multiply kWh value

Post by jacobsentertainment »

Hi all,

I got an script running for my heating system and the amount of energy that i put in is determined by the value of the kWh that is available of the solar panels. I would like to add something to the script to increase this value by a percentage
Full script in use (works fine)

return {
on = {
devices = {
260
},
},

logging = {
level = domoticz.LOG_INFO,
marker = "Boiler verwarming"
},
execute = function(domoticz, devices)
local Inverter = domoticz.devices(260)
local Kwh = Inverter.actualWatt
local Boiler_tempT = domoticz.devices(250) -- gem temp boiler totaal
local Temp_BT = Boiler_tempT.temperature

}
My plan is to have some simple number in the script to multply the value of the Kwh, but I tried this and this doesn't work.

Code: Select all

            local Inverter = domoticz.devices(260)
                local Kwh = Inverter.actualWatt + 30%
How can I get this to work?

To add 30 percent I usually multiply with 1.3

Code: Select all

local Inverter = domoticz.devices(260)
local Kwh = Inverter.actualWatt*1.3

Now I'm trying to have this in a other setup, as soon as I have full power of the panels I dont need to add power of the grid, so when its below a value I want to add some power of the grid etc. But this won't work ;) Any suggestion here :mrgreen:

Code: Select all

return {
        on = {
          devices = {
            260
        },
    },
    
    	logging = {
        level = domoticz.LOG_INFO,
        marker = "Boiler verwarming"
    },
        execute = function(domoticz, devices)
       local Inverter = domoticz.devices(260)
            local Kwh = Inverter.actualWatt

        
        if Kwh >= 10 and Kwh <= 4000 then 
            domoticz.devices(275).updateEnergy((actualWatt)*1.5)
        elseif
            Kwh >= 4000 and Kwh <= 6000 then 
                domoticz.devices(275).updateEnergy((actualWatt)*1.3)
                elseif
                    Kwh >= 6000 then 
                        domoticz.devices(275).updateEnergy(actualWatt)
                        
        end
end
}

add some logging to show what Kwh is.

This is data coming from the growatt inverter.

(some background info)
I use this to power my heating system. So at this moment I use all the power of the panels rounded down for heating, but the temperature is dropping and the sun power to so I want to add some power of the grid because that's cheaper then gas. So but when the panels are giving full output I don't want to add power of the grid, only in the lower power zone (so to say) so if the power from the panels is between 0 and 4kW add 50% and is its between 4kW and 6kW add 30% and above nothing.
So instead of changing any on the growatt plugin I just make a new dummy thats updated with above values and from there the power is regulated.
