How do I know if the lua script is running? Script is located in domoticz\scripts\lua

In the log of domoticz?

Since I'm not a programmer is there someone willing to check, validate both scripts (wiki = switch device and this forum = text device). For now I have update the wiki page, but duplicates and inconsistencies in both scripts can be deleted I expect.

Good job, but you can also do it this all in 1 script..
Please look a couple messages back, its written as 1 script with 3 options:
Device on/off
Text device
Send notification

If you need help let me know

If all ok, you should see these lines in the log under status tab.

Hi BarryT, if you can help that is appreciated. Are you able to combine the suggested improvements in a single script then I will update the wiki. P.s. I also see that the rain.tmp file is updated each minute...

In this post 'zicht' suggest to not use a tmp file...
http://www.domoticz.com/forum/viewtopic ... 40#p128588
In this post it is mentioned not all 3 devices are working as expected.
http://www.domoticz.com/forum/viewtopic ... 60#p130239

So I'm a bit dazzled.

Can you put the script in the events under Domoticz and see if that will result a status log update?

ok...@BarryT, thanks for your help. Highly apreciated. The basic script is up and running! Now I am trying to add notification in the script and that doesnt work,........YET! Again. Thanks.

I use the following code in my rain code

Code: Select all

if (RainPrediction > 20  ) then
      verw = 3
      RainPredictionText=('('..round(RainmmHour, 1)..' mm) regen verwacht!')
      commandArray['SendNotification']='Regenscript#Regen verwacht'
      commandArray['Regenverwacht']='On'
   else 
      verw = 2
      RainPredictionText=('Voorlopig blijft het droog!')
   --commandArray['SendNotification']='Regenscript#Geen regen meer verwacht'
      commandArray['Regenverwacht']='Off'
   end

Tise part

Code: Select all

--commandArray['SendNotification']='Regenscript#Geen regen meer verwacht'

is disabled otherwise i get an message every minute when its not raining, but, when it IS raining i do get a message every minute, is it possible to change this is only once when it start to rain or when something changes?

Weird, I used both scripts as mentioned on the wiki page and don't have any issue.
http://www.domoticz.com/wiki/Is_it_gonna_rain

Did you make is a time driven script or is it a device change driven script?

Does anybody got suddenly the follow error as well:

I got this one again "Error: EventSystem: Warning!, lua script /home/pi/domoticz/scripts/lua/script_time_rain.lua has been running for more than 10 seconds"

As stated before: you really shouldn't be running this with the event system as it is single threaded making the even system unresponsive during the run of this script.
I have a variation of the script running in the background as a CRON scheduled task and is running fine for quite a while now.

Interesting... are you willing to share your script?

Of course: This is the script I have and it feed both a Rain and a percentage device. In case you don't want the percentage chance of rain device you need to remove the code at the bottom of the lua which tries to update that.
The filename and crontab task are listed in the source.
Just update the information in the top part and check if you want both devices to be fed with information.

So its better to have a script running outside Domoticz? I have also some scripts running inside Domoticz...

Hi All,

Moves the LUA script from inside Domoticz into the /scripts/lua/ location to see if some errors will stop. But there still there:

This is the script im using:

      if ((difference > 0) and (difference<=minutesinfuture*60)) then
         if debug then print('Line in time range found') end
         rain=tonumber(string.sub(tostring(line), 0, 3))
         totalrain = totalrain+rain

      end

   end

   averagerain=totalrain/rainlines
   return(averagerain)

return commandArray

My Internet connection is stable (VPN on mac is always on without disconnections) and speed is around 90-100Mbit/sec

Can someone help me or tell me why this error is still there?

I have the feeling that you didn't understood the instructions quite well.
This script shouldn't run like a so-called time or device script.
It is a script you fire from crontab at regular times. So to provide more help I would like to know the full path and name of the script. Make sure the script is disabled in the domoticz event screen. Ad the script to your crontab and fire it. Let's see what happens.

Clear answer. I will add it to crontab and see what happens
