Hello @waltervl Yes I know. But at the time I started this project I did not have the cost of electricity and gas visible in the Energy Dashboard and I did not understand why. I have now found in the forum how to take care of that. https://forum.domoticz.com/viewtopic.php?p=317557#p317557 However ...

Problem solved

See viewtopic.php?t=43344

For several years I have been using a script to calculate my energy costs. I once downloaded that from https://ehoco.nl/stroom-gas-en-waterkosten-zichtbaar-maken-domoticz/ but it was also in other places. Because I have another energy supplier who uses different rates and calculations I wanted to ...

@HvdW

This works excellent.
With this as a base, I can move on, and see what else I need, and customise it to my needs.
Great work.

Henny

@HvdW, Hello, I see you are an expert in this matter. I will implement and test it tomorrow. I spent quite some time experimenting again this afternoon, but to no result. Thanks for now and I'll let you know if it works and gives the result I'm hoping for. That sensor I'll call ‘EnergieRekening’ I th ...

@HvdW
Your AI generated script doesn't work neither.
Or the script is not right, or I'm doing something wrong.

Regards, Henny

Oké, thanks. I don't quite understand the inpact of your last sentence. I found the script here: https://ehoco.nl/stroom-gas-en-waterkosten-zichtbaar-maken-domoticz/ and here is something similar. https://krijnermerins.nl/domoticz/dagelijkse-energiekosten-weergeven-in-domoticz/ From the responses, I ...

Hello HELP :? :roll: What is wrong with this script?????? return { on = { timer = { 'every 2 minutes' }}, execute = function(domoticz, device, timer) local vandaagKwh = domoticz.devices('Power').counterToday local vandaagM3Gas = domoticz.devices('Gas').counterToday local StroomKosten = domoticz ...

Oké, Thanks (Bedankt! HvdW)

I'll work on it and see if I can get it working.

Hello, I hope someone can and will help me. I have a script I use to calculate my energy costs. That works. But..... Energy costs change annually, so to compare costs per year, I actually need to add a date line to that. I see in that script: if (domoticz.time == ‘Between 23:00 and 07:00’), but does ...

I am storing the costs components of my contract in user variables and then use a dzvent script to calculate the actual costs. The results are stored in some custom devices. Could that work for you? Note it does not take into account the daily low and high rate periods. Only uses high rate in the ...

STRANGE !!!!!! In an attempt to get column graphs of the cost of gas consumption I run into strange things. If I show the costs with a custom sensor, I get € 0.78. but when I turn it into a Counter I see € 0.78 in one place but € 0.22 in the top right (or often other values that do not match. When I ...

Oké. Now I have still one challenge...
How do I get 2 decimal place every where...
I did some testing and found that I can multiply with 100 in the script and then devide by 100 in the device..
But is there a neater way, better way to do that.

By modifing the script I came a littlebit further and now got this:
But kWh should be EUR and I have to get two decimals instead of 3 but I think I can solve that by editing the formular in the script...

Is it possible to define a new device-type based on an existing device type? Copy a device-type and modify it????

Hello, I hope to get an answer / solution to my challenge here. I read my energy consumption with a P1 module. That works. I found a script to calculate consumption to Energy costs and it works too. However, I see a line graph in the “log” of Gas costs and I would like a bar graph the same I see wit ...
