I have a 4 dummy device "temperature"

local idx = 52 -- TN2
local idx = 53 -- TW2
local idx = 54 -- TN1
local idx = 55 -- TW1
local idx = 60 -- ETV ( Efficiency Temp of Ventilation)

And I have simple equation:
ETV = (TN2 -TN1) / (TW1 - TW2) *100%

And the result I need post in the IDX 60.

return  {
    
    on          =   {   devices         =   { 52,53,54,55 }}, 
                    
    logging     =   {   
                        level           =   domoticz.LOG_DEBUG,
                        marker          =   "Ventilator efficiency"     
                    },

    execute = function(dz,item)
        local function logWrite(str,level)
            dz.log(tostring(str),level or dz.LOG_DEBUG)
        end
    	   

        local TN2 = dz.devices(52).temperature -- TN2 
        local TW2 = dz.devices(53).temperature -- TW2 
        local TN1 = dz.devices(54).temperature -- TN1 
        local TW1 = dz.devices(55).temperature -- TW1
        local ETV = dz.devices(60)              -- ETV ( Efficiency Temp of Ventilation)
        -- And I have simple equation:
        local result = dz.utils.round(((TN2 -TN1) / (TW1 - TW2) * 100),2)
        
        -- And the result I need post in the IDX 60.
        ETV.updatePercentage(result)
        logWrite ("Calculated ETV: " .. result)  
        
    end
}

Assuming device 60 is of type percentage this dzVents script could be a solution.

Code: Select all

return  {
    
    on          =   {   devices         =   { 52,53,54,55 }},

                        level           =   domoticz.LOG_DEBUG,
                        marker          =   "Ventilator efficiency"     
                    },

    execute = function(dz,item)
        local function logWrite(str,level)
            dz.log(tostring(str),level or dz.LOG_DEBUG)
        end
    	   

        local TN2 = dz.devices(52).temperature -- TN2 
        local TW2 = dz.devices(53).temperature -- TW2 
        local TN1 = dz.devices(54).temperature -- TN1 
        local TW1 = dz.devices(55).temperature -- TW1
        local ETV = dz.devices(60)              -- ETV ( Efficiency Temp of Ventilation)
        -- And I have simple equation:
        local result = dz.utils.round(((TN2 -TN1) / (TW1 - TW2) * 100),2)
        
        -- And the result I need post in the IDX 60.
        ETV.updatePercentage(result)
        logWrite ("Calculated ETV: " .. result)  
        
    end
