Select all

local winddir = item.json.data.windDir[#item.json.data.windDir]

For some strange reason and only in one of the wind stations #item.json.data.windDir does not get the total number of recordings, I have taken a look to the json windDir table and it has several null records, this may be the reason. Temperature, wind and windDir json tables have the same number of records so I have changed the line to:

Code: Select all

local winddir = item.json.data.windDir[#item.json.data.temp]

and fixed the issue.

Is indeed caused by the null values which are translated by the JSON handler to nil, and thus making gaps in the array.
See below for a solution using the lodash library for Lua. This will do the job in a more robust way using the _.findlast method.

Code: Select all

local scriptVar = 'WindyStation'
return

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

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = 'WindyStation',
    },

    execute = function(dz, item)

        local _ = dz.utils._   -- lodash library for Lua

       local controls = -- control table
        {
            {
                Rota = true,         -- conditions
                post ='https://node.windy.com/obs/measurement/v2/ad-LERT/7/1?',
                device = 644,
            },
            {
                Faro = true,
                post = 'https://node.windy.com/obs/measurement/v2/ad-LPFR/7/1?',
                device = 645,
            },
        }

        local function post(url, id)
            dz.openURL(
            {
                url = url,
                callback = scriptVar .. '_' .. id, -- attach _id to the callback string
            })
        end

        local function walkConditions(type)
            for key, value in ipairs(controls) do
                if value[type] then
                    post(value.post, value.device)
                end
            end
        end

        local function windDirection( nDir )
            windDirections = { 'N', 'NNE','NE','ENE','E','ESE','SE','SSE','S','SSW','SW','WSW','W','WNW','NW','NNW' , 'N'}
            return ( windDirections[ math.floor(  ( nDir + 11.25 ) / 22.50 ) + 1 ] )
        end

        if item.isTimer then
            walkConditions('Rota')
            walkConditions('Faro')

        elseif item.json then
            local idxStr = item.trigger:gsub(scriptVar ..'_', '') -- extract idz from callback string
            local idx = tonumber(idxStr) -- must be numeric
            dz.log('Values for device ' .. idx ,dz.LOG_DEBUG )

            local temperature = _.findLast(item.json.data.temp) - 273.15 -- _.findLast function does return the last element of the array. See
            local windspeed = _.findLast(item.json.data.wind) -- https://htmlpreview.github.io/?https://github.com/rwaaren/lodash.lua/blob/master/doc/index.html#_.findLast
            local winddir = _.findLast(item.json.data.windDir)

            dz.devices(idx).updateWind(winddir, windDirection(winddir),windspeed,0,temperature,0)

            dz.log('temperature: '..temperature ..' ºC' , dz.LOG_DEBUG )
            dz.log('wind: '..windspeed * 1.94 ..' knots' , dz.LOG_DEBUG)
            dz.log('winddir: '..winddir ..' º' , dz.LOG_DEBUG)
            dz.log('winddir: '..windDirection(winddir) , dz.LOG_DEBUG)

        else
            dz.log('problem with return', dz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
        end
end
}

This will do the job in a more robust way using the _.findlast method.

Thank you waaren, now it works even better. With the use of #tablename dummy wind device did not update when the wind speed or wind direction value was null. Now, with _.findlast method the wind device can update also to zero values.

[AllesVanZelf]

@Waaren and @javalin,
Is it possible to implement windgust?
It was mentioned in the first version and commented out.
And 'Wind chill' (/ gevoelstemperatuur)

[waaren]

Is it possible to implement windgust and 'Wind chill'

I guess so.
Can you give me the url where the windgust is part of the return so I can test? The Wind Chill is something I can calculate based on temperature and windspeed.

[AllesVanZelf]

If I see this page: link to station schiphol, I find:

Code: Select all

gust	
0	null
..
11	null
12	10.8 

Thank you, that would be great.

Thanks again Waaren. This is working well!!!

[AllesVanZelf]

Hmm. It was working for a while, but now Temp is zero.
I have this error in the Log:

Code: Select all

Error: dzVents: Error: (3.1.5) WindyStation: ...scripts/dzVents/generated_scripts/Windy all Schiphol.lua:77: attempt to perform arithmetic on a nil value 

Temperature is not updated and this gives an error in calculation?

Probably a data problem. Will build some extra protection around it.
The error you posted mention line 77 but in the script I posted, line 77 only contains

Code: Select all

end 

So I assume you added or removed some lines. If you do that and post an error with a line number, please also post the complete modified script. That will help in identifying the issue

OK. I updated the version (with some protection) in my earlier post.

@Waaren and @javalin,
Is it possible to implement windgust? 

I had disable Wind Gust line because, before upgrade script with _.findlast method, the script 'froze' when got a nil value. Faro and Rota has not Wind Gust values but others stations may.

I have discovered that original source that Windy shows came from METAR.

https://www.aviationweather.gov/metar

So, other way to get json info is in link bellow:

https://www.aviationweather.gov/cgi-bin ... 6639315631

Wind info is in rawOb line: "GMME 111330Z 35008KT 310V010 8000 NSC 19/13 Q1025 NOSIG"

[waaren]

I had disable Wind Gust line because, before upgrade script with _.findlast method, the script 'froze' when got a nil value. Faro and Rota has not Wind Gust values but others stations may.

I understand and that's why I added the "or 0" to windgust. So if _.findLast returns nil, the script will not crash but will replace nil with 0. This will give the same result as the hardcoded 0 in the updateWind statement you used.

[AllesVanZelf]

Thank you Waaren for all the effort you put into this!

Understood, thank you very much for the help waaren.

Today was the first day that I truly understood this message:

Sometimes, I don't understand what I read, no matter how much I repeat...
