Hello,

I need some help in diagnosing a script.

In my setup when a pump is turned on, waterflow readings are being sent to Domoticz every second. They are fed to a waterflow sensor and a variable (as I could not get dzVents or Blockly to work with the sensor). I need a script to check the waterflow around 20 seconds after the pump was started. If it's too low, a safety switch should be triggered. My script looks like this:

Code: Select all

return {

	on = {	variables = {"pompa_zbiornika_przeplyw"},
	   
	data = { count = { initial = 0 }
	   
	    },
 
 
   execute = function(domoticz, _)
	    
       local przeplyw = domoticz.variables("pompa_zbiornika_przeplyw").value
       local pompa = domoticz.devices("POMPA ZBIORNIKA").state

       if (pompa == "On")  then
       
           domoticz.data.count = domoticz.data.count + 1
        
       
       elseif (pompa ~= "On") then
       
           domoticz.data.count = 0 
         
       end     
        
       if  (domoticz.data.count >= 20 ) then 
        
           if (przeplyw >= 0 and przeplyw <= 5 and pompa == 'On' ) then 
	
	      domoticz.devices("BLOKADA POMPY ZBIORNIKA").switchOn().checkFirst()
              domoticz.data.count = 0 
              
           elseif (przeplyw > 5 and przeplyw < 22 and  pompa == 'On' ) then 
		 
	      domoticz.devices("BRUDNY FILTR ZBIORNIKA").switchOn().checkFirst()
	      domoticz.data.count = 0 
	      
          end
        end
     end  
}
}

It doesn't report any errors, however it's never triggered. I get constant info on the log that the variable was updated, however the script does not run. Updating the waterflow variable manually also does not trigger the script.

You made a small mistake misplacing one of the }

To prevent such easy made mistakes you could use an approach where you align all opening and closing ones at the same column.

Code: Select all

return 
{
    on = 
    {    
        variables = 
        {
            "pompa_zbiornika_przeplyw",
        },
    },
    
    data = 
    { 
        count = 
        { 
            initial = 0, 
        },
    },
     
     logging = 
    {
        level = domoticz.LOG_DEBUG,
        marker = 'waterflow',
    },
 
   execute = function(domoticz)
        
       local przeplyw = domoticz.variables("pompa_zbiornika_przeplyw").value
       local pompa = domoticz.devices("POMPA ZBIORNIKA").state

       if pompa == "On"  then
           domoticz.data.count = domoticz.data.count + 1
       else
           domoticz.data.count = 0 
       end     
        
        if  (domoticz.data.count >= 20 ) then 
            if (przeplyw >= 0 and przeplyw <= 5 and pompa == 'On' ) then 
                domoticz.devices("BLOKADA POMPY ZBIORNIKA").switchOn().checkFirst()
                domoticz.data.count = 0 
            elseif (przeplyw > 5 and przeplyw < 22 and  pompa == 'On' ) then 
                domoticz.devices("BRUDNY FILTR ZBIORNIKA").switchOn().checkFirst()
                domoticz.data.count = 0 
            end
        end
     end  
}
