So if tomorrow it shows for example "heat_energy":"210.710" It means you have used 210.710-210.310=0.400 GJ today. Then we can use this value for a counter.

what I have now

IDX 251 is called 'heat_energy' (and gives 210,31GJ)
IDX 263 is my new dummy, zie screenshot


My code (in events, lua, type 'all'):

Code: Select all

local idx = 263
local heat_energy = domoticz_applyJsonPath(request['content'], '.heat_energy')
heat_energy = heat_energy * 1000
domoticz_updateDevice(idx, '251' , heat_energy)

I get an error:
' 2024-01-31 16:48:46.011 Error: EventSystem: in Dagtellerwarmte: [string "local idx = 263 ..."]:2: attempt to index a nil value (global 'request')'

domoticz_updateDevice(idx, '251' , heat_energy)

domoticz_updateDevice(idx, '' , heat_energy)

You should modify the Lua parser script kamstrup.lua in /domoticz/scripts/lua_parsers that you created according this instruction: https://haprofs.com/kamstrup-multical-s ... -domoticz/

Then you could make a Dummy Counter named Heating (or what you wish) see also https://www.domoticz.com/wiki/Dummy_for ... es#Counter
After creation, press on Edit and make it a Custom Counter (type = Counter)
Value Quantity: Heating Energy
Value Units: GJ
Counter divider: 1000 (this is important).

Add in your Lua parser script kamstrup.lua in /domoticz/scripts/lua_parsers the following. It could be that the multiply 1000 line gives an error as the value is a string and perhaps not recognized as a fractal. Please report back if it gives an error.

Code: Select all

local idx = [IDX of new Counter]
local heat_energy = domoticz_applyJsonPath(request['content'], '.heat_energy')
heat_energy = heat_energy * 1000
domoticz_updateDevice(idx, '' , heat_energy)

First value could be high as it could report complete history. you can delete this high value the next day (shift+ mouse click on value in the Graph) and then you have normal values.

When everything works well you can delete the custom sensor and the lua code that fills this custom sensor.
