My LUA Script

commandArray = {}

-- Water usage
-- Retrieve value from water meter device:
sWaterUsage = otherdevices_svalues['Watermeter']

-- To have a better readable format, divide number by 1000:
sWaterUsagePrint = tonumber(sWaterUsage / 1000);

-- calculation is done with the unmodified water value
sWaterUsage = tonumber(sWaterUsage);

-- For Debuging
-- print("Water usage until now is " .. sWaterUsagePrint .. "m3 ");
-- print('GPIO Watermeter = '..otherdevices['GPIO Watermeter']);

if (devicechanged['GPIO Watermeter'] == 'Off')
then
sWaterUsageTot = (sWaterUsage + 1)

print("Water usage is now " .. sWaterUsageTot / 1000 .. "m3 ");
commandArray['UpdateDevice'] = '34|0|'..sWaterUsageTot..''
end

return commandArray

The red colored parts need to me reconfigured for your case.
To set the initial meter values http://<<YOUR DOMOTICZ IP>>/json.htm?type=command&param=udevice&idx=34&svalue=999999
Where "999999" = 999.999m3

Make sure to set LUA to DEVICE instead off ALL

os.execute('wget http://<<YOUR SLAVE DOMOTICZ IP>>/json.htm?type=command&param=udevice&idx=<<<YOUR SLAVE IDX>>>&svalue='..sWaterUsageTot..' -O /dev/null')
You can add it after the part with: commandArray['UpdateDevice'] = '34|0|'..sWaterUsageTot..'

Oh I see! Have to put my master pi's IP address, create a virtual counter sensor and put that virtual sensor's IDX to the IDX field.

In my case, I can’t get the info to the master Pi through the “master-slave” functionality but am I correct that with using the solution above, this is possible? Thnx!

Ok, i am really going to sound like a Noob here but I am lost.
what exactly do I need to copy and past into the Lua script?

thnx in advanced!!

thnx in advanced

Yes, that should be all.

if (devicechanged['Watermeter GPIO'] == 'Off')
then
	sWaterUsageTot = (sWaterUsage + 1)
	
	print("Water usage is set to " .. sWaterUsageTot / 1000 .. "m3 ");
	commandArray['UpdateDevice'] = '6|0|'..sWaterUsageTot..''
	os.execute('wget http://192.168.0.19:8080/json.htm?type=command&param=udevice&idx=3571&svalue='..sWaterUsageTot..' -O /dev/null')
else
    -- Keep a live device
    if (timedifference(otherdevices_lastupdate["Watermeter"]) > 300)
    then
        print("Water usage is still " .. sWaterUsage / 1000 .. "m3 ");
        commandArray['UpdateDevice'] = '6|0|'..sWaterUsage..''  
    end
end

return commandArray

You should also add "os.execute('wget http://192.168.0.19:8080/json.htm?......" to the keep alive part otherwise it shows offline after a time of no water usage. Instead of "os.execute" you can also try "commandArray["OpenURL"] = "http://....". This shouldn't make a difference but you can try.
