Help needed get Data from Weatherstation Lua to dzvents

Fine Offset weatherstation

Hi, I tried to change a lua script, to fetch data from my personal weatherstation, into dzvents.
Lua works
Spoiler: show

Code: Select all

commandArray = {}
time = os.date("*t")
    if  ((time.min % 10)==0)  then
        
os.execute('sudo wget http://192.xxx.xxx.xx/weewx_pws.xml -O /path to/weewx_pws.xml')

local filename = "path to/weewx_pws.xml"

local line = ''
local temperature = 0
local tempdevice = ''

for line in io.lines(filename) do
   if string.find(line,"\"temp\"") then
      temperature=tonumber(string.match(line, "%-?%d+.?%d*"))
  end
end

-- Update virtual device idx
tempdevice='idx|1|'..temperature..';0'

--print(tempdevice))

commandArray['UpdateDevice'] = tempdevice
end
return commandArray
dzvents need help

Code: Select all

return {
	on = {
	    timer = {'every 1 minutes'}
	    --,devices = {'triggerhulp'}
	},
	    execute = function(domoticz)
        -- check time of the day
        if domoticz.time.isDayTime then

         os.execute('sudo wget http://xxx.xxx.xxx.xx/weewx_pws.xml -O /path to/weewx_pws.xml')
            local filename = "/path to/weewx_pws.xml"
            local line = ''
            local temperature = 0
            local tempdevice = ''
            for line in io.lines(filename) do
            if string.find(line,"\"temp\"") then
            temperature=tonumber(string.match(line, "%-?%d+.?%d*"))
      end
  end    
--Update virtual device id , nval(0) sval (temp)
--tempdevice='208|1|'..temperature..';0'

--print(tempdevice))

tempdevice = domoticz.devices('WetterAußen') 
    end
end
}

till os.execute('sudo wget http://xxx.xxx.xxx.xx/weewx_pws.xml -O /path to/weewx_pws.xml') It's running.
I don't know how to get data from xml file and update my Temperature sensor.
THX for any help

This script will get the data from the weatherstation. If you can execute it once and share the loglines I can continue from there.
Also please state what version of domoticz / dzVents you use.

Code: Select all

local url = 'http://xxx.xxx.xxx.xxx/weewx_pws.xml'
local scriptVar = 'getXML' 

return 
{
    on = 
    {
        timer = 
        {
            'every minute at daytime',
        },
        
        devices = 
        {
            'triggerhulp',
        },
    
        httpResponses =
        {
            scriptVar,
        },
    },

    logging = 
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },
    
    execute = function(dz, item)

        if item.isHTTPResponse then
            if item.ok then
                dz.log(item,dz.LOG_DEBUG)
            else
                dz.log('There was a problem handling the request', dz.LOG_ERROR)
                dz.log(item, dz.LOG_ERROR)
            end
            return

            -- tempdevice = domoticz.devices('WetterAußen') 
        end

        dz.openURL(
        {
            url = url, 
            method = 'GET',
            callback = scriptVar,
        })
    end
}

Thanks for your quick reply!
I use newest domoticz beta 11.796 and dzvents 3.0.1.
I will check the script in a couple of minutes!

Next step:

converting the XML to a table.
Please execute this one and show the result + tell what value needs to go to what device (name or id and type/ subtype)

Code: Select all

local url = 'http://xxx.xxx.xxx.xxx/weewx_pws.xml'
local scriptVar = 'getXML' 

return 
{
    on = 
    {
        timer = 
        {
            'every minute at daytime',
        },
        
        devices = 
        {
            'triggerhulp',
        },
    
        httpResponses =
        {
            scriptVar,
        },
    },

    logging = 
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },
    
    execute = function(dz, item)

        if item.isHTTPResponse then
            if item.ok then
                --dz.log(item,dz.LOG_DEBUG)
                rt = dz.utils.fromXML(item.data)
                dz.utils.dumpTable(rt)
            else
                dz.log('There was a problem handling the request', dz.LOG_ERROR)
                dz.log(item, dz.LOG_ERROR)
            end
            return

            -- tempdevice = domoticz.devices('WetterAußen') 
        end

        dz.openURL(
        {
            url = url, 
            method = 'GET',
            callback = scriptVar,
        })
    end

The log file location is set in /etc/init.d/domoticz.sh in the
DAEMON_ARGS section.
I have these but you ports, location of logfile, etc could vary

Code: Select all

DAEMON_ARGS="-daemon"
DAEMON_ARGS="$DAEMON_ARGS -daemonname $NAME -pidfile $PIDFILE"
DAEMON_ARGS="$DAEMON_ARGS -www 8084"
DAEMON_ARGS="$DAEMON_ARGS -sslwww 8443"
DAEMON_ARGS="$DAEMON_ARGS -log /var/log/domoticz.log"    # location of logfile 
DAEMON_ARGS="$DAEMON_ARGS -loglevel  normal,status,error"
if you change something in this file you need a

Code: Select all

sudo systemctl daemon-reload
sudo domoticz stop
sudo domoticz start

Thank you very much! Your code is working, I already modified your script to get more sensors. I have trouble to get just windgust, I want to use the gust to control my blinds.

Code: Select all

local gust = dz.devices('Gust')                     --devicetype utility
gust.updateGust(data.windGust)

The get part is already OK but updateGust() is not a known dzVents method. (see the wiki )
How does the complete row of your device 'Gust' look like in the devices tab ?

Got it because it is a custom sensor
gust.updateCustomSensor(data.windGust)

Thank you very much!
One more question. What is 'triggerhulp' for?

triggerhulp is a device I use for testing the script. I don't like to wait during development until the next full minute :D So I use a virtual switch to trigger the script immediately after I corrected a typo or a bug. When the script is ready and tested you can remove that part.

Is it possible to get a time stamp for the xml file? Sometimes my weatherstation lost the USB connection to my Rpi. In that case the domoticz script got old data but doesn't remark it. So I have the same datas on my dummy devices for hours:(
I know this code want work but it's just to show what I'm talking about.

If timestamp 5 times equal then
ssh reboot my weatherpi

Yes, in below example I use station_time for that
You will have to change the ssh bootcommand in line 115 as I don't know what command you need for that.

Hello waaren, thx again for your help.
in this line
if dz.data.stationTime == rt.station_time then dz.data.equalCounter = dz.data.equalCounter + 1

I got an error
2020-03-25 18:25:01.209 Error: dzVents: Error: (3.0.1) getXML: ...ticz/scripts/dzVents/generated_scripts/Wetterstation.lua:100: attempt to index a nil value (field 'data')

Are you sure you copied / paste all new lines ?

I suspect that you missed the data part between logging = and execute =

I try to understand the code and have some questions and remarks. I put them into your code. The error occur in the second line.

Code: Select all

local rt = getData(item.data) --local rt should find and get all datas in xml? Why 
                if dz.data.stationTime == rt.station_time then dz.data.equalCounter = dz.data.equalCounter + 1 
                    --compare the two times if false then counter +1. 
                    --Where is dz.data.stationTime from? I assume rt.station_time should be station_time from xml? 
                    --rt.station_time because of line before?

No the other way around. When equal increase counter
All times are UTC+01:00
