Energy in dummy device in LUA

[journeyman]

Hello,

I have working Energy usage device (Dummy based on Pulse and ESP Easy).
In my home system I would like to se in IMperiHOME my daily usage. So the shortest way is to create another device

How in LUA can I take Daily usage from my first counter and put it to second "Daily" one?

Hello,

I made something similar but with two tarif.
Sorry, it's in french :

Unfortunately, completely I do not understand French but that is exactly what I need. Only if it will work with pulse counter from ESPEasy?

I would like to have insight into total consumption, monthly, daily, along with the enumeration of costs - divided into two fares. Tariff change me quite often.

I try to use your script, I put my ID devices. but I get an error

Code: Select all

 2017-03-07 11:09:00.279 Error: EventSystem: in Elektrownia: [string "function log(p_message)..."]:21: bad argument #1 to 'pairs' (table expected, got nil)
2017-03-07 11:09:12.790 Error: EventSystem: in Elektrownia: [string "function log(p_message)..."]:29: attempt to perform arithmetic on global 'EnergyImportLow' (a nil value)

Hello,

OK I think it is because your "idxCompteurIntelligent" is new and it has now initial value, so it return a nil value.
For the first time, the new CompteurIntelligent need to be initialize.
Can you add these lines before : EnergyImport = EnergyImportLow + EnergyImportHigh

-- For the first time, the value are not initilize in the smart counter, we set 0 by default.
if(EnergyImportLow == nil)then
EnergyImportLow =0
EnergyImportHigh =0
EnergyExportLow = 0
EnergyExportHigh =0
PowerImport = 0
PowerExport = 0
end

It must be use only the first time the script is call.

Thank you helped.
I ran once, then removed.

Now is:

"EventSystem: Script event triggered"


But do not change the meter reading, is still 0.0

There was my mistake with one of ID.

Its look like it took to T2 all of my already taken 22kWh. I will make some test now

Thank you!

OK Its working perfect!


What is the easiest way to put some daily/monthly data of usage or costs to another dummy or tex device? To show it in some external system like ImperiHome?

[supermat]

You can show that directly in domoticz. Inside the device.

idk if that possible in LUA, i made it in bash, take your counter IDX
Add dummy text sensor, take IDX

Code: Select all

#!/bin/bash
data=`curl --silent -is "http://ip:port/json.htm?type=devices&rid=IDX" |grep "CounterToday" |sed 's/"//g' |awk '{print $3}'`
string="http://ip:port/json.htm?type=command&param=udevice&IDX=120&nvalue=0&svalue="$data"kWh"
curl --silent $string

make that script executable with

Code: Select all

chmod +x filename.sh

and then add to cron like (every 1 min, for 5mins interval change first '*' with '*/5'

Code: Select all

* * * * * sh /home/pi/domoticz/scripts/daily.sh

in imperihome add it, change icon and its ok.

ive made the same script which do the same every day at 23:55 and show me usage from last day (left usage is prev day, right 'this' day)

[journeyman]

Thats great!
Thank you!

But how can i split it in to T1 and T2? To make calculation and show "Today costs"

[Abbadon]

no idea, probably need to call database

How can I extract in LUA the daily usage of a energie sensor?

I want to extract the daily solar power generation and send it through a notification with maybe some other information.

A simple extraction like this code will not work because it gives me only the total energy and current power.

Code: Select all

sEnergyPower, sEnergyTotal = otherdevices_svalues['Energie']:match("([^;]+);([^;]+)")

I can't extract the part from the French LUA because I don't understand it.

After yesterday update to Beta 3.8197 This counter with T1 T2 is not working anymore


Im getting this in log

Code: Select all

2017-08-03 09:38:00.277 Error: EventSystem: in Elektrownia: [string "function log(p_message)..."]:21: bad argument #1 to 'pairs' (table expected, got nil)

What can I do to solve that? Its stop working after update

Code: Select all

function log(p_message)
-- print("[HPHC] " .. p_message)
end
function getdevname4idx(deviceIDX)
 for i, v in pairs(otherdevices_idx) do
   if v == deviceIDX then
     return i
   end
 end
 return 0
end

commandArray = {}
DEBUG = false

local nomCompteurPrincipal = getdevname4idx(129) --OWL
local idxCompteurIntelligent = 133
local nomCompteurIntelligent = getdevname4idx(idxCompteurIntelligent)--HPHC
local nomHeureCreuse = getdevname4idx(134) -- Switch Heures Creuses

for deviceName,deviceValue in pairs(devicechanged) do
 if (deviceName==nomCompteurPrincipal) then
   -- On récupère la valeur du compteur unique => consEnergy
   ConsPower, consEnergy = string.match(otherdevices_svalues[nomCompteurPrincipal], "(%d+%.*%d*);(%d+%.*%d*)")
   log(ConsPower.."-"..consEnergy)
   --on somme les compteurs HP et HC => EnergyImport
   --http://www.domoticz.com/wiki/Upload_energy_data_to_PVoutput
   EnergyImportLow, EnergyImportHigh, EnergyExportLow, EnergyExportHigh, PowerImport, PowerExport = otherdevices_svalues[nomCompteurIntelligent]:match("([^;]+);([^;]+);([^;]+);([^;]+);([^;]+);([^;]+)")
  

  
   EnergyImport = EnergyImportLow + EnergyImportHigh
   EnergyExport = EnergyExportLow + EnergyExportHigh

   log(" ----- PowerImport = " .. PowerImport .. " W");
   log(" ----- EnergyImportLow = " .. EnergyImportLow .. " Wh");
   log(" ----- EnergyImportHigh = " .. EnergyImportHigh .. " Wh");
   log(" ----- EnergyImport = " .. EnergyImport .. " Wh");
   log(" ----- PowerExport = " .. PowerExport .. " W");
   log(" ----- EnergyExportLow = " .. EnergyExportLow .. " Wh");
   log(" ----- EnergyExportHigh = " .. EnergyExportHigh .. " Wh");
   log(" ----- EnergyExport = " .. EnergyExport .. " Wh");
 
   --On calcule le delta avec le compteur actuel
   delta = consEnergy - EnergyImport
 
   --On ajoute le delta sur le bon tarif
   if (otherdevices[nomHeureCreuse] == 'On') then
     EnergyImportLow = EnergyImportLow + delta
   else
     EnergyImportHigh = EnergyImportHigh + delta
   end
 
   --On modifie le compteur intelligent
   commandArray['UpdateDevice'] = idxCompteurIntelligent.."|0|"..EnergyImportLow..";"..EnergyImportHigh..";0;0;"..ConsPower..";0"

 end
end

return commandArray

Hi Brutus,

Just came along your update and need the answer as well. Did you get an update or/and do you know to get the daily usage with LUA?
Hope you can help me.

regards,

Jeroen

@Brutus, @Jeroenkl

This is not in Lua but in dzVents 2.4. You can try the following

Code: Select all

local Energy = domoticz.devices(Energie).rawData
domoticz.devices(Power).updateCounter(Energy[1])
domoticz.devices(TotalEnergy).updateCounter(Energy[2])

Of course this is somewhere in the middle of a dzVents script.
This works for me to parse all 6 values form the Electricity devicce of the P1 Smart Meter and update to different devices.

Correct me if I am wrong
