This script will get the data from the weatherstation. If you can execute it once and share the loglines I can continue from there.
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
}
Next step:
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
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"
Code: Select all
sudo systemctl daemon-reload
sudo domoticz stop
sudo domoticz start
Script could look like this. Just comment the devices and updatelines you don't use.

triggerhulp is a device I use for testing the script. I don't like to wait during development until the next full minute
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. Yes, in below example I use station_time for that

attempt to index a nil value (field 'data') Are you sure you copied / paste all new lines ?
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?
You are right. Know it's working! THX again for your help! --compare the two times if false then counter +1.
